[Zope] Removing part of a string (in an URL)

[Walter A. Aprile]

Hi,
	more newbie questions, I am afraid. I have a ZCatalog result form
that boringly forms links this way:

<dtml-var "busca.getpath(data_record_id_)">

	Due to the way my site is organized, the URL I get has an unwanted
part at the beginning. The part is always the same size, and the same string
in fact. How do I remove it ? For example, the URL is

http://zorba.com.mx:8080/Zorba/busca/Zorba/cacharrito/prueba
                                    ^
and I would like to cut it here     |
and turn it into 

/Zorba/cacharrito/prueba

	The problem is that the URL above is still valid, but if I do another
search then the same /Zorba/busca gets added, and it gets longer and longer,
besides messing up my breadcrumb trail.

	I tried using a regular expression method, but I do not really know
Python (not yet !), so it did not work. 

	Thank you very much
				Walter
