to allow ad-hoc display of the source of any file, as well as a "directory listing" structure. - reorganize examples/ to take advantage of new extension. in particular, keep moving all the descriptive text for files etc. into module docstrings, taking more advantage of self-documentation.

Illustrates three strategies for persisting and querying XML
|
|
documents as represented by ElementTree in a relational
|
|
database. The techniques do not apply any mappings to the
|
|
ElementTree objects directly, so are compatible with the
|
|
native cElementTree as well as lxml, and can be adapted to
|
|
suit any kind of DOM representation system. Querying along
|
|
xpath-like strings is illustrated as well.
|
|
|
|
E.g.::
|
|
|
|
# parse an XML file and persist in the database
|
|
doc = ElementTree.parse("test.xml")
|
|
session.add(Document(file, doc))
|
|
session.commit()
|
|
|
|
# locate documents with a certain path/attribute structure
|
|
for document in find_document('/somefile/header/field2[@attr=foo]'):
|
|
# dump the XML
|
|
print document
|
|
|
|
.. autosource::
|
|
:files: pickle.py, adjacency_list.py, optimized_al.py
