[Zope] DTML, Zope and Regex

[Jorge O. Martinez]

Hi Zopers:

I am trying to do some very basic pattern matching, but to my surprise Zope 
does not seem to support it very well now (or I have not been able to find the 
right docs). I found a couple of items from Runyaga in ZopeZen and ZopeLabs 
regarding regexes:

<http://zopezen.org/SDot/993647662/index_html>
<http://www.zopelabs.com/cookbook/993591088>

The above postings are old (about 1 year), and I wonder if there's better 
support for regexes now...? Where can I look? What I want to do is awfully simple:

I have a folder object with other objects (pictures, html docs, etc.) which I 
want to traverse, and based on the object id's (file names are a string 
consisting of date + obj type, for example: 2002_July_08_pic_1.jpg), I want to 
  group them, and print headers for each group, for example:

Photos for July 7
<dtml-if expr="id =~ /2002_July_7/">  <- Just a 'perlarized' example
   <img src="&dtml-id;">
<dtml-if>

Photos for July 8
<dtml-if expr="id =~ /2002_July_8/">  <- Just a 'perlarized' example
   <img src="&dtml-id;">
<dtml-if>

I know I could go to properties, and add some kind of properties to each 
object, but that is not possible as I have lots, and it would be to hard to go 
TTW to add some property to each one of them....Or should I just give up DTML 
in this case? Any idea is welcome.

Thanks!,

Jorge M.
