I find the following works well for me to provide a list of webpage

with hyperlinks
<ul>

<a tal:content="item/title" tal:attributes="href item/

What I would also like to do is provide an empty entry if there are no
webpage titles in the database. For example:
<ul>
<li>
No titles found.
</li>
</ul>
I'm confident PHPTAL can do this, but there are so many options that
look as
though they might do the trick I'm not sure where to start.
Can anyone advise me?
In PHPTAL empty array evaluates to false, so this works:
<p tal:condition="not:titles">No titles found.</p>
<ul tal:condition="titles">
...
If you want an empty list item:
<ul>
<li tal:condition="not:titles">No titles found</li>
<li tal:repeat="item titles">
<a tal:content="item/title" tal:attributes="href item/
href">title
is missing</a>
</li>
</ul>
