Tbis is a bug report against the Xalan XSLT 3 development branch.
I am trying to store the result of `xsl:evaluate` in a variable and afterwards
use that variable. However, that results in an error "Variable $array accessed
before it is bound".
The code runs fine with Saxon HE 12.
Here is the sample XSLT:
{code:java}
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="3.0"
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:array="http://www.w3.org/2005/xpath-functions/array";
exclude-result-prefixes="xs array">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="data">
<xsl:variable name="array" as="item()">
<xsl:evaluate xpath="." context-item="."/>
</xsl:variable>
<xsl:value-of select="array:sort($array)"/>
</xsl:template>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/">
<xsl:copy>
<xsl:apply-templates/>
<xsl:comment>Run with <xsl:value-of
select="system-property('xsl:vendor')"/> at <xsl:value-of
select="current-dateTime()"/></xsl:comment>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
{code}
Here is the sample XML input:
{code:java}
<root>
<data>[3, 2, 1]</data>
</root>{code}
Full output:
{noformat}
file:///C:/Users/marti/IdeaProjects/xalan-java/../../OneDrive/Documents/xslt/blog-xslt-3-by-example/xalan-xslt3-tests/xsl-evaluate-array-literal1.xsl;
Zeilennummer14; Spaltennummer48; javax.xml.transform.TransformerException:
Variable $array accessed before it is bound!.{noformat}
Output expected:
{code:java}
<?xml version="1.0" encoding="UTF-8"?>
<root>
1 2 3
</root>{code}
