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

[T. J. Mannos]

Walter,

Try a little trick I use with _.string.split().  split() splits a string into two (or more) parts based on a delimiter.  In this case, the delimiter could be any part of the URL directly to the left of /Zorba/busca/...

For example:
<dtml-var "_.string.split(url, ':8080')[1]">

This splits the URL into 'http://zorba.com.mx' (which you don't want) and '/Zorba/busca/Zorba/...' (which you do want).  The [1] tells Zope to take only the second part, the part you want.

If you plan to make this code portable incase you switch servers or use a SiteRoot, I believe (and correct me if I'm wrong) you're safer using the 'BASE0' property for your delimiter.  For example:

<dtml-var "_.string.split(url, BASE0)[1]">

Now, I don't know about the organizational problems that prevent you from dropping the /Zorba/busca, but I'd assume you would do the same thing, except replace "BASE0" with "BASE0 '/Zorba/busca'".  I'm thinking, though, you'll eventually want to set up a separate server and a SiteRoot so that your web address will be http://zorba.com.mx/Zorba/cacharrito/prueba -- right?

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
