----------------------------------------
Key: XALANJ-2001
URL: http://nagoya.apache.org/jira/browse/XALANJ-2001
Project: XalanJ2
Type: Bug
Components: Xalan
Versions: 2.4
Environment: winXP, java 1.4.2_03, xalan 2.4.1
Reporter: Paul Treadaway
Priority: Minor
With the following xml file:
<?xml version = "1.0" encoding = "UTF-8"?>
<a>
<l>
25</l>
<b>
<l>
25</l>
<p>
123</p>
</b>
<b>
<l>
50</l>
<p>
567</p>
</b>
</a>
and the following stylesheet:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:fo="http://www.w3.org/1999/XSL/Format";>
<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="a">
<xsl:apply-templates select = "b"/>
</xsl:template>
<xsl:template match="b">
<xsl:apply-templates select = "p"/>
</xsl:template>
<xsl:template match = "p">
<xsl:if test = "normalize-space(../l) =
normalize-space(/a/l)">success</xsl:if>
</xsl:template>
<xsl:template match = "*"/>
</xsl:stylesheet>
the following error is produced:
(Location of error unknown)XSLT Error (java.lang.StackOverflowError): null
The following xml files do not cause the error to manifest:
<?xml version = "1.0" encoding = "UTF-8"?>
<a>
<l>25</l>
<b>
<l>
25</l>
<p>
123</p>
</b>
<b>
<l>
50</l>
<p>
567</p>
</b>
</a>
<?xml version = "1.0" encoding = "UTF-8"?>
<a>
<l>
25</l>
<b>
<l>25</l>
<p>
123</p>
</b>
<b>
<l>50</l>
<p>
567</p>
</b>
</a>
Suggesting that it only occurs when the content of at least one matched node on
both sides of the equality test begins with a newline per run.
