[xml] extension functions returning values into variables...

[Nic <nferrier tapsellferrier co uk>]

Can anyone tell me why this doesn't work:

    import string
    import libxml2
    import libxslt

    def func(ctx, *str):
        return "a string"

    libxslt.registerExtModuleFunction("foo", "http://example.com/foo";, func)
    styledoc = libxml2.parseDoc("""
<xsl:stylesheet version='1.0'
  xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
  xmlns:foo='http://example.com/foo'
  xsl:exclude-result-prefixes='foo'>
  <xsl:template match='/'>
    <xsl:variable name="myvar" select="string(//param/name['uri']/following-sibling::value)"/>
    <xsl:variable name="udpated" select="foo:foo($myvar)"/>
    <test><xsl:value-of select="$updated"/></test>
  </xsl:template>
</xsl:stylesheet>
""")
    style = libxslt.parseStylesheetDoc(styledoc)
    doc = libxml2.parseDoc("<doc><param><name>uri</name><value>xyz</value></param></doc>")
    result = style.applyStylesheet(doc, {})
    print result
    style.freeStylesheet()
    doc.freeDoc()

It should call 'func' with "xyz" and return "a string" into the
<test/> element.

But it doesn't it barfs.

If you do this:

    <xsl:variable name="myvar" select="string(//param/name['uri']/following-sibling::value)"/>
    <test><xsl:value-of select="foo:foo($myvar)"/></test>

it works.

That's not right is it?
