I'm not sure.
If I just declare "xmlns=http://foo.com", which has always been my
understanding was for default namespaces in XSL [1] ...
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://www.w3.org/1999/xhtml"
version = "1.0" >
....the following error is printed to STDERR all over the place...
Prefix must not be undef in get_uri(). The emtpy prefix must be '' at
/usr/local/lib/perl5/site_perl/5.005/XML/NamespaceSupport.pm line 194.
If I declare...
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:html="http://www.w3.org/1999/xhtml"
version = "1.0"
....the new file contains the truly weird...
<?xml version='1.0' encoding='ISO-8859-1'?>
<html xmlns:xhtml='http://www.w3.org/1999/html' xhtml:xmlns='http://www.w3.org/1999/html'>
I don't have time to look right now, but I will try digging through
XML::NamespaceSupport later today to see if the problem lies there.
If I use same code from the SYNOPSIS for XML::LibXSLT, specify the xmlns
as either "xmlns=" or "xmlns:html=" and use the parse_file method, the
XPath queries continue to fail. If I switch to the "parse_html_file"
method, everything is honky-dorry.
