  I have no idea what you're trying to do, nor what you problem is.
xmlHashScan is used to traverse a hash table. The xmlHashScanner
argment is called for each element in the table with the content
in the hash, the data you passed and the name of the data in the hash
as the third argument. There is nothing assumed about data.
