This packages is used to implement Zope's DTML objects (these objects add persistence which you do not need). One of the source files, I think it was "DocumentTemplate.DT_String" contains a good source documentation which tells you how to use DocumentTemplate in your Python code.

Re: [Zope] Dynamically render DTML?
Thanks too all who replied, I may have simplified my problem a little too much before posting it. The heart of it is that I'd like to have the Zope evaluate an arbitrary string as if it were a DTMLMethod For those interested, here is what I ended up doing... -- pyfile.py from OFS.DTMLMethod import DTMLMethod class myclass: """ a callable object: This is acting as a base class for a ZClass """ def __call__(self,REQUEST): """a callable object - I pass in REQUEST because my dtml-vary seems to require it """ # create your dtml string - note: the idea is, this doesn't have to be a static string... text= '\ ENGLIS TITLE\ THIS IS ENGLISH CONTENT\ \ THSI IS FRENCH CONTENT\ \ Spanish title\ This is spanish text\ ' met h=DTMLMethod() # populate the DTMLMethod meth.manage_edit( text,'THIS IS THE TITLE') #the DTMLMethod goes out of scope here, so it's never persistent ( I hope ). return meth(REQUEST) -- I call this from from zope as follows... - m1 is an instance of a ZClass that has myclass as a base class. this calls myclass.__call__(self,REQUEST) - This solution worked for me. It would still be nice if I didn't have to pass REQUEST explicitly. I could have derived myclass (or the ZClass) from DTMLMethod, but I didn't need the DTMLMethod itself to be persistent. Also, I'm not sure how to intercept __call__ and pas it on to the DTMLMethod. It's a little ugly, but it works. It would be nice to be able to just say in zope and have it render.

As a follow-up, is it possible to evaluate DTML that is returned from an SQL Query? -Magnus ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

to clarify on the python solutions, the options that i see are either
1. calling the dtml method. if you have a reference to the method than
you call it directly. something like
return standard_html_header()
refer to lib/python/OFS/DTMLMethod.py for calling syntax & args
2. evalutate an arbitrary dtml string ala '', something like
return HTML('')()
refer to lib/python/OFS/DocumentTemplate/ for exact syntax && args.

[Zope] Dynamically render DTML?
Is it possible to return dtml from python, and have it rendered correctly on the page? for example, the python might look like this... def get_header(somevar=1): if somevar==1: return '' else: return '' The dtml document in the zodb might look like this... Body text When this gets rendered, it's as if the dtml document had in place of the get_header call. I understand how to call external methods from dtml, etc. I just want to know if it's possible to get the string returned rendered as dtml.
