& XSLT Hi,

I have just started using XML::LibXML 1.63 and have run into a problem  
when parsing chunks of XML that contain HTML entities.
There is no problem when parsing an entire document where I can include  
definitions of various (X)HTML entities that XML don't contain, but once I  
use the parse_balanced_chunk function that makes a document fragment out  
of a balanced chunk of XML, then I can't tell it to use a set of  
definitions from a document it could belong to.

I solved this partly by hacking into the C parts of LibXML allowing for an  
additional optional parameter that could be a context document (as the  
libxml2 function that is used by parse_balanced_chunk allows this).  
However, I have little experience making C modules for perl, and I might  
be doing something wrong, as when I later use the resulting DOM fragment  
with $dom_frag-> parentNode()->replaceChild($dom_frag,$inc_ele) it  
segfaults while reconsiling things. I suspect a) the code is not tested in  
the case of a dom fragment having a context document, or b) the pointer to  
the document might be wrongfully altered or wrong inside the C code.

The diff for my changes is currently: http://utilitybase.com/paste/4826

Example code using this: http://utilitybase.com/paste/4827

However, I was told that it might not be possible to hack in this  
functionality at all so if it isn't possible, does anyone have any hints  
on how I could parse a string of XML containing (X)HTML entities so that I  
can insert it into an XML document containing the right definitions?

(My temporary solution is to convert the (X)HTML entities to number  
entities right before using parse_balanced_chunk, and I _could_ also use  
CDATA wrappers around the code, but I don't like those solutions really.)

Apologies upfront if I failed to meet any criteria required when posting  
here. Feel free to enlighten me on how to do so correctly if that is the  
case.
