[Zope] inelegant repetition of ZPT code

[Andre Meyer]

Hi Zopers

Another detail that bugs me: how can I translate the following dtml code
to zpt. It colours table rows in grey/white alternatively. Is the zpt
version below the only way? It is clearly very inelegant to repeat code.


DTML

...
<table>
    <dtml-in listItems>
        <tr <dtml-if sequence-even>bgcolor="lightgray"</dtml-if>>
            <td>...</td>
        </tr>
    </dtml-in>
</table>


ZPT

...
<table>
    <span tal:repeat="item here/listItems">
        <tr bgcolor="white" tal:condition="repeat/item/even">
            <td>...</td>
        </tr>
	<tr bgcolor="lightgray" tal:condition="repeat/item/odd">
            <td>...</td>
        </tr>
    </span>
</table>


thanks and best wishes
