xpath error in selectPath? "Path must select only elements and attributes"

[Dm...@toyota.com.au]

hey all,
 
not sure if this is my lack of understanding, or a limitation in xmlbeans,
or something completely different.  running xmlbeans from bea that shipped
with 8.1SP2.
 
Consider the following code:
 
 public static void main(String[] args) throws Exception
 {
  XmlObject xml =
XmlObject.Factory.parse("<foo><bar>0001237843</bar></foo>");
//  String text =
xml.selectPath("./foo/bar")[0].newCursor().getTextValue();
  String text =
xml.selectPath("./foo/bar/text()")[0].newCursor().getTextValue();
  System.out.println("text = " + text);
 }
 
the commented out line works fine.  However, the code as it stands throws
the following exception:
 
com.bea.xml.XmlRuntimeException: Path must select only elements and
attributes

I had assumed that I'd be able to bang a /number() on the end of my xpath
and trim the leading 0's (damn SAP).  Is this a real limitation?  From the
xpath spec I get the impression the above is legal...
 
alternatively, if someone could tell me an easy way of making selectPath
trim the leading 0's that'd be great (o:
