[xml] XML tree structure validity

["Theodore H. Smith" <delete elfdata com>]

Hi list,

Is there an inbuilt function to check the tree structure for validity  
according to libxml's way of doing things?

Basically, just to make sure I didn't screw up the nodes by accident.

I'm still new to libxml2, and I'm writing code like this:

inline void My_XMLMoveChildren( xmlNode* From, xmlNode* Into ) {
        xmlNode* Next = 0;
        
        for ( xmlNode* Child = From->children;  Child != 0 ;  Child = Next ) {
                Next = Child->next;
                xmlUnlinkNode(Child);
                xmlAddChild( Into, Child );
        }
}

For all I know, it could work, or it might look like it works but  
actually be creating an inconsistant tree node structure, something  
that might not be immediately apparant but which could cause errors  
later in my code.

Now, if there was some sort of validity or sanity checking function  
in libxml2, I could pin down any bugs I create far more quickly.

Is there such a function?
