Either in the expression itself or in the execution tree is fine with me, but it must be in a sequential order. Currently, i'm trying to implement a small subset of XPath specs to do the selection on the encoded XML file (in binary format). If i know each location step incrementally then i can search only the necessary parts of the encoded XML file and skip the rest. So hopefully the search will be faster. Son
