README example (removing attribute) does not work. about ansible-xml

[cmprescott]

What's your system running? I just tested it and it worked with
OS X 10.10.1 (Yosemite)
Ansible version 1.8.4
lxml 3.4.2
python 2.7.9

CentOS 6.5
Ansible version 1.9.2
python-lxml 2.2.3-1.1.el6
Python 2.6.6

I have pulled commit 1f7d1c3 (from two days ago) and I still have the same problem.

Here is my playbook (running against another CentOS box in Vagrant)

---
- hosts: vagrant
  remote_user: vagrant
  tasks:
  - name: copy resources
    copy: src=files/test.xml dest=/tmp/test.xml
  - name: xml transform
    xml: file=/tmp/test.xml xpath=/business/rating/@subjective ensure=absent

Thanks @jgensler8 I'll try to recreate this weekend.

Sorry for long delay. I recreated what you see and found the issue.

lxml introduced attrname in 2.3 (http://lxml.de/3.4/changes-3.4.4.html#alpha1-2010-06-19). I'll make a note in the readme for minimum requirements.

Problem fixed itself after updating lxml doing the following

# http://stackoverflow.com/a/12896566/618580
sudo yum install libxslt-devel libxml2-devel gcc
# should be v3.4.4 after this
sudo pip install lxml --upgrade

Is this still an issue? The test works for me. Along with updating the readme about the new requirement this comment should also be removed https://github.com/cmprescott/ansible-xml/blob/master/tests/test.yml#L15.

@cmprescott,

Installing the packages you have listed has solved the issue! Thank you!

One note, you may want to change the README in the project to reflect that installing lxml from pip rather than the OS's package manager is preferred.

👍
