I have a template that looks like this, that displays widget content from an RSS feed:
<% control GetBlogPosts %>
<p>
<a href="$URL" alt="Read $Title" target="_plain" >$Title</a><br>
$Body
</p>
<% end_control %>
Where the $Body is, I would like to only display 100 characters of the body that is returned by the control. My question is should I truncate the field in the widget or is there a way to do this in the templating engine?
Thanks in advance for your help.
You can't do that in the template system. No programming aspects can be used in it, it is meant to go in your controller or page types.
Can you change the type of $Body to HTMLText? Then you can use the defined methods for this type (e.g. $Body.LimitWordCount(100))

Otherwise there is no chance :-)
