[Zope] test for the existence of a nodeValue

[Jon Bowlas]

Hi All,

 

I'm pretty new to python and zope but would like to know how I can adapt
this script below to test to see if nodeValue actually contains a value and
if it doesn't then I would like to return a default value I can check for
using my zpt that references this script:

 

if not attobject:

    return ''

version = attobject.get_viewable()

nodes = version.content.documentElement.getElementsByTagName(attname)

if not nodes:

    return ''

return nodes[0].childNodes[0].nodeValue

 

Two parameters are passed to this script attobject, attname. 'attobject' is
an object id and 'attname' is the childNode with the nodeValue I wish to
return.

 

Hope someone can help, and I hope this makes sense.

 

Thanks

 

Jon
