Functions
: the full QName
xsltSplitQName: @dict: a dictionary @prefix: the return value Split QNames into prefix and local names, both allocated from a dictionary. Returns: the localname or NULL in case of error.
const xmlChar *	xsltSplitQName (xmlDictPtr dict, const xmlChar *name, const xmlChar **prefix)

: the attribute name
xsltGetNsProp: @node: the node @nameSpace: the URI of the namespace Similar to xmlGetNsProp() but with a slightly different semantic Search and get the value of an attribute associated to a node This attribute has to be anchored in the namespace specified, or has no namespace and the element is in that namespace. This does the entity substitution. This function looks in DTD attribute declaration for FIXED or default declaration values unless DTD use has been turned off. Returns the attribute value or NULL if not found. It's up to the caller to free the memory.

reorder the current node list accordingly to the set of sorting requirement provided by the arry of nodes.
