Re: [xml] libxml2 API crazy?

Thanks for that.

I guess my only comment is that doc->type and node->type are there for
a reason. But I agree it's a bit disingenuous to be traversing up a tree
via ->parent and discover that you've hit a node which is actually a xmlDoc.

In practice this means always having to have a special case test for
node->parent == node->doc or node->parent->type == XML_ELEMENT_NODE/XML_DOCUMENT_NODE and so on before you 
assume it really is a xmlNode.

I'm not even sure why the root node parent of a doc points to the xmlDoc
given that there is a node->doc value to use if you want it.
