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}
