How to make variable text as Xpath expression - xslt-2.0

Please suggest to get Xpath expression from the variable text. As xpath expression is stored in a variable as a text. From earlier suggestions were suggesting evaluate function, but unable to get.
XML:
<article>
<float>
<fig id="fig1">Figure 1</fig>
<fig id="fig2" type="color">Figure 2</fig>
<fig id="fig3" type="color">Figure 3</fig>
<fig id="fig4" type="color">Figure 4</fig>
</float>
XSLT 2.0:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:param name="varColorFig"><xsl:text>//float/fig[#type='color']</xsl:text></xsl:param><!-- Xpath stored in variable as a text-->
<!--xsl:variable name="names" as="element(name)*"><xsl:evaluate xpath="$varColorFig" context-item="."/></xsl:variable-->
<xsl:template match="article">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
<xsl:element name="ColorFigCount">
<xsl:if test="count(//float/fig[#type='color']) gt 0">
<a><xsl:value-of select="count(//float/fig[#type='color'])"/></a>
</xsl:if><!--real Xpath expression format-->
<xsl:if test="count($varColorFig) gt 0">
<b><xsl:value-of select="count($varColorFig)"/></b>
</xsl:if><!-- xpath stored in variable as text, then needs to get as Xpath here, but it is not processing as Xpath.-->
</xsl:element>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Required Result: <b>3</b> is the required, but now getting 1.
<article>
<float>
<fig id="fig1">Figure 1</fig>
<fig id="fig2" type="color">Figure 2</fig>
<fig id="fig3" type="color">Figure 3</fig>
<fig id="fig4" type="color">Figure 4</fig>
</float>
<ColorFigCount><a>3</a><b>3</b></ColorFigCount>
</article>

In XSLT 3 with xsl:evaluate support your code would look as follows (assumes expand-text="yes" is enabled):
<xsl:param name="varColorFig"><xsl:text>//float/fig[#type='color']</xsl:text></xsl:param><!-- Xpath stored in variable as a text-->
<xsl:variable name="names" as="element(fig)*"><xsl:evaluate xpath="$varColorFig" context-item="."/></xsl:variable>
<xsl:template match="article">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
<colorFigCount>{count($names)}</colorFigCount>
</xsl:copy>
</xsl:template>
The xsl:param could be shortened to <xsl:param name="varColorFig">//float/fig[#type='color']</xsl:param>, I don't see a need for xsl:text.

XSLT: Delete certain characters from string with nested elements

I have a sequence of transformations that result with a penultimate output containing a code line of the following structure:
<hi rendition="#rf-Lyricist">
[Lyricist: <anchor xml:id="w1s"/>Some Name]<anchor xml:id="w1e"/>
</hi>
Transforming the tei:hi element into is not a problem. The square brackets surrounding the text should be transformed into a nested tei:supplied, so the desired result is:
<note type="lyricist">
<supplied reason="provided-by-editor" cert="1" resp="#NN">
Lyricist: <anchor xml:id="w1s"/>Some Name<anchor xml:id="w1e"/>
</supplied>
</note>
I tried several ways of achieving this, inlcuding:
<xsl:template match="tei:body/tei:div[1]/tei:lg/tei:l/tei:hi[(#rendition='#rf-Lyricist')]">
<!-- This method deletes all tei:anchor within the lyricist line. -->
<xsl:analyze-string select="." regex="\[.*\]">
<xsl:matching-substring>
<xsl:element name="note" namespace="http://www.tei-c.org/ns/1.0">
<xsl:attribute name="type">
<xsl:value-of select="'lyricist'"/>
</xsl:attribute>
<xsl:element name="supplied" namespace="http://www.tei-c.org/ns/1.0">
<xsl:attribute name="reason">
<xsl:value-of select="'provided-by-editor'"/>
</xsl:attribute>
<xsl:attribute name="cert">
<xsl:value-of select="'1'"/>
</xsl:attribute>
<xsl:attribute name="resp">
<xsl:value-of select="'#ND'"/>
</xsl:attribute>
<xsl:value-of select="translate(., '[]', '')"/>
</xsl:element>
</xsl:element>
</xsl:matching-substring>
</xsl:analyze-string>
</xsl:template>
I always get a result, where not only the square brackets, but also the tei:anchor elements are deleted, such as:
<note type="lyricist">
<supplied reason="provided-by-editor" cert="1" resp="#ND">
Lyricist: Some Name
</supplied>
</note>
The same method for replacing square brackets works perfectly well within a text node that has no further elements inside.
To implement "The square brackets surrounding the text should be transformed into a nested [..]supplied" I would use e.g.
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:fn="http://www.w3.org/2005/xpath-functions"
exclude-result-prefixes="#all"
version="3.0">
<xsl:mode on-no-match="shallow-copy"/>
<xsl:template match="hi">
<note type="lyricist">
<xsl:variable name="content">
<xsl:apply-templates mode="brackets-to-elements"/>
</xsl:variable>
<xsl:for-each-group select="$content/node()" group-starting-with="osb">
<xsl:choose>
<xsl:when test="self::osb">
<xsl:for-each-group select="tail(current-group())" group-ending-with="csb">
<xsl:choose>
<xsl:when test="position() eq 1">
<supplied>
<xsl:apply-templates select="current-group()[not(position() = last())]"/>
</supplied>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-group()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-group()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</note>
</xsl:template>
<xsl:mode name="brackets-to-elements" on-no-match="shallow-copy"/>
<xsl:template match="hi//text()" mode="brackets-to-elements">
<xsl:apply-templates select="analyze-string(., '\[|\]')" mode="analyze"/>
</xsl:template>
<xsl:template match="fn:match[. = '[']" mode="analyze">
<osb/>
</xsl:template>
<xsl:template match="fn:match[. = ']']" mode="analyze">
<csb/>
</xsl:template>
</xsl:stylesheet>
which is the approach outlined in my comment, that is, to use one pass to find and convert square brackets in text nodes inside of hi elements to elements like e.g. osb and csb and a second pass on that intermediary tree to use standard/classic pairs of `for-each-group group-starting-with="osb"/group-ending-with="csb" to establish the wrapper element.
Output is e.g.
<note type="lyricist">
<supplied>Lyricist: <anchor xml:id="w1s"/>Some Name</supplied><anchor xml:id="w1e"/>

How to create dynamic columns (same number of columns in header & row) using XSLT 2.0

I have an XML data source:
<ws:Report_Data xmlns:ws="urn:com.ws.report/Expense_Data">
<ws:Report_Entry>
<ws:uID>
<ws:id>1</ws:id>
</ws:uID>
<ws:Journal_Entry_Group>
<ws:Ledger_Accounts ws:Descriptor="Q1: TEST1">
<ws:ID ws:type="Ledger_Account_ID" ws:parent_type="Account_Set_ID"
ws:parent_id="Standard">Q1</ws:ID>
</ws:Ledger_Accounts>
</ws:Journal_Entry_Group>
<ws:line>
<ws:Number>000123</ws:Number>
</ws:line>
<ws:line>
<ws:Number>000124</ws:Number>
</ws:line>
</ws:Report_Entry>
<ws:Report_Entry>
<ws:uID>
<ws:id>2</ws:id>
</ws:uID>
<ws:Journal_Entry_Group>
<ws:Ledger_Accounts ws:Descriptor="Q1: TEST1">
<ws:ID ws:type="Ledger_Account_ID" ws:parent_type="Account_Set_ID"
ws:parent_id="Standard">Q1</ws:ID>
</ws:Ledger_Accounts>
<ws:Ledger_Accounts ws:Descriptor="Q2: TEST2">
<ws:ID ws:type="Ledger_Account_ID" ws:parent_type="Account_Set_ID"
ws:parent_id="Standard">Q2</ws:ID>
</ws:Ledger_Accounts>
</ws:Journal_Entry_Group>
<ws:line>
<ws:Number>000596</ws:Number> </ws:line>
</ws:Report_Entry>
</ws:Report_Data>
Based on the number of ws:ledger_accounts returned, I want to create the columns of the ledger account id and the description. The column header is generated dynamically as well (adding number _1, _2 and so on in the Ledger_Account_ID and Ledger_Account_Descheader name).
Based on the sample data source above, the second report entry has the highest number of ws:Journal_Entry_Group/ws:Ledger_Accounts returned, and so my header column should have 2 and the data row should have exact number of columns as well. The delimiter is <|> while the data row is enclosed with "".
Example expected Output:
uID<|>Ledger_Account_ID_1<|>Ledger_Account_ID_2<|>Ledger_Account_Desc_1<|>Ledger_Account_Desc_2|Number
"1"<|>"Q1"<|>""<|>"Q1: TEST1"<|>""<|>"000123"
"1"<|>"Q1"<|>""<|>"Q1: TEST1"<|>""<|>"000124"
"2"<|>"Q1"<|>"Q2"<|>"Q1: TEST1"<|>"Q2: TEST2"<|>"000596"
The XSLT code:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet exclude-result-prefixes="xsl" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:ws="urn:com.ws.report/Expense_Data">
<xsl:output method="text"/>
<xsl:variable name="linefeed" select="'
'"/>
<xsl:variable name="delimiter"><![CDATA["<|>"]]></xsl:variable>
<xsl:variable name="delimiter1"><![CDATA[<|>]]></xsl:variable>
<xsl:template match="/ws:Report_Data">
<xsl:text>uID</xsl:text>
<xsl:value-of select="$delimiter1"/>
<xsl:value-of select="ws:Report_Entry[count(.//ws:Ledger_Accounts) = max(../ws:Report_Entry/count(.//ws:Ledger_Accounts))]//ws:Ledger_Accounts/concat('Ledger_Account_ID',$delimiter1)" separator=""/>
<xsl:value-of select="ws:Report_Entry[count(.//ws:Ledger_Accounts) = max(../ws:Report_Entry/count(.//ws:Ledger_Accounts))]//ws:Ledger_Accounts/concat('Ledger_Account_Desc',$delimiter1)" separator=""/>
<xsl:text>Number</xsl:text>
<xsl:value-of select="$linefeed"/>
<xsl:apply-templates select="/ws:Report_Data/ws:Report_Entry/ws:line"/>
</xsl:template>
<xsl:template match="/ws:Report_Data/ws:Report_Entry/ws:line ">
<xsl:text>"</xsl:text>
<xsl:value-of select="../ws:uID/ws:id"/>
<xsl:value-of select="$delimiter"/>
<!-- Ledger_Account_IDs -->
<xsl:if test="count(../ws:Journal_Entry_Group/ws:Ledger_Accounts) > 1">
<xsl:for-each select="../ws:Journal_Entry_Group/ws:Ledger_Accounts">
<xsl:value-of select="normalize-space(ws:ID[#ws:type='Ledger_Account_ID'])"/>
<xsl:if test="position()!=last()">
<xsl:value-of select="$delimiter"/>
</xsl:if>
</xsl:for-each>
</xsl:if>
<xsl:value-of select="$delimiter"/>
<!-- Ledger_Account_Desc -->
<xsl:if test="count(../ws:Journal_Entry_Group/ws:Ledger_Accounts) > 1">
<xsl:for-each select="../ws:Journal_Entry_Group/ws:Ledger_Accounts">
<xsl:value-of select="normalize-space(#ws:Descriptor)"/>
<xsl:if test="position()!=last()">
<xsl:value-of select="$delimiter"/>
</xsl:if>
</xsl:for-each>
</xsl:if>
<xsl:value-of select="$delimiter"/>
<xsl:value-of select="ws:Number"/>
<xsl:text>"</xsl:text>
<xsl:value-of select="$linefeed"/>
</xsl:template>
</xsl:stylesheet>
But the output is incorrect, the data row is not sync up with the number of columns in the header. For the first two lines it only creates 1 ledger account id column, should have at least another ""<|> before it goes to Ledger_Account_Desc column and the header can’t make it incremental.
Incorrect Output:
uID<|>Ledger_Account_ID<|>Ledger_Account_ID<|>Ledger_Account_Desc<|>Ledger_Account_Desc|Number
"1”<|>"Q1"<|>"Q1: TEST1"<|>"000123"
"1”<|>"Q1"<|>"Q1: TEST1"<|>"000124"
"2"<|>"Q1"<|>"Q2"<|>"Q1: TEST1"<|>"Q2: TEST2"<|>"000596"
I would use the separator attribute of value-of and then use a function to wrap each value in quotes; XSLT 3 would be

XSLT 2.0 xsl:result-document every n elements

I have a XML as follows:
<list>
<element>1</element>
<element>2</element>
<element>3</element>
<element>4</element>
<element>5</element>
<element>6</element>
<element>7</element>
<element>8</element>
<element>9</element>
<element>10</element>
<element>11</element>
<element>12</element>
<element>13</element>
<element>14</element>
<element>15</element>
<element>16</element>
<element>17</element>
<element>18</element>
<element>19</element>
<element>20</element>
Then I use this template to write the content to a file
<xsl:template match="list">
<xsl:result-document href="file:///c:/temp/bic.txt">
<xsl:for-each select="element">
<xsl:value-of select="."/>
</xsl:for-each>
</xsl:result-document>
</xsl:template>
But now I want to split the output so each five elements go to a different file. How can I do that?
One way is to use positional grouping:
<xsl:template match="list">
<xsl:for-each-group select="element" group-adjacent="(position() - 1) idiv 5">
<xsl:result-document href="bic-{position()}.txt" method="text">
<xsl:value-of select="current-group()" separator=""/>
</xsl:result-document>
</xsl:for-each-group>
</xsl:template>

XPaths are not working in XSLT global functions

I have implemented the following xslt global function, but it is not allowing to use XPath expressions.
For Example: //Track_Chainings/Track_Chaining[Track_ID=$TrackID]/Begin_Adjacent_Track_ID !='' is throwing exception.
<xsl:function name="conn:getConnetion" as="xs:string">
<xsl:param name="TYPE" as="xs:string"/>
<xsl:param name="TrackID" as="xs:string"/>
<xsl:param name="SwitchID" as="xs:string"/>
<xsl:choose>
<xsl:when test="($TYPE = 'TrackBegin')">
<xsl:if test="((//Track_Chainings/Track_Chaining[Track_ID=$TrackID]/Begin_Adjacent_Track_ID !='') and (//Track_Chainings/Track_Chaining[Track_ID=$TrackID]/Begin_Adjacent_Track_ID !='0'))">
<xsl:sequence select="concat(concat((TrackID * 10000) , '#'), (concat((//Track_Chainings/Track_Chaining[Track_ID=$TrackID]/Begin_Adjacent_Track_ID * 10000), 1)))"/>
</xsl:if>
</xsl:when>
<xsl:when test="($TYPE = 'TrackEnd')">
<xsl:if test="((//Track_Chainings/Track_Chaining[Track_ID=$TrackID]/End_Adjacent_Track_ID !='') and (//Track_Chainings/Track_Chaining[Track_ID=$TrackID]/End_Adjacent_Track_ID !='0'))">
<xsl:sequence select="concat(concat(concat((TrackID * 10000) , 1) , '#'), (//Track_Chainings/Track_Chaining[Track_ID=$TrackID]/End_Adjacent_Track_ID * 10000))"/>
</xsl:if>
</xsl:when>
<!-- <xsl:otherwise></xsl:otherwise> -->
</xsl:choose>
</xsl:function>
Could you please let us know if our implementation is having any issues.
Thank you in advance
There is no context node or context item in a function, thus, if you want to access nodes from a certain document, you will need to define an xsl:param for that document or node and pass it in in the function call e.g.
<xsl:function name="conn:getConnetion" as="xs:string">
<xsl:param name="TYPE" as="xs:string"/>
<xsl:param name="TrackID" as="xs:string"/>
<xsl:param name="SwitchID" as="xs:string"/>
<xsl:param name="track-doc" as="document-node()"/>
<xsl:choose>
<xsl:when test="($TYPE = 'TrackBegin')">
<xsl:if test="(($track-doc//Track_Chainings/Track_Chaining[Track_ID=$TrackID]/Begin_Adjacent_Track_ID !='') and ($track-doc//Track_Chainings/Track_Chaining[Track_ID=$TrackID]/Begin_Adjacen
....
and then call the function with the right document e.g. <xsl:value-of select="conn:getConnection('foo', 't1', 's2', /)"/>

Saxon XSLT2.0 Extracting Numbers from the String

I am trying to Extract Integer from a String using Xslt2.0
For Example consider the string "designa80000dd5424d" and i need the two integers inside the string i.e "8000" and "5424"
I tried using translate function as below
select="translate($term,translate($term, '0123456789', ''), '')"
But it combines both the integers and gives the output as "80005424"
i need something which separates them
I tried using translate function as below
select="translate($term,translate($term, '0123456789', ''), '')"
But it combines both the numbers and gives the output as "80005424" i
need something which separates them
I. Here is a complete XSLT 1.0 solution:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/*">
<xsl:variable name="vSpaces">
<xsl:call-template name="makeSpaces"/>
</xsl:variable>
<xsl:variable name="vtheNumbers"
select="normalize-space(translate(., translate(.,'0123456789',''), $vSpaces))"/>
<xsl:call-template name="tokenize">
<xsl:with-param name="pStr" select="$vtheNumbers"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="tokenize">
<xsl:param name="pStr"/>
<xsl:param name="pInd" select="1"/>
<xsl:if test="string-length($pStr)">
<xsl:value-of select=
"concat($pInd, ': ',substring-before(concat($pStr, ' '), ' '), '
')"/>
<xsl:call-template name="tokenize">
<xsl:with-param name="pStr" select="substring-after($pStr, ' ')"/>
<xsl:with-param name="pInd" select="$pInd +1"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
<xsl:template name="makeSpaces">
<xsl:param name="pLen" select="string-length(.)"/>
<xsl:choose>
<xsl:when test="$pLen = 1">
<xsl:value-of select="' '"/>
</xsl:when>
<xsl:when test="$pLen > 1">
<xsl:variable name="vHalfLen" select="floor($pLen div 2)"/>
<xsl:call-template name="makeSpaces">
<xsl:with-param name="pLen" select="$vHalfLen"/>
</xsl:call-template>
<xsl:call-template name="makeSpaces">
<xsl:with-param name="pLen" select="$pLen -$vHalfLen"/>
</xsl:call-template>
</xsl:when>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
When this transformation is applied on the following XML document:
<t>designa80000dd5424dan1733g122</t>
the wanted, correct result is produced:
1: 80000
2: 5424
3: 1733
4: 122
Do note:
The last argument of the outer translate() is a string having the same number of characters as that of the input string, and each of these characters is a space.
II. XPath 2.0 shorter and simpler
This XPath 2.0 expression when evaluated produces the wanted sequence of numbers:
tokenize(., '[^\d]+')[.]
Here is an XSLT - based verification:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/*">
<xsl:variable name="vNumbers"
select="tokenize(., '[^\d]+')[.]"/>
<xsl:for-each select="$vNumbers">
<xsl:value-of select="concat(position(), ': ', ., '
')"/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
When this transformation is applied on the same XML document:
<t>designa80000dd5424dan1733g122</t>
the same correct result is produced:
1: 80000
2: 5424
3: 1733
4: 122
You could try it using tokenize with any non-digit sequences as the separator, i.e. using XPath 3.0 tokenize('designa80000dd5424d', '[^0-9]+')[normalize-space()]!number() or in XSLT/XPath 2.0 as for $t in tokenize('designa80000dd5424d', '[^0-9]+')[normalize-space()] return number($t) or you could use xsl:analyze-string (XSLT 2.0) or the analyze-string function (XSLT/XPath 3.0, but available with Saxon 9.7 HE).
