[Zope] another simple one

[Eric Walstad]

Hi Rick,

I think that something like this will work for you:
<dtml-call expr="REQUEST.set('ListContainingSplitItems', 
_.string.split(VariableNameToSplit, '-')">

This sets a variable in the REQUEST dictionary by first calling the 
split function of the string module.  The ListContainingSplitItems 
variable will contain the results of your call to split().  The 
"VariableNameToSplit" variable is the one that contains the "108243-132" 
string.
Then you can iterate through your split items with
<dtml-in ListContainingSplitItems>
     <!-- Do something useful here -->
     Item #<dtml-var sequence-index> is <dtml-var sequence-item>
</dtml-in>

Search the archives or look in your Zope book for info on "_" (the 
underscore), which has special meaning in Zope.

I would recomend that you do this sort of thing with a Python Script 
instead of DTML.  I think it's cleaner than the messy DTML above.

Script (Python) Id = split_on_hyphen
parameters VariableNameToSplit
import string
return string.split(VariableNameToSplit, '-')

Then your dtml would look like this:
<dtml-in "split_on_hyphen(VariableNameToSplit)">
     <!-- Do something useful here -->
     Item #<dtml-var sequence-index> is <dtml-var sequence-item>
</dtml-in>

Hope that helps,

Eric.
