This is _not_ valid XML! There's no way you will be able to convince
the XML parser (which is part of LibXML and not LibXSLT) to parse this.
While you could solve the nested quote problem by using single quotes
for the outer quoting (or vice versa, assuming Apache can handle single
quotes) you still end up with the (invalid) '<' character in the 
hre attribute.

Well, you _could_ write your own parser that tollerates this kind
of invalid XML but if you intend to output the same kind o stuff
you'd also have to write a serializer. Probably not worth the effort.
