Subject: [xsl] order by in XPath 2.0 expression? From: "Darcy Parker" <darcyparker@xxxxxxxxx> Date: Thu, 25 Sep 2008 15:42:37 -0400 |
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
