try something like: <untested> <dtml-var "_[style_sheet].absolute_url()"> </untested> Phil phil.harris@zope.co.uk ----- Original Message ----- From: "John Morton" <jwm@plain.co.nz> To: "zope" <zope@zope.org> Sent: Wednesday, May 10, 2000 9:34 AM Subject: [Zope] Soft References in DTML

I'm constantly running into this general problem in DTML - how do I access an object or property who's name is given in a string?

Here's a specific problem:

I've got a Zclass product that has a string property in a sheet that's supposed to hold the name of the prefered cascading style sheet used when rendering the object. The name is automatically added to the header of the html doc when rendered, like this:

<link href="<dtml-var style_sheet>" ...>

But the style sheet itself lives a few directories down from the document being rendered so I really want the absolute URL. If I could act the object I could do <dtml-var "css_object.absolute_url()"> - but the name css_object (or whatever) is the value of the string style_sheet.

So how can I dereference the string?

Thank, John
