[xml] libXML2

["Deepak Venkataraman" <deepakv hotmail com>]

I am using libXML2 (2.6.x) and have a few questions:

- LIBXML_TEST_VERSION: can this exit the application or does it simply print 
a warning?

- xmlCleanupParser(); may this be called only once from within an 
application or can it be called within threads as well? No, let me rephrase: 
is this thread-safe?

- I try to assign a string like:
 mdolinktarget = (char *)xmlNodeListGetString(doc, 
tmp_node->xmlChildrenNode, 1);
 and pass it as a reference to main but when I print it the string is 
empty, I have to instead do:
 strcpy(mdolinktarget,(char *)xmlNodeListGetString(doc, 
tmp_node->xmlChildrenNode, 1));
to make it work. Do you know why?
The problem is the first way we have now way knowing how long these buffers 
need to be;

thanks
