[Zope] Render a string as tal

[Alan Warren]

Hi,

I'm not sure I entirely understand the goal here either, but you may
want to look into the path method.

Here's what I recently had to use it for.

I'm building a little photo album application for my sister, it
supports nested albums.  I had a page template called view I was using
as a method, but wanted to logically group the actions specific to a
single image into a folder.  So, I have a folder called view.  When an
image is viewed the URL looks like
/some_album/some_pic.jpg/view/?display=large

If I want to do operations or locate properties on some_pic.jpg I
extract that part of the URL, and then pass it to the path function.

The code looks like this:
<span tal:define="imgName python:request['URL2'][len(request['URL3']+1:]">
    <span tal:define="global imgObj python:path('here/'+imgName)"></span>
</span>

HTH,
Alan
