Update, that issue @Lx linked 404's now. Here's the updated URL: cmprescott/ansible-xml#14

This is very nice, any example how can we take a specific attribute or value from the xml?
EG <Site Name="MySite"> Loading time</>
We would like to get the site name.
Thank you!

You wouldn't happen to have a version that is compatible with version 2.0 of Ansible would you?

I created a version for Ansible 2.0 based off of yours that should function the same: https://gist.github.com/danieldbower/7b34c45ad5e39576e2e5

in case some one want to perform lookup using ansible-xml

- name: playing with ansible xml
    xml:
      path: /root/akhil/config.xml
      xpath: //name[text()='hive.cli.print.header']/../value
      content: text
    register: header_value
   
  - name: debug hits
    debug:
      msg: "var hits = {{ header_value.matches[0].value }}"
