thanks for Xquery info, I do not start to implenment the xmlquery() itself ,
maybe call xqilla lib or sth else in the future.
I think xmltable is almost equal to xmlquery , except that it retuns
talbeset insead of xml.
I take xmlconcat as an example , add xmlquery whereever xmlconcat appers and
nothing else.
the first problem is , I have to make xmlquery accepted by the parser.
