Hi All, Thanks Derek, Mike, and Jeri for the replies. So....given the aforementioned xml dom ( see below ) and assuming ROOT is the current context node, then A[B[@NM = "case1"]/text() = A[B[@NM = "case3"]/text()]] ^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^ should find the A nodes with IDs 'match1' and 'match2' ? (the IDs are just for conversational clarity). If so, please be so kind as to clarify, because I cannot get this to work. The Xpath expression you show doesn't find any nodes, it is a boolean expression, it just returns true or false. A[B[@NM = "case1"]/text() returns a node set of all the text nodes of the selected A node. there are three nodes in that set with values { " " , " " , " --- " } The right hand side similarly is a node set of three nodes (which have the same values, as far as I can see) = applied to node sets is true if there exists a node in each set with equal values. This is true in this case. <ROOT> <A ID="match1"> <B NM="case1">abc</B> <B NM="case2">xyz</B> --- </A> <A ID="match2"> <B NM="case3">abc</B> <B NM="case4">def</B> ---- </A> <A> <B NM="case5">lmn</B> <B NM="case6">qrs</B> ---- </A> </ROOT> _____________________________________________________________________ This message has been checked for all known viruses by Star Internet delivered through the MessageLabs Virus Control Centre.
