Description

I am doing POC on SaxonCS (11.3.0) .net core to upgrade the legacy Saxon9he library with new SaxonCS 11.3.0.

I am using copy-of function in XSLT where expectation is copy the current node and all child nodes with namespaces but namespace were missing for some child nodes thus it generate error for us. Please have a look below error and suggest.

System.Xml.XmlException : 'qri' is an undeclared prefix. Line 2, position 5.

I have attached XSLT, input xml , Previous Output xml (Saxon9he library) and New Output xml (SaxonCS 11.3.0) for your reference

Thanks for reporting it.

How are you running the transformation: Command line or C# API? If the latter, how do you supply the input, and what kind of output destination do you use?

Running from the command line, and with the current 11.x development branch, I'm seeing a failure with different symptoms: it's failing with Saxon.Ejava.lang.IllegalStateException: Prefix qri has not been declared. The difference could simply be that in development we have extra internal checking switched on.

~~Succeeds on SaxonJ.~~

On SaxonJ (running without the extra checks in RegularSequenceChecker) it's producing output without the required namespace declaration. So the bug affects both SaxonCS and SaxonJ.

I am using C# API, we are supplying input in InitialContextNode property and for output we implemented ResultDocumentResovler. As you mentioned it succeeded in SaxonJ, does it mean there is an issue in SaxonCS 11.3.0?

I think the problem is with TinyTextualElement.copy(). The class TinyTextualElement is used for an element in a TinyTree that has no attributes, no namespace declarations, and single text node child: here <qri:QuoteRef>NEG000001KWU</qri:QuoteRef>. When this is copied with copy-namespaces="no", it's failing to pass on the namespace declaration for the element's name. The namespace declaration is output correctly for the qri:CustomerSpecificFields element, which isn't represented as a TinyTextualElement.
