===================== About GeneralMarshall
GeneralMarshall is a package for manipulating XML. It is comprised of an
abstract class that should be subclassed for usage.
GeneralMarshall is released under the GNU Greater Public License. Feel free
to reuse or distribute it in any way you see fit. I would appreciate
being notified <Daniel.Lee@dwd.de>_ if you use the library and/or have any
feature requests or suggestions.
The class makes extensive use of an overriden
__setattr__ in order to allow XML tag values to be set with a pythonic
programming interface. In order to make this possible, the XML file's tag
heirarchy must be defined in the subclass that implements
This is done by setting the private class attributes
When the subclass knows the possible structure of XML files it should use, the interaction can look like this::
import general_marshall class MyXML(general_marshall.XML): ... # Load XML file xml_object = MyXML("file_name.xml") # Print pretty printed XML to stdout print(xml_object) # Create empty XML object new_xml = MyXML() # Set a tag value, creating parent nodes if necessary new_xml.value = "something" # Export to file new_xml.export("output_file.xml")
lxml is used to interface with the XML file that is either read or
created, not all of the functions that
GeneralMarshall would profit from
lxml most are used in order to maintain compatibility with Python's builtin
xml library. This is due to the fact that
GeneralMarshall is used in
some places where
lxml is not available.
