[Website] Summary tag

Hi,

I create my webpages with help of WebsiteDTD and I use on every page the 
summary tag. The stylesheets generate out of this an description for 
links in the menu. Nice, but If the text in the summary element contains 
newlines, the link description will also contain newlines and not needed 
spaces. At times some browsers misunderstand the generated description 
and show another char, which is similar to a box.  How can I remove 
newlines from the summary, so that they don't appear in the link 
description?

Bye
