Merci Sylvain, but I got a problem to your solution probably related to my
structure???
I absolutely agree with you and I started using JXPath, but unfortunetly I
haven't managed to get the JXTemplate jx:forEach 'end' 'begin' tags to work
with JXPath, nore the jx:macro??? which got me to jexl
my problem here is that , the jexl is in a forEach which is itself is
looping on a forEach, so my jexl call is relative to the first forEach
context.
******************************************
My doc is like this:
<rooms>
<room><desc maxoc="12">text0</desc></room>
<room><desc maxoc="5"/>text1</desc></room>
<room><desc maxoc="6"/>text2</desc></room>
<room><desc maxoc="9"/>text3</desc></room>
</rooms>
*****************************************
This is in my html_jx page:
<jx:forEach select="#{rooms/room}" varStatus="status">
<jx:macro name="tablerows">
<jx:parameter name="maxoc"/>
<jx:forEach begin="0" end="${maxoc}" step="1" varStatus="statoc">
<tr>
<td><script>${statoc.count}</script></td>
<td><script>${statoc.count*24}</script></td>
<td><script>${maxoc}</script></td>
</tr>
</jx:forEach>
</jx:macro>
<table>
<tbody>
<tablerows maxoc="${description.getAttribute('maxoc')}"/>
</tbody>
</table>
</forEach>
*************************************
So as you can see the jexl element I need is relative to each room, can
someone help me retreive the /rooms/room/description/@maxoc for each
room ??
Thanks
