[Zope] Help with expr

[Eric Walstad]

Hi Todd,
Id suggest you grab a copy of the Zope book!
Check out:
http://www.zope.org/Members/michel/ZB
It comes in many different formats, but the printed version from your local
bookstore will help support a couple of nice resources :)

Here's what I found on page 63:
<table>
<dtml-in expr="objectValues('File')">
<dtml-if sequence-even>
<tr bgcolor="grey">
<dtml-else>
<tr>
</dtml-if>
<td>
<a href="&dtml-absolute_url;"><dtml-var title_or_id></a>
</td></tr>
</dtml-in>
</table>

The key bit here is the <dtml-if sequence-even> block.  Add a <dtml-else>
block if you need to specify a second color.

Happy Zoping!

Eric.
