As a follow-on to Philipp's comment about WSGI middleware: It could be fairly easy (to be sure, not *really* easy) to do a search-and-replace for link tags and do appropriate alterations in WSGI middleware. If I were doing this, I might re-parse the document in middleware using lxml, then do an xpath query to find the locations in the document that need changing. Then, it would be a matter of using the elementtree API to make the changes. lxml.etree.tounicode() would put the page back together for output. Since outgoing pages generated with ZPT are generally parseable, this might work OK. N.B., You may have to use the DTD at some point with this method. Lxml will attempt to xml-minimize (e.g., ) all tags without text content, so you will have to assure that this does not happen where it shouldn't. If you are not too married to generating pages with ZPT, and if you like the elementtree API, there is also a possibility of a lxml/elementtree (python-only) method for generating pages, which can have a method for post-processing the page, in a manner like the above, except that the document stays in a parsed state until it is output by Zope. I have a working base class for this. I call it XTemplate. It's not-quite-ready-for-prime-time (no docs or tests, yet, and you have to do skinning within this framework), but if there is interest, I should be able to release a preview in the near future. -Jim Washington ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Think also about the case when links are coming from HTML (possibly transformed from some other format?) inside some content object rendered via a view. Look at zope.contentprovider, though. It sets up the provider: namespace. It's fairly simple.
