Description

According to the XPath 3.0 specification, given the expression ($p = $q) where $p is untypedAtomic and $q is a QName, the comparison should be done after casting $p to a QName using the namespaces present in the static context. Instead, Saxon crashes:

java.lang.UnsupportedOperationException: Cannot validate a QName without a namespace resolver

See QT3 test case -s:prod-GeneralComp.eq -t:GenCompEq-22 (contributed by Saxonica)

  • Status changed from New to In Progress

A complete fix has been made on the 9.7 branch; this involves saving the namespace context for every general comparison, which is expensive. For 9.6 a partial fix is being committed for now as a patch; the effect of the fix is to make this situation a dynamic error rather than a crash.
