For the Expression xo.selectPath("//[EMAIL PROTECTED]/@id]") I get an empty
result-array.
Doesn't the left- and the right-hand-side of that filter-expression
always refer to the same node, which would mean,
that the xpath-engine tries to select any nodes with
the two attributes @idRef & @id having the same value?

Siggi,
can you try
xo.selectPath("//[EMAIL PROTECTED]/@id]");
and see if that works?

Subject: selectPath with FilterExpression using $this
Hello,
for a given XmlObject xo with an ID-Attribute 'id',
I've tried to launch the following xpath-expression:
xo.selectPath("//[EMAIL PROTECTED]/@id]")
in order to get all nodes (with idRef-Attribute) refering to my node xo.
Unfortunatlly this expression seems not to work. I always get an
java.lang.ArrayIndexOutOfBoundsException from the underlying
net.sf.saxon.expr.XPathContextMajor.setLocalVariable(XPathContextMajor.j
ava:213)
At
http://xmlbeans.apache.org/docs/2.0.0/guide/conSelectingXMLwithXQueryPat
hXPath.html
I found the following notice:
"Notice in the query expression that the variable $this
represents
the current context node (the XmlObject that you are querying
from).
In this example you are querying from the document level
XmlObject."
After reading that sentence I've been thinking, that $this is somehow
similar to "curent()" in XSLT, but maybe a got the meaning wrong.
Does anyone know whats the problem here rsp.
is there a better way to accomplish the same thing?
Thanks a lot,
Siggi
