This is a straight reformat run using black as is, with no edits applied at all. The black run will format code consistently, however in some cases that are prevalent in SQLAlchemy code it produces too-long lines. The too-long lines will be resolved in the following commit that will resolve all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

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
