Hi;

I'm using Saxon83 to invoke an Xquery expression. In my scenario I need to pass in a DOM element from another document that has already been parsed as the context node for the query. The DOM Element I need to set as the query context is some node in a large DOM tree that my function is being passed by another component. I have to just execute the query with the supplied DOM Element as the context, and return the result as a DOM Document.

Ideally, I'd like to be able to set the query context node using DynamicQueryContext.setContextNode(org.w3c.dom.Element), but of course setContextNode() only accepts a NodeInfo object.

Calling StaticQueryContext.buildDocument(Source) seems to be the only way to turn a DOM object into a NodeInfo, but this approach is not appealing to me as it returns the DOM Document object, not the DOM Element I was supplied. In other words, once I call buildDocument() I have no way of getting back to the original DOM Element (somewhere in that tree) I was interested in.

What I'm hoping is that there is some way of calling a buildDocument() like function that accepts a DOMSource but always returns me the NodeInfo representing the equivalent of the node returned by DOMSource.getNode().

Thanks in advance for any assistance,

Brian.
