Z:d@ Z; eZZ> e>ee y# e?$ r Y yw xY w)Fa Lightweight XML support for Python.
XML is an inherently hierarchical data format, and the most natural way to
represent it is with a tree. This module has two classes for this purpose:
1. ElementTree represents the whole XML document as a tree and
2. Element represents a single node in this tree.
Interactions with the whole document (reading and writing to/from files) are
usually done on the ElementTree level. Interactions with a single XML element
and its sub-elements are done on the Element level.
Element is a flexible container object designed to store hierarchical data
structures in memory. It can be described as a cross between a list and a
dictionary. Each Element has a number of properties associated with it:
'tag' - a string containing the element's name.
'attributes' - a Python dictionary storing the element's attributes.
'text' - a string containing the element's text content.
'tail' - an optional string containing text after the element's end tag.
And a number of child elements stored in a Python sequence.
To create an element instance, use the Element constructor,
or the SubElement factory function.
You can also use the ElementTree class to wrap an element structure
and convert it to and from XML.

This class is the reference implementation of the Element interface.
An element's length is its number of subelements. That means if you
want to check if an element is truly empty, you should check BOTH
its length AND its text attribute.
The element tag, attribute names, and attribute values can be either
bytes or strings.
*tag* is the element name. *attrib* is an optional dictionary containing
element attributes. *extra* are additional element attributes given as
keyword arguments.

Z y)r a8 Generic element structure builder.
This builder converts a sequence of start, data, and end method
calls to a well-formed element structure.
You can use this class to build an element structure using a custom XML
parser, or a parser for some other XML-like format.
*element_factory* is an optional element factory which is called
to create new Element instances, as necessary.
*comment_factory* is a factory to create comments to be used instead of
the standard factory. If *insert_comments* is false (the default),
comments will not be inserted into the tree.
*pi_factory* is a factory to create processing instructions to be used
instead of the standard factory. If *insert_pis* is false (the default),
processing instructions will not be inserted into the tree.

If *out* is provided, it must be a file or file-like object that receives
the serialised canonical XML output (text, not bytes) through its ``.write()``
method. To write to a file, open it in text mode with encoding "utf-8".
If *out* is not provided, this function returns the output as text string.
Either *xml_data* (an XML string) or *from_file* (a file path or
file-like object) must be provided as input.

Canonicalization writer target for the XMLParser.
Serialises parse events to XML C14N 2.0.
The *write* function is used for writing out the resulting data stream
as text (not bytes). To write to a file, open it in text mode with encoding
"utf-8" and pass its ``.write`` method.
Configuration options:
- *with_comments*: set to true to include comments
- *strip_text*: set to true to strip whitespace before and after text content
- *rewrite_prefixes*: set to true to replace namespace prefixes by "n{number}"
- *qname_aware_tags*: a set of qname aware tag names in which prefixes
should be replaced in text content
- *qname_aware_attrs*: a set of qname aware attribute names in which prefixes
should be replaced in text content
- *exclude_attrs*: a set of attribute names that should not be serialised
- *exclude_tags*: a set of tag names that should not be serialised
