Do you really mean string as return type of fn:nid?

Update of /cvsroot/monetdb/pathfinder/compiler/semantics In directory sc8-pr-cvs7.sourceforge.net:/tmp/cvs-serv8300/compiler/semantics

Modified Files: xquery_fo.c Log Message: fast NID node retriveal by NID

• moved support for id/idref node retrieval into pathfinder.mx having this as an API function will allow us to provide this functionality using indices later (i.e. be able to lock and isolte a hash index). it also helps a port of this functionality to algebra.

  for the moment, there are no shared hash tables, and ID/IDREF queries on updatable XML documents will be slowish (sequential scans needed) the new NID access is a good alternative to look up nodes.

• implemented in ID node retrieval support for string sthat are numbers, these are interpreted as NIDs, not ID attributes.

• implemented a new fn:nid(element()*) as xs:string* builtin function that returns the NIDs of element nodes.

• fixed some constant support things (mposjoin)
