Using zope.pagetemplate. ;) More seriously, zope.pagetemplate has two parsing modes: HTML and XML. Nobody actually uses the XML mode (pt files start with an <?xml?> declaration, all tal/metal namespaces must be explicitly defined using xmlns:tal=url-that-nobody-can-remember). The HTML mode allows you to write Javascript just like you would do it in a browser, with no extra XML-quoting: <script type="text/javascript> if (1 < 2) alert("it works!"); </script> Does this not work for you? I'm currently looking at a Zope3 app that does precisely this in its working page templates. > I need to insert a <script> tag with Javascript in it.

Which I did, and when the template was rendered the > data was still xml escaped and again invalid javascript. I think scripts in XHTML were supposed to be XML-escaped. AFAIU zope.pagetemplate was designed back when XHTML was supposed to be The Bright Future of the Web. Marius Gedminas -- Always proofread carefully to see if you any words out.
