[Zope] - Access to sequence-item?

[Andy Smith]

There may be a nicer way of doing it, but you can access the outerlist by
using _.namespace to insert the orignal value of sequence-item into the DTML
namespace as a new variable. In situations where you've got  '-' in your
name, you can always use _['sequence-item']

<!--#var standard_html_header-->

<!--#in "[ [1,2,3], [4,5,6], [7,8,9], ['foo','bar']]"-->
   <!--#with "_.namespace(outeritem=_['sequence-item'])"-->
   <!--#in sequence-item-->
      I am looping over : <!--#var outeritem--> and I've got to <!--#var
sequence-item--><BR>
   <!--#/in-->
   <!--#/with-->
<!--#/in-->
<!--#var standard_html_footer-->

Cheers,

Andy.
