[Zope] dtml result in href

another question. when I create a link with a filename and url from a database. I do it like this: <a href="<span tal:conent="result/url">url goes here</span>"> <span tal:conent="result/filename">filename goes here</span> </a> this results in a link named as the true filename for ex: filename.txt but the link sends me to mysite/<span tal:conent="result/url">url goes here</span> instead of: mysite/subdir/filename.txt is there another way or another syntax to put de dtml in the href? thanks, Olivier
