We won't allow PHP code in the templates by default, however you could write a template function which executes whatever is present as it's children.
Another approach to this is to have an xmltree operator which generates the xml dom tree and returns it. That way it's possible to go trough the tree to get the data you need.
A third option is to have an XSLT operator which would transform the xml into html according to an xslt file.
The two last solutions might be included in the standard release in the future, but we cannot guarantee when it will happen (if it will happen).

Seems the most logical way now, useful for small xml objects

We need it too, the XSLT operator I mean. And we will write a module for it if necessary, probably in the next 6 months after 3.0 final. It is desirable for incorporating external XML content: through SOAP enabled services for example, or even better to get Docbook XML support. There are basically two options: do everything with php libraries or let a backend do the transformations (apache cocoon for example, it would also handle the caching of results). Any comments?

That appears to be trivial, why not set $buf as a single variable in a template which surrounds this by <div ....> </div> ?

No, it is the other way around: you set the values of a variable in the template through a php script.
To call php code (in a module) from a template, the "fetch" template function should be used as far as I understand. In any case this php code should then fill a template.

The usual way is to set template variables from the PHP before the template is executed. $tpl->setVariable( "buf", $buf );
or you can create custom template functions and/or operators to do the work.
The fetch system can be used to execute functions in a class, see kernel/content/function_definitions.php for some examples.
Also the PHP operator defined in lib/eztemplate/classes/eztemplatephpoperator.php can be used to map php functions to template operators easily, create your own custom functions in PHP and map them with this class.
