I used <xsl: sort select="number"> in my xsl file.
I used an empty tag <number></number> in my xml file.

I understand that sorting on an empty xml tag is very difficult but i didn't expect the xslt_process function to hang.

Of course where <number></number> is filled in everything works fine.

It should be better to give an error or place the empty tags in the beginning or in the end. Hangup cost server performance i think.

With kind regards,

Paul van Gils

Is this reproducable with sabcmd?

If not, please provide sample files. If they're long, post a url where they can be downloaded.

Thanks for your reply.
I made a script to reproduce the problem. 
On php version 4.2.1 on windows it works fine.
On php version 4.3.0 on linux it will hang.


With kind regards,

Please also report the Sablotron version you're using and whether wchar.h is present on your system?
 [2003-02-10 18:16 UTC] p dot vangils at mycoweb dot nl 
I'm using Sablotron version 0.97.

I don't know if wchar.h is present on my system because the error occured on the machine of my ISP.
 [2003-02-10 19:08 UTC] msopacua@php.net 
If you're using Sablotron 0.97 there should be a section on how Sablotron was configured in phpinfo() output.

Could you paste that as well as the output of the 'Configure command'? There's something really off here, since neither ilia nor me can reproduce what you're seeing, on totally different systems. Could you confirm if the ISP is WideXs (I might be able to get a shell on such a box then)?
