Siggi,
yes, I did mean that you could use execQuery() to run the
XQuery.
Sorry, but I don't have anything else useful to tell you.

Subject: Re: selectPath with FilterExpression using $this
Wing Yew,
I've tried the following function-call
XmlBeans.selectPath("let $cur := . return //*[idfRef=$cur/id]);
and got the following Error:
net.sf.saxon.xpath.StaticError: XPath syntax error at
char 1 in {
let $}: 'let' is not supported in XPath
Maybe you've been thinking about using
XmlBeans.execQuery(...)
My Problem with this approach would be that
XmlBeans.execQuery(...)
just delivers copies of the requested Nodes, isn't it?
Unfortunately that wouldn't fit my needs.
I can hardly believe, that I'am the only one,
who needs to select all nodes refering
to a given XmlBean (by IDREF-ID-Relation).
Thanks for your help, anyway!
Do you have any idea,
where I could get some further Information rsp.
who could give me some help about that matter?

It seems right.
