'_ElementStringResult' object has no attribute 'attrname'

[dagwieers]

When running the integration tests from this project on the Ansible CI framwork on CentOS-6 (with native lxml v2.2.3) we get the following error:

Couldn't delete xpath target: /business/rating/@subjective ('_ElementStringResult' object has no attribute 'attrname')

Here is the detailed output:

So the Ansible xml module requires at least lxml v2.3.0 for supporting the attrname attribute.

This is now fixed in the upstreamed module. (A proper error message is returned)
