Listmodel is a Python library for object mappings for various list sources (XML documents, CSV documents, text documents, JSON/YAML objects) in a unified manner.

Project description

Listmodel is a Python library for object mappings for various list sources (XML documents, CSV documents, text documents, JSON/YAML objects) in a unified manner. Inspiration was taken from QML XmlListModel.

Basic usage

>>> from listmodel import XMLDoc, QueryAttr, set_name
>>> xml = u"""<bookshelf>
...         <name>My Bookshelf</name>
...         <book>
...             <title>1984</title>
...             <author>Orwell, George</author>
...             <isbn>978-0-452-28423-4</isbn>
...             <chapter id="1">...</chapter>
...             <chapter id="2">...</chapter>
...             <chapter id="3">...</chapter>
...         </book>
...         <book>
...             <title>The man in the high castle</title>
...             <author>Dick, Philip K.</author>
...             <isbn>0679740678</isbn>
...             <chapter id="1">...</chapter>
...             <chapter id="2">...</chapter>
...             <chapter id="3">...</chapter>

>>> class Bookshelf(XMLDoc):
...     class Iterable(XMLDoc):
