Mukul, Thanks for your response. I've attached a sample schema and test file (the schema is edited down from a much larger document, so it's structure may not make much sense.) The problem is in the <assert> in line 74 of the schema. (The simpler <assert> in line 73 works properly.) I suspect that you may be right about there being a namespace problem, because the <assert> in line 74 fails even if I wrap not() around it. So both <xsd:assert test="if (matches(@target, '.*')) then true() else false()" xpathDefaultNamespace="##targetNamespace"/> And <xsd:assert test="if not((matches(@target, '.*'))) then true() else false()" xpathDefaultNamespace="##targetNamespace"/> both fail, which makes it look like the processor is not finding the matches() function. The 'xpathDefaultNamespace="##targetNamespace"' attribute is something I stumbled across when trying to get some other assertions to work, but I admit that I don't really understand what effects it may be having. Thank you for your help. - Jim -----Original Message----- From: Mukul Gandhi [mailto:[email protected]] Sent: Wednesday, April 17, 2013 10:55 AM To: [email protected] Subject: Re: regular expression matching in <assert> Hi Jim, Our XSD 1.1 <assert> implementation can use XPath 2.0 matches() and tokenize() functions fine. Our <assert> XPath 2.0 processor passes all W3C XPath 2.0 tests. I've checked your example with current Xerces SVN, and I don't find any bug wrt your example. I can see, that you use the xpathDefaultNamespace attribute on <assert> which may be causing issues. If you can post a complete XSD schema document along with an XML instance document, we could debug better.
