[GeoNetwork-devel] Transformationexception due to date:format-date

[Jeroen T. <Jer...@ge...>]

Hi Francois,
I have been running into this error for some time now, and need to fix  
it for a workshop on Friday. Te problem is the following:

When harvesting from a WMS server, the transformation of the  
capabilities document fails in GeoNetwork (at least on the Windows and  
OS X machines I have used). I've nailed it down to the function call  
date:format-date() that apparently can not be found. This is strange  
because Xalan actually supports it, also in the version we use. I  
haven't been able to find out what causes the error. For now I have  
committed a fix that will use the function if available, and otherwise  
only call the date:date-time() function that has no problems.

This is the culprit: <gco:DateTime><xsl:value-of select="date:format- 
date(date:date-time(),$df)"/></gco:DateTime>

It occurs in the files:

/web/geonetwork/xsl/conversion/OGCWxSGetCapabilitiesto19119/ 
OGCWxSGetCapabilities-to-19119.xsl
/web/geonetwork/xsl/conversion/OGCWxSGetCapabilitiesto19119/ 
OGCWxSGetCapabilitiesLayer-to-19139.xsl
/web/geonetwork/xsl/conversion/OGCWxSGetCapabilitiesto19119/ 
identification.xsl

And the fix is in trunk. Maybe you have a better idea of the cause and  
thus a better fix :-) At least my workshop doesn't fail now :-)

Ciao,
Jeroen
