Hi, I just learned about the XML-dtml notation for inserting values inside XML-strings.
I find this useful, and use it both in HTML and XML.
But, isn't there a way to supply a default value (if the variable lookup fails)?
Something like &dtml-variable default-value;
I think that would be stretching the semantics of <dtml-var> a bit beyond where they should go. Just wrap the entity in a <dtml-if> and test for the variable existence beforehand. Longer, but much more clear.
Would something like this be more palatable? <dtml-var foo default="Empty"> Chris -- | Christopher Petrilli Python Powered Digital Creations, Inc. | petrilli@digicool.com http://www.digicool.com
