ElementTree module
This module contains functions for manipulating HTML or XML element trees described by ElementTreeData::ElementTree, including conversion to and from Strings, and a basic templating system.
Exceptions
- ExpectedChar - Expected character missing parsing XML
- InputError - Input error parsing XML
- NotLazy - The item to evaluate is not a generator
- UnexpectedChar - Unexpected character found parsing XML
- UnexpectedEnd - Unexpected end of data parsing XML
