Fixes #89: Remove bug from xmlToJson method.

Previously, our xmlToJson method was returning error:
Global name "fromstring" is not defined.
cause it is method of lmxl.etree and should be called
using lmxl.etree object.

This commit fixes this issue.
- Import lmxl.etree module and then call method "fromstring".
- Add lmxl dependency in requirements file.
