[xml] Removing all of the xml:X attributes from a node

[Rush Manbert <rush manbert com>]

I am trying to write a function that removes all attributes from an 
element using the tree interface. It seems that xml:lang, xml:id, and 
xml:space are special cases, since they have their own get and set 
functions.

Do I need to do anything special to remove these attributes from the 
node? My current code for "remove all attributes" is this:

inline void
removeAllNodeAttributes (xmlNodePtr pNode)
{
    xmlAttrPtr pAttr;
    while (NULL != (pAttr = pNode->properties))
    {
        xmlRemoveProp (pAttr);
    }
}

Thanks,
Rush
