I'm having some trouble getting acquisition to work with XMLDocuments. When calling some part of an XML doc by URL acquisition works, but when calling it in Python it doesn't (or I don't get it). I get name errors.

Example:

XMLDocument - doc: <?xml version="1.0"?> <text>This is text</text>

DTML method - renderText: <p> <!--#var "text_content()"--> </p>

Hmm, why not <!--#var text_content-->

DTML method - viewText: <!--#var standard_html_header--> <!--#var "doc[0].renderText()"--> <!--#var standard_html_footer-->

Hmm. You are calling a DTML Method with no arguments. In general if you call a DTML Method explicitly you should provide a client and a mapping argument. Even better, don't call it explicitly, let DTML render it, <!--#with "doc[0]"--> <!--#var renderText--> <!--#/with-->

When I access renderText as follows, it works:

.../doc/0/renderText

However, when I use viewText instead, it gives a NameError (text_content unknown). So acquisition is in fact doing something (as renderText is indeed called), but then it seems to forget the namespace context?

Am I doing something wrong or is this a bug?

I think that you are doing something wrong. Check out the advanced DTML How-To, on DTML Method calling subtleties. http://www.zope.org/Documentation/HowTo/DTML Good luck! -Amos
