Tamino XQUERY - using xpath expressions in node formatting

Hi folks,

This is my first post on the forums. I’ve done a search to attempt to answer my own question but I’m having no luck.

My question surrounds the use of xpath functions whilst formatting the output from a Tamino XQUERY.

If I define the following XQUERY…

$enquiry in input()/enquiry

{substring($enquiry/enquiry-type, 1, 1)}

I get the following error from Tamino

INOXQE6358 - Function unknown
Function: substring

Is this just a case that some of the xpath functions have been reserved by tamino xquery syntax but not implemented ?

If so - when is tamino likely to support this ? I’m using version

The reason why I need to do this is to flattern/transform certain nodes of my documents right back at the database. One of the reasons for doing this is to save sending ‘bulky’ data over the network and also to massively reduce the complexity involved in my xsl stylesheets.

Any information or help would be greatly appreciated.

Hi folks,

bit more information.

I’ve just upgraded my Tamino to and the substring xpath function now works after the return part of the xquery. This is a great relief.

I will do a bit more experimentation and report back if I find anything else but i imagine most other xpath functions now work too.
