To evaluate an XPath expression held as a string, you need an extension
function such as dyn:evaluate().
Saxon 8.2 has a new form of this function, saxon:evaluate-node(), designed
for use when the XPath expression is held in a source document: it's
different from saxon:evaluate() in that it takes the namespace context from
the node in which the expression appears.

Subject: [xsl] Xpath as variable, then processing it
Hi all,
I have a little question :
I have a small XML Data containing in one of its field an Xpath (as
text) which should be used in an XSL-T for querying data in
another XML
using this XPath. The following XSL handles it as a variable.
<Classes>
<Class>
<Architecture name="Application" abr="AA">
<xsl_File name="App_Apt_Apx_Applications"
file="App_Apt_Apx_Applications.xsl"
XPath="/Classes/Class/SADefinition[starts-with(@SAObjName,'app_') or
starts-with(@SAObjName,'apx_') or starts-with(@SAObjName,'apt_')]"/>
(...)
Then, the XSL file looks as follow :
<xsl:stylesheet version="1.1"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:variable name="mainXML_node"
select="document('../XML/PM-EA-AA_IA_PA_TA.xml')"/> (The main XML)
<xsl:output method="html" version="1.0" encoding="UTF-16"
indent="yes"/>
<xsl:template match="/">
<xsl:result-document
href="../TCL/Temp/TCL_Data_Config.tmp">
<xsl:value-of disable-output-escaping="yes"
select="'{'"/>
<xsl:for-each-group
select="/Classes/Class/Architecture" group-by="@name">
<xsl:sort select="@name"/>
<xsl:value-of
disable-output-escaping="yes" select="concat('{',@name,' ')"/>
<xsl:for-each-group select="xsl_File"
group-by="@name">
<xsl:sort select="@name"/>
<xsl:variable name="path"
select="@XPath"/>
<xsl:value-of
disable-output-escaping="yes" select="concat('{',@name,' ')"/>
<xsl:for-each
select="$mainXML_node"> (Here is the problem)
<xsl:for-each-group
select="$path" group-by="@SAObjName">
<xsl:sort
select="@SAObjName"/>
(...)
I hope the upon the text is correctly indented by your mail browser.
Unfortunately, it won't work. Have anyone got an idea on how
to solve my
problem?
Best regards
Lawrence
