Welcome to the wonderful world of namespaces.
Try adding to your xsl:stylesheet
xmlns:xhtml="http://www.w3.org/1999/xhtml";
And in your XPaths use the namespace like so:
count(//xhtml:img)
Does that fix it? If so, this is not a Sab bug.
The selector in your XPath (img) is in no namespace (sometimes known as the
null namespace). The target in your document is in the XHTML namespace.
When you remove the default xmnls declaration from your input document,
things work, because then your input is in the null namespace also.
Tidy is doing the right thing; see the XHTML spec. It is also *correct* for
count(//img) *not* to match <img xmlns="http://www.w3.org/1999/xhtml";>.
(See http://www.w3.org/TR/xpath#node-tests).
I just noticed that libxslt gets this wrong, though. I don't have Sab on
this particular machine, so I can't test to see if it behaves properly (like
Saxon) or improperly like libxslt).
This is basically not a Sab question at all; on namespaces and all other XSL
issues see the XSL faq at http://www.dpawson.co.uk.
