[Zope] stupid question: first 7 chars of an URL

[schoppa@uni-bielefeld.de]

Hi there,

can't figure out how to write the frist 7 characters of an URL string to a new
var.

<dtml-var urlvar[0:4]> works fine. 
<dtml-var urlvar[0:7]> doesn't work.

<dtml-if "urlvar[0:7] == 'http://'">


The problem is the ':'. May be one have to use url_quote. But can't combine 
dtml-let drml-call with url-quote to create a new var.

Thank you
Marcus
