[Zope] How to convert characters that have special meaning in HTML to HTML character entities

Hi All, I have a string that contains a <a href="http://www.mywebaddress.com">link</a> tag that I would like rendered as HTML when output but it only seems to render in the html page like this <a href="http://www.mywebaddress.com">link</a>; To replace the characters, I tried this in my TAL: <tal:block tal:define="d_stand row/STANDFIRST | nothing; d_stand_replaced_chars python: (str(d_stand)).replace('>','>');"> <p tal:condition="d_stand_replaced_chars" tal:content="d_stand_replaced_chars" /> </tal:block> But it converted the '>' I replaced with a '>' back to a '>' upon rendering the string in a html page. Any ideas how I can achieve this? Jon
