[ZPT] escaping chars in tal

[Thomas Olsen]

Hi I'm trying to set the attributes in a meta tag. I have tried:

<meta http-equiv="refresh" content="dummy" tal:attributes="content
python:('%s; URL=%s' % (here.refreshrate, here.absolute_url()))">
<meta http-equiv="refresh" content="dummy" tal:attributes="content
string:python:('%s%s%s' % (here.refreshrate, '; URL=',
here.absolute_url()))">
<meta http-equiv="refresh" content="dummy" tal:attributes="content
python:('%s; URL=%s' % (here.refreshrate, here.absolute_url()))">

and other variation of this but to no avail. Every time there is a semi
colon or an equality sign in the expression Zope barfs saying something
like:
Products.PageTemplates.TALES.CompilerError: invalid variable name
"absolute_url()))"

If I try without the semi color or equality sign it works OK?
