Thanks.

I dug around in the libxml code and the Web to verify that validation
is indeed only possible in libxml when one uses DOM (i.e. xmlTreeParse()).
Do you really need to validate the input? Given the size of the source,
it must be created automatically and so I tend to think it is either
correct or not, but that errors will be found with the creation
mechanism.


BTW, there is a new version of the XML package on the Omegahat web site.
It has several new features, including a function to find nodes via
XPath expressions, SAX2 support, recursive support for
xmlElementsByTagName().
