Error counting nodes when using a variable
------------------------------------------
Key: XALANJ-2293
URL: http://issues.apache.org/jira/browse/XALANJ-2293
Project: XalanJ2
Type: Bug
Components: Xalan
Versions: 2.7
Reporter: Ricotta
Priority: Critical
Consider the following XML file:
---------------------------------------------------
<xmldata>
<value/>
<value/>
</xmldata>
---------------------------------------------------
Consider the following XSL file:
---------------------------------------------------
<xsl:stylesheet version = '1.0'
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
<xsl:variable name="doc" select="xmldata"/>
<xsl:template match="xmldata">
<html>
<head/>
<body>
Number of elements: <xsl:value-of select="count($doc/value)"/>
<br/>
Number of elements: <xsl:value-of select="count($doc/value)"/>
<br/>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
---------------------------------------------------
As you can see, the output should be an html page showing the total number of
elements twice. However, this is the output:
---------------------------------------------------
Number of elements: 2
Number of elements: 4
---------------------------------------------------
Now consider the following XSL file:
---------------------------------------------------
<xsl:stylesheet version = '1.0'
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
<xsl:template match="xmldata">
<xsl:variable name="doc" select="."/>
<html>
<head/>
<body>
Number of elements: <xsl:value-of select="count($doc/value)"/>
<br/>
Number of elements: <xsl:value-of select="count($doc/value)"/>
<br/>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
---------------------------------------------------
Now the output is correct:
---------------------------------------------------
Number of elements: 2
Number of elements: 2
---------------------------------------------------
Comparing the two XSL files, the only diference is that the "doc" variable is
declared outside or inside the template.
Thank you!
