Can Saxon-JS process a HTML DOM document with a DOCTYPE node?

Added by Martin Honnen over 2 years ago

I tried to fed a HTML document in the browser to Saxon-JS 2.3, it seems if the document has a DOCTYPE node (from e.g. <!DOCTYPE html>) then Saxon-JS (at least during an identity copy) bails out on the "node kind 10" with e.g.

code: "SXJS0003" message: "Unknown node kind 10"

What does that error message mean, does it come from the serializer of Saxon-JS? Or is the XSLT processing failing due to the DOCTYPE node in the tree? If so, shouldn't Saxon ignore it?

Sample is at https://martin-honnen.github.io/xslt/2022/replaceChildrenTest1.html, after using the button Chrome console shows

Yes, if there's a DOCTYPE node present in the DOM then we should ignore it, and on some paths we do -- you've obviously found a path where we don't. Is this XML supplied as source to the parser, or programmatically constructed?

If we can reproduce it then it should be easy enough to resolve.

It is the browser's HTML DOM document of the main browser window, so it is the browser's HTML parser that created the HTML DOM document and I feed it to the Saxon-JS APIs.

The error is the same if the browser parses an XHTML document (loaded in a browser window) with its XML parser: https://martin-honnen.github.io/xslt/2022/replaceChildrenTest1.xhtml:

Another test using SaxonJS.transform({ sourceLocation : 'someXMLWithDoctype.xml', ...}) also fails: https://martin-honnen.github.io/xslt/2022/doctypeParsingTest1.html:
