如何将 Saxon XdmNode 转换为 XmlDocument？

Question

I have a fully populated XdmNode and need to create an XmlDocument from it. How can I do that?

Answer 1

It's possible that the XdmNode is already a wrapper for an XmlDocument , in which case you can dive down through the wrappers to extract the underlying XmlDocument using XdmNode.getUnderlyingXmlNode() .

On the other hand, in the general case, you will need to copy the data across. The easiest way to do this is probably to run the XQuery "." using XQueryEvaluator.Run() with a DomDestination as the supplied XmlDestination ; on completion, DomDestination.XmlDocument gives you the DOM document node.

If you're constructing the tree using an XSLT transformation or XSD validation, then you can supply a DomDestination as the output for that process, in which case you can avoid the copying process.
