If I can interject here, exactly how strings are compared in XSL 1.0 has been an area of some confusion for me. Doug Tidwell's O'Reilly book states: "If both objects are strings: Then they are equal if their Unicode characters are identical. For less-than and greater-than comparisons, the character codes are compared." I've been told by people at Microsoft that this interpretation of the spec is wrong but that early versions of MSXML (not sure which ones) used this same mistaken interpretation, but MSXML4 doesn't. At the time, I tried to figure it out what the spec was saying for myself, but didn't get very far -- I was a bit out of my element at that point. It sounds like this agrees with what Michael is saying. -- Brook > From: "Michael Kay" <mhk@xxxxxxxxx> > Reply-To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Date: Mon, 6 Oct 2003 16:46:31 +0100 > To: <xsl-list@xxxxxxxxxxxxxxxxxxxxxx> > Subject: RE: xsl Greater than and Less than. > > If I decode your message correctly, you are using whatever processor > Microsoft Windows gives you.
