[Zope] TAL conditional statement - newbie question

[Gautam Saha]

Thanks a lot Dieter, for your response.

I actually figure it out by looking at some codes and by using the 
template.getId()
as suggested by you.

Regards,

Gautam

Here is what I did if any one is interested:
===============  Code   in my news_slot.pt file ==============
<!-- Link to news Archive  from the News Slot -->

<p metal:define-macro="news_link">
    <span tal:condition="python:test(template.getId()!= 'news', 1,0)">
       <a href="news"
          tal:attributes="href string:$portal_url/news">
          <img tal:replace="structure here/linkTransparent.gif" />
        <span tal:omit-tag="" i18n:translate="news_archive">News 
Archive</span>

        </a>

    </span>

</p>
=============  End of Code  ==============
