From xml data to python code to run

[ralfbrand50@gmail.com]

Hello,

I've got the following question:

Is it possible to run data that's from an xml file as python code, by
this I mean the following.

In a xml file there's the following data

<code><![CDATA[self.wTree.sign al_autoconnect( dic)]]></code>

Now I want to extract the self.wTree.sign al_autoconnect( dic)* from the
xml file and make it possible that Python runs this, instead of having
a python file were with the hardcoded self.wTre.. in it.

*this could my any sort of data, single or multiple lines, even whole
def's

Kind regards,

Ralf Brand

from elementtree import ElementTree as ET

text = """<doc><code>< ![CDATA[object.method(' hello')]]></code></doc>"""

doc = ET.fromstring(t ext)

class Object:
def method(self, value):
print value

# populate the namespace
namespace = {
"object": Object()
}

# execute all code fragments
for code_elem in doc.findall(".//code"):
exec code_elem.text in namespace
