The 162 global variables, 9 keys (ʞ = key), 215 functions, and 117 templates (Ŧ = named template; ŧ = template mode) defined in the TAN function library, are the following:Dependencies refer exclusively to components of the TAN function library, both the core validation procedures and the extra functions. A variable, function, or template listed as not being relied upon may have dependencies in the files in the subdirectory applications.The contents of this chapter have been generated automatically. Although much effort has been spent to ensure accurate representation of the schemas and function library, you may find errors or inconsistencies. In such cases, the functions and schemas (particularly the RELAX-NG, compact syntax) are to be given priority.ŧ #all tan:aaa-to-int() tan:acronym() tan:add-attribute() ŧ add-collation-pos-offset ŧ

Output: <analysis> with an expansion of the sequence placed in children elements that have the name of the second parameter (with @attr); those children have @from or @to if part of a range. If a sequence has a numerical value no numerals other than Arabic should be used. That means @pos and @chars in their original state, but also if @n, then it needs to have been normalized to Arabic numerals before entering this function The exception is @ref, which cannot be accurately converted to Arabic numerals before being studied in the context of a class 1 source This function expands only those @refs that are situated within an <adjustments>, which needs to be calculated before being applied to a class 1 source. If this function is asked to expand ranges within a @ref sequence, it will do so under the strict assumption that all ranges consist of numerically calculable sibling @ns that share the same mother reference. Matt 1 4-7 is ok. These are not: Matt-Mark, Matt 1:3-Matt 2, Matt 1:3-4:7 If a request for help is detected, the flag will be removed and @help will be inserted in the appropriate child element. If ranges are requested to be expanded, it is expected to apply only to integers, and will not operate on values of 'max' or 'last' This function normalizes input numerals and strings.

TAN-core-functionstan:collate-pair-of-sequences($string-sequence-1 as xs:string*, $string-sequence-2 as xs:string*) as element()*Input: two sequences of strings Output: an element sequence that collates the two sequences as a single sequence, attempting to preserve the longest common subsequence. This function has been written for two different scenarios: 1. @n values in two sets of <div>s that must be collated; 2. pre-processing two long strings that need to be compared. Although the primary context are two sets of unique string-sequences, one could imagine situations where one or both input strings have repetition, in which case it is best to retain information about the sequence. Hence the output is a sequence of elements, with @p1, @p2, or both signifying the position of the original input. Hence the transformation is lossless, and the original input can be reconstructed if needed.

TAN-core-3-0-functionstan:longest-ascending-subsequence($integer-sequence as item()*) as element()*Input: a sequence of items. Each item is either an integer or a sequence of integers (via child elements) Output: a sequence of elements. Each one has in its text node an integer greater than the preceding element's text node. Each output element has a @pos with an integer identifying the position of the input item that has been chosen (to handle repetitions in the input) Although this function claims by its name to find the longest subsequence, in the interests of efficiency, it applies the so-called Patience method of finding the string, which may return only a very long string, not the longest possible string. Such an approach allows the number of operations to be directly proportionate to the number of input values (backtracking would be computationally intensive on long sequences). The routine does "remember" gaps. If adding a number to the sequence would require a jump, the sequence is created, but a copy of the pre-gapped sequence is memoized, in case it is later discovered that the pre-gapped sequence is better. The input is a sequence of elements, not integers, because this function has been written to support tan:collate-pairs-of-sequences(), which requires choice options. That is, you may have a situation where you are comparing two sequences, either of which may have values that repeat, e.g., (a, b, c, b, d) and (c, b, d). The first sequence is converted (1, 2, 3, 4, 5). In finding a corresponding sequence of integers for the second set, b must be allowed to be either 2 or 4, i.e., the array [3, [2, 4], 5]. Both items of input would ideally be expressed as arrays of integers, but this function serves an XSLT 2.0 library (where arrays are not recognized), and arrays are not as easy to construct in XSLT 3.0 as maps are.

Focus is placed on only those characters whose Unicode name has words matching $words-in-name-to-drop.. Other words in the first matching name are retained, and a search is made for any other Unicode character that has names specified by $words-in-replacement-char-name and does not have words specified by $words-not-in-replacement-char-name.. If the boolean is false, then the search will return Unicode codepoints that might have other words in their name; otherwise the match must correspond to all words in the target name. If the character does not have an entry in the $replace-guide, the original character is returned. The process will be applied to a char against only the first name found, not aliases. To use this function optimally, first bind the second parameter to a global variable, using rgx:build-char-replacement-guide(), then use the 2-parameter version of this function. Used by function rgx:replace-by-char-name().Does not rely upon global variables, keys, functions, or templates.

Option 1 (regex-ext-tan-functions)rgx:string-base($arg as xs:string?) as xs:string?one-param version of the fuller one, below Used by function rgx:string-base(), rgx:process-regex-escape-u().Relies upon rgx:string-base().Option 2 (regex-ext-tan-functions)rgx:string-base($arg as xs:string?, $version as xs:double) as xs:string?This function takes any string and replaces every character with its base Unicode character. This function is useful to prepare a text to be searched without respect to accents. E.g., ἄνθρωπός - > ανθρωπος Note, the ς is retained because it doesn't decompose. To match on σ one needs to use the flag 'i' (case insensitive) because ς case-folds to σ. This function is similar to rgx:string-to-components(), but strictly enforces a one-for-one replacement, so that it behaves much like fn:lower-case() and fn:upper-case(), where the string length is always preserved. To this end, this function is based on fn:translate(), and uses simple decomposition databases, which are much smaller and quicker to use than are full decomposition databases. The strict one-for-one replacement observes the following rules: If a character decomposes to a single character, that single character is returned. If a character decomposes to multiple characters that are identical, that single character is returned, e.g., ‴ to ′ If a character decomposes to multiple characters, a distinction is made between base and non-base characters: - Base characters: \p{Lu}\p{Ll}\p{Lt}\p{Lo}\p{N}\p{S} - Non-base characters: \p{Lm}\p{M}\p{P}\p{Z}\p{C} If after non-base characters are removed there is not exactly one unique decomposed character left, the original input is retained. The above rules are already reflected in the contents of the simple decomposition database, so do not need to be expressed in this function. For more, see ucd/ucd-decomp.xsl. Used by function rgx:string-base(), rgx:process-regex-escape-u().Relies upon rgx:get-ucd-decomp-simple-db().

Output: one string per character in the input; if a character lends itself to decomposition, its component parts are returned, otherwise the character itself is returned. This function is the inverse of rgx:string-to-composites(). If you wish to have more control over which components are returned (e.g., exclusion of combining marks), consider using either rgx:string-base() or the database directly: rgx:get-ucd-decomp-db().

TAN-class-1-functionstan:analyze-leaf-div-string-length($document-fragment as item()*) as item()*Input: any class 1 document fragment, or result of tan:diff() Output: Every leaf div or common/a/b stamped with @string-length and @string-pos, indicating how long the text node is, and where it is relative to all other leaf text nodes, after TAN text normalization rules have been applied. This function is useful for statistical processing, and for comparing a TAN-T(EI) file against a redivision. It has also been designed to stamp the <a> and <common> results of tan:diff(), to facilitate SQFs that replace a text with that of the other version. This function does the same thing as tan:analyze-string-length(), but approaches the problem with a recursive loop Used by template ŧ class-1-expansion-verbose-pass-1.Relies upon tan:analyze-leaf-div-text-length-loop().

TAN-class-1-functionstan:analyze-leaf-div-text-length-loop($items-to-process as item()*, $char-count-so-far as xs:integer, $return-final-count as xs:boolean) as item()*Loop function for the master one, above. Used by function tan:analyze-leaf-div-string-length(), tan:analyze-leaf-div-text-length-loop().Relies upon tan:analyze-leaf-div-text-length-loop(), tan:normalize-div-text(), tan:string-length().

Output: the same document, with @string-length and @string-pos added to every element Function to calculate string lengths of each leaf elements and their relative position, so that a raw text can be segmented proportionately and given the structure of a model exemplar. NB: any $special-end-div-chars that terminates a <div> not only will not be counted, but the assumed space that follows will also not be counted. On the other hand, the lack of a special character at the end means that the nominal space that follows a div will be included in both the length and the position. Thus input... <div type="m" n="1">abc&#xad;</div> <div type="m" n="2">def&#x200d;</div> <div type="m" n="3">ghi</div> <div type="m" n="4">xyz</div> ...presumes a raw joined text of "abcdefghi xyz ", and so becomes output: <div type="m" n="1" string-length="3" string-pos="1">abc&#xad;</div> <div type="m" n="2" string-length="3" string-pos="4">def&#x200d;</div> <div type="m" n="3" string-length="4" string-pos="7">ghi</div> <div type="m" n="4" string-length="4" string-pos="11">xyz</div> This function does the same thing as tan:analyze-leaf-div-string-length(), but approaches the problem in a two-template cycle, instead of a loop Used by function tan:analyze-string-length().Relies upon ŧ analyze-string-length-pass-1, ŧ analyze-string-length-pass-2.

Output: The div structure of (2), infused with the content of (1). The content is allocated proportionately, with preference given to punctuation, within a certain range, and then word breaks. This function is useful for converting class-1 documents from one reference system to another. Normally the conversion is flawed, because two versions of the same work rarely synchronize, but this function provides a good estimate, or a starting point for manual correction. The raw text will be tokenized based on the third parameter, so that, if you so wish, words, clauses, or sentences are not broken up.

Each item in the sequence is space normalized and then if its end matches one of the special div-end characters, ZWJ U+200D or SOFT HYPHEN U+AD, the character is removed; otherwise a space is added at the end. Zero-length strings are skipped. This function is designed specifically for TAN's commitment to nonmixed content. That is, every TAN element contains either elements or non-space text but not both, which also means that space-only text nodes are effectively ignored. It is assumed that every TAN element is followed by a notional space. The second parameter is important, because output will be used to normalize and repopulate leaf <div>s (where special div-end characters should be retained) or to concatenate leaf <div> text (where those characters should be deleted) Used by template ŧ tokenize-div, ŧ core-expansion-terse, ŧ text-join.Used by function tan:normalize-div-text(), tan:analyze-leaf-div-text-length-loop().Relies upon $special-end-div-chars-regex, tan:normalize-div-text().

TAN-class-1-functions.xsl <xsl:template match='/*' mode='merge-tan-docs' />A merged TAN-T file is a collation of multiple TAN-T(EI) files, with each head preserved intact, and the single body consisting of a hierarchy of divs grouped by a common reference scheme, dictated by @n.. This function has assumed the following principles, most important first: - merged output need not have everything needed to reconstruct the original sources, but the data must permit enough differentiation among sources to facilitate a variety of later uses, and therefore different configurations: - merged versions should retain their relative order - in a merge, <div>s should be sorted by numerical order, or by relative order, taking the group of divs as a whole - merges on the leaf div level should not lack any version, including versions that span or bridge other leaf divs - if a merge results in multiple copies, or parts, of a div, the div should be tagged with appropriate metadata The above list will be better understood in light of specific challenges in class 1 merges, discussed below. Some challenges in merging TAN-T files, discussed point by point: Challenge: A div with a particular ref/n might be split, with other divs in-between Resolution: all split divs will be grouped together, because the whole point of a merge is, well, to merge. Suppose you had to merge a leaf div from version A with a split leaf div from version B. If you did not fully merge B you would need to move A into one B split or the other, or put one copy of A in one split and another in the other. The situation would get even more complicated for a version C with non-leaf divs that would need to be merged. On the other hand, the grouping does not mean consolidation. The two, three, or more parts of a split div will be preserved as sibling elements within a merge. To assist in later processing, such split divs will be given @part and @part-count and appropriate integers (to be able to express something like "part 1 of 3"). In addition, each split div element will have the same value for @q, to facilitate referencing. Challenge: A particular version might have a div where numerical @ns do not follow their original sequence (remember, a TAN-T file should follow the sequence of the text within the scriptum, not the reference system) Resolution: A merge necessarily has to rearrange divs. As a general rule, the order of divs should be determined by adhering to the numerical value of @ns.. Challenge: Many @ns are not numbers, and a non-numerical div may appear in rather different places in different versions. Resolution: The position of a merged div with a non-numerical @n should be determined in accordance with principles outlined above regarding the order of divs. Suppose you have version one with div @ns of (epigraph), (1), (2); version two with (1), (2), (epigraph). The merge should result, for better or worse, with the divs ordered: (1), (epigraph), (2). Similarly, a version one with divs (title), (1), (2), ... (59), (60) and a version two with divs (title), (1), should result in the order of version one, and not something like (1), (2), ... (15), (title), (16), ... (59), (60). The position of non-numerical divs should be determined by nearby numerical div context, specifically the closest previous numerical @n value, then the distance from it (i.e., calculate the number of intervening divs with non-numerical @n values that intervene). Challenge: Some non-numerical @n's appear in different orders in different versions. Resolution: An example of the challenge would be the Old Testament / Tanakh. Modern editions have an order of books that diverges from what is in the Septuagint, and a merge of those two versions, according to the principles outlined above, would result in an idiosyncractic order followed by no version. If the user wishes such divs to follow a particular order, it is up to a later process to re-sort the output. Challenge: Some @ns might have multiple values, with complex overlap patterns Resolution: In a merge, when the algorithm encounters multiple values of @n, any numerical values are retained, excluding any non-numerical values, and the numerals are treated as requiring distribution. That is, if @n points to multiple numerical references, copies of the div are to distributed to the atomic numerical values of @n.. If no non-numerical values are found, the values are treated as aliases, and invite merging, greedily. Numerical example: four divs with @n values of (The_Cow, 1), (The_Cow, 2), (1), (2). The non-numerical values are ignored for their numerical counterparts, resulting in two merge groups, one for 1, another for 2. Non-numerical example: three divs with @n values of (head), (head, title), (title). Greedy overlap of the aliases results in a single group. Mixed example: three divs with @n values of (head), (head, title, 1), (title). Because the middle term has a numerical value, the non-numerical values are ignored, resulting in three merge groups: head, 1, and title. This group too would be merged: Numerical example with ranges: four divs with @n values of (1), (2), (3), (1-3). The last @n value, a complex/spanning range, requires distribution. Three merge groups are created. The three copies of the fourth div are each imprinted with @copy (value 1, 2, or 3) and @copy-count (value 3). Each copy retains intact its @q id, and its content. If an application using a merge requires the content to be reallocated proportionately, it will need to perform that operation upon the merged output. (There are many methods of proportional reallocation, and some of them require inspection of other versions that are in the merge, so there is little point in implementing in this merge algorithm a complex process that many users will not find useful or representative of their assumptions.) The position of merged divs follow the principles detailed earlier. Those with numerical references retain their position relative to their @n value. Those with only non-numerical references will attract a position computed by their position relative to the closest preceding div with a numerical value for @n.. <xsl:template match='tan:head' mode='merge-tan-docs' /><xsl:template match='tan:body | tan:div' mode='merge-tan-docs' /><xsl:template match='tan:ref' mode='merge-tan-docs merge-tan-doc-leaf-divs' /><xsl:template match='tan:_weight | tan:_rel-pos | tan:_n-pos | tan:_n-integer | tan:non-numbered' mode='merge-tan-docs merge-tan-doc-leaf-divs stamp-with-src-attr' />TAN-core-functions.xsl <xsl:template match='document-node()' mode='merge-tan-docs' />Used by function tan:merge-expanded-docs().Relies upon $separator-hierarchy, tan:distinct-items(), tan:group-divs-by-ref(), ŧ merge-tan-doc-leaf-divs, ŧ prep-div-refs-pass-1.

TAN-core-3-0-functions.xsl 3-parameter version of fuller one, below Input: a sequence of strings to be collated; a sequence of strings that label each string; a boolean indicating whether the sequence of input strings should be optimized; a boolean indicating whether the results of tan:diff() should be processed and weighed; a boolean indicating whether the collation should be cleaned up. Output: a <collation> with (1) one <witness> per string (and if the last parameter is true, then a sequence of children <commonality>s, signifying how close that string is with every other, and (2) a sequence of <c>s and <u>s, each with a <txt> and one or more <wit ref="" pos=""/>, indicating which string witness attests to the [c]ommon or [u]nique reading, and what position in that string the particular text fragment starts at. If there are not enough labels (2nd parameter) for the input strings, the numerical position of the input string will be used as the string label / witness id. If the third parameter is true, then tan:diff() will be performed against each pair of strings. Each diff output will be weighed by closeness of the two texts, and sorted accordingly. The results of this operation will be stored in collation/witness/commonality. This requires (n-1)! operations, so should be efficient for a few input strings, but will grow progressively longer according to the number and size of the input strings. Preoptimizing strings will likely produces greater congruence in the <u> fragments. If the last parameter is true, then cleanup will not be performed. This parameter was introduced because the cleanup process itself invokes tan:collate() and one does not want to get into an endless loop because of a mishmash of differences that can never be reconciled or brought closer together. This version of tan:collate was written in XSLT 3.0 to take advantage of xsl:iterate, and has an arity of 3 and 5 parameters to distinguish it from its XSLT 2.0 predecessors, which used a different approach to collation. Tests comparing the two versions of tan:collate() may be profitable. Changes in output from previous version of tan:collate(): - @w is now <wit> with @ref and @pos - the text node of <u> or <c> is now wrapped in <txt> - @length is ignored (the value is easily calculated) With these changes, any witness can be easily reconstructed with the XPath expression tan:collation/() TAN-core-string-functions.xsl one parameter version of full one below Input: any number of strings Output: an element with <c> and <u w="[WITNESS NUMBERS]">, showing where there are common strings and where there are departures. At the beginning are <witness>es identifying the numbers, and providing basic statistics about how much each pair of witnesses agree. This function was written to deal with multiple OCR results of the same page of text, to find agreement wherever possible. This function was rewritten in 2020 as an XSLT 3.0 function, with 5-arity.
