[Zope] Parsed XML Problem (we may need the best minds to solve this one :-)

[Adam Warner]

Hi all,

I'm calling an external method with this DMTL:

<dtml-var "db2onehtml(_.getitem('test.xml'))">

Which works fine so long as I upload "test.xml" as a _file_.

If I upload test.xml as Parsed XML I instead receive this error message:

Error Type: TypeError
Error Value: call of non-function (type string)

It appears Parsed XML items in the Zope database are not objects like
files.

http://www.zope.org//Wikis/DevSite/Projects/ParsedXML/ParsedXMLIsNotXMLObject

I want to be able to treat Parsed XML as an object. I hope someone can
give me a clue where to proceed. I also tried calling a python method
which took the XML data from the Parsed XML and converted it to a
string. I then tried feeding my external method with the string. But I
just receive this error message: 'string' object has no attribute 'id'
