Re: validating xml with schema and libxml - expression could not be compiled

validating xml with schema and libxml - expression could not be compiled | Re: validating xml with schema and libxml - expression could not be compiled
& XSLT Hi,

Check if xmllint validates your document. If not and you are sure your schema 
is correct, then the problem probably lies in libxml2 and you should report 
there (see http://xmlsoft.org/bugs.html).
