Enlightenment can often by achieved through the application of the
well-known expression RTFM :-) :
   http://xmlsoft.org/html/libxml-hash.html#xmlHashCreate
Similar information can be gleaned from include/libxml/hash.h, not to
mention the comments in the source code (hash.c).

Looking through the available hash functions, I'd say that
xmlHashScanFull may well fulfill your wishes, if you write a very simple
callback function to print the data presented to the callback.
