XmlResults XmlStackFrame::query(const std::string &queryString) const

Prepares and executes the query given in the dynamic context of the stack frame. This can be used to examine the value of the context item (".") or variables ("$var") for a given stack frame as well as other parts of the dynamic context. Users may find that the context item and variables present in their original query do not exist during query execution due to optimization performed by BDB XML.
