“undefined namespace prefix” with XSLT prefix and two predicates
I've caught yet another libxml2/libxslt bug: Bug 407731.
Consider the stylesheet (test.xsl):
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="*[xsl:template][1]">
<x/>
</xsl:template>
</xsl:stylesheet>
Let run it:
$ ~/p/third_party/libxslt/opt/bin/xsltproc test.xsl test.xsl XPath error : Undefined namespace prefix <?xml version="1.0"?> <x/>
Note the error "Undefined namespace prefix" is appeared, but there is no error. And, for example, Saxon doesn't complaint.
The funny thing is that if I change "*[xsl:template][1]" to "*[xsl:template]", the error is disappeared.
