YAXI

Yet Another Xml Interface; terse queries using slices and calls with no deps.

For cases when your XML documents keep changing with no regard for rhyme, reason, or precedent, and you just want to pull out the right pieces of data.

Installing

Requires python>=3.6.

pip install yaxi

Developers can install an editable copy using flit install --symlink.

Examples

yaxi.YaxElement is just a subclass of builtin xml.etree.ElementTree.Element, so the right hand side of the below examples is just the equivalent xml module command:

import xml
from yaxi import
>>> x['What'] == x.find('What')
True
>>> x['What']['Param':] == x.find('What').findall('Param')
True
>>> x['What']['Param':('name',):'FAR'] == \
...     [p for p in x.find('What').findall('Param')
...      if p.get('name') == 'FAR']
True

You can also combine multiple indexing operations into a single attempt:

>>> x['What', 'Param':('name',):'FAR', 0] == \
...     [p for p in x.find('What').findall('Param')
...      if p.get('name') == 'FAR'][0]
True

For inconsistent XML that might match one of multiple schemas, you can Attempt to get the data from multiple locations and only raise an error if none of them work:

>>> x.attempt['aefpqiefd', 2:, 0] \                     # will fail
...          ['What', 'Param':('name',):'FAR', 0] \     # 1st success, returned
...          ['Foejqnfd'].get() == \                    # ignored
...     [p for p in x.find('What').findall('Param')
...      if p.get('name') == 'FAR']
