HTTPResponse.insertBase does not detect multiline base tags

[Stefan Bunse]

My PageTemplates generate a multiline base tag which is not detected by the HTTPResponse so it adds a second base tag which in turn is invalid xhtml.

the corresponding regex is in ZPublisher.HTTPResponse, line 474:

  base_re_search=re.compile('(<base.*?>)',re.I).search

to make it detect my multiline base tag i changed it to:

  base_re_search=re.compile('(<base[^>]*?>)',re.I|re.M).search

and it works.

Why do you have to generate the BASE tag on your own. There is usually absolutely no need to do anything with the BASE tag. This is up to Zope!

my main template contains the navigation (with flash movies) and an iframe tag which loads the actual content. to make all links target the iframe i want to send <base href="#" target="content-frame" />.
but i found no (clean) way to make tal render the whole tag on one line and imho it's valid (x)html to spread a base tag over multiple lines.

This bug is related to ZPublisher, not ZServer.
