Hi,
I was just reading a document about XML databases and saw this
interesting XPath expression:
for $i in /bead order by $i/text/@lang return $i
(Source:
http://www.oracle.com/technology/products/berkeley-db/pdf/overview-of-berkeley-database-xml.pdf)
The meaning of it seems obvious - and useful. But I have never seen
"order by" in an XPath expression before. I had a look online. I
don't see anything about it in http://www.w3.org/TR/xpath20/ or in
Michael Kay's XSLT 2.0 and XPath 2.0 Programmer's Reference (4th
edition). As well, I tested using it in saxon and see that it is not
recognized...
Perhaps this is an Oracle extension...? Has anyone seen this in an
XPath implementation before?
Thanks
Darcy
