XSLTC creates namespace nodes when it could re-use existing ones in scope.
--------------------------------------------------------------------------
Key: XALANJ-2411
URL: https://issues.apache.org/jira/browse/XALANJ-2411
Project: XalanJ2
Issue Type: Bug
Affects Versions: The Latest Development Code, 2.7.1
Reporter: Brian Minchau
Assignee: Brian Minchau
XSLTC creates extra namespace nodes, mapping ns0, ns1 ... to URIs when an
existing namespace mapping is
in scope and its prefix could be used (or the default namespace could be used).
Here is a stylesheet showing the problem:
<?xml version="1.0" encoding="UTF-8"?>
<!-- bug.xsl -->
<xsl:stylesheet version="1.0"
xmlns="http://uri1";
xmlns:prfx2='http://uri2'
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" indent="yes" />
<xsl:template match="/">
<out2>
<xsl:call-template name="makeElement1">
<xsl:with-param name="tagName" select="'elemName1'" />
</xsl:call-template>
<xsl:call-template name="makeElement2">
<xsl:with-param name="tagName" select="'elemName2'" />
</xsl:call-template>
<xsl:call-template name="makeElement3">
<xsl:with-param name="tagName" select="'elemName3'" />
</xsl:call-template>
</out2>
</xsl:template>
<xsl:template name="makeElement1">
<xsl:param name="tagName"/>
<xsl:element name="{$tagName}" namespace='http://uri1'/>
</xsl:template>
<xsl:template name="makeElement2">
<xsl:param name="tagName"/>
<xsl:element name="{$tagName}" namespace='http://uri2'/>
</xsl:template>
<xsl:template name="makeElement3">
<xsl:param name="tagName"/>
<xsl:element name="{$tagName}" namespace='http://uri3'/>
</xsl:template>
</xsl:stylesheet>
When run with any XML input, or this one, bug.xml:
<?xml version="1.0" encoding="UTF-8"?><doc/>
Using say the process command:
java org.apache.xalan.xslt.Process -XSLTC -IN bug.xml -XSL bug.xsl
The output is this:
<?xml version="1.0" encoding="UTF-8"?><out2 xmlns:prfx2="http://uri2";
xmlns="http://uri1";>
<ns0:elemName1 xmlns:ns0="http://uri1"/>
<ns1:elemName2 xmlns:ns1="http://uri2"/>
<ns2:elemName3 xmlns:ns2="http://uri3"/>
</out2>
The output should be:
<?xml version="1.0" encoding="UTF-8"?><out2 xmlns:prfx2="http://uri2";
xmlns="http://uri1";>
<elemName1/>
<elemName2 xmlns="http://uri2"/>
<elemName3 xmlns="http://uri3"/>
</out2>
