:mod:`xml.etree.ElementTree` --- The ElementTree XML API
========================================================
.. module:: xml.etree.ElementTree
:synopsis: Implementation of the ElementTree API.
.. moduleauthor:: Fredrik Lundh <fredrik@pythonware.com>
.. versionadded:: 2.5
The Element type is a flexible container object, designed to store hierarchical
data structures in memory. The type can be described as a cross between a list
and a dictionary.
Each element has a number of properties associated with it:
* a tag which is a string identifying what kind of data this element represents
(the element type, in other words).
* a number of attributes, stored in a Python dictionary.
* a text string.
* an optional tail string.
* a number of child elements, stored in a Python sequence
To create an element instance, use the Element or SubElement factory functions.
The :class:`ElementTree` class can be used to wrap an element structure, and
convert it from and to XML.
A C implementation of this API is available as :mod:`xml.etree.cElementTree`.

.. _elementtree-functions:
Functions
---------
.. function:: Comment([text])
Comment element factory. This factory function creates a special element that
will be serialized as an XML comment. The comment string can be either an 8-bit
ASCII string or a Unicode string. *text* is a string containing the comment
string. Returns an element instance representing a comment.
.. function:: dump(elem)
Writes an element tree or element structure to sys.stdout. This function should
be used for debugging only.
The exact output format is implementation dependent. In this version, it's
written as an ordinary XML file.
*elem* is an element tree or an individual element.
.. function:: Element(tag[, attrib][, **extra])
Element factory. This function returns an object implementing the standard
Element interface. The exact class or type of that object is implementation
dependent, but it will always be compatible with the _ElementInterface class in
this module.
The element name, attribute names, and attribute values can be either 8-bit
ASCII strings or Unicode strings. *tag* is the element name. *attrib* is an
optional dictionary, containing element attributes. *extra* contains additional
attributes, given as keyword arguments. Returns an element instance.
.. function:: fromstring(text)
Parses an XML section from a string constant. Same as XML. *text* is a string
containing XML data. Returns an Element instance.
.. function:: iselement(element)
Checks if an object appears to be a valid element object. *element* is an
element instance. Returns a true value if this is an element object.
.. function:: iterparse(source[, events])
Parses an XML section into an element tree incrementally, and reports what's
going on to the user. *source* is a filename or file object containing XML data.
*events* is a list of events to report back. If omitted, only "end" events are
2007-10-21 09:10:28 -03:00
reported. Returns an :term:`iterator` providing ``(event, elem)`` pairs.

.. note::
:func:`iterparse` only guarantees that it has seen the ">"
character of a starting tag when it emits a "start" event, so the
attributes are defined, but the contents of the text and tail attributes
are undefined at that point. The same applies to the element children;
they may or may not be present.
If you need a fully populated element, look for "end" events instead.
2007-08-15 11:28:01 -03:00
.. function:: parse(source[, parser])
Parses an XML section into an element tree. *source* is a filename or file
object containing XML data. *parser* is an optional parser instance. If not
given, the standard XMLTreeBuilder parser is used. Returns an ElementTree
instance.
.. function:: ProcessingInstruction(target[, text])
PI element factory. This factory function creates a special element that will
be serialized as an XML processing instruction. *target* is a string containing
the PI target. *text* is a string containing the PI contents, if given. Returns
an element instance, representing a processing instruction.
.. function:: SubElement(parent, tag[, attrib[, **extra]])
Subelement factory. This function creates an element instance, and appends it
to an existing element.
The element name, attribute names, and attribute values can be either 8-bit
ASCII strings or Unicode strings. *parent* is the parent element. *tag* is the
subelement name. *attrib* is an optional dictionary, containing element
attributes. *extra* contains additional attributes, given as keyword arguments.
Returns an element instance.
.. function:: tostring(element[, encoding])
Generates a string representation of an XML element, including all subelements.
*element* is an Element instance. *encoding* is the output encoding (default is
US-ASCII). Returns an encoded string containing the XML data.
.. function:: XML(text)
Parses an XML section from a string constant. This function can be used to
embed "XML literals" in Python code. *text* is a string containing XML data.
Returns an Element instance.
.. function:: XMLID(text)
Parses an XML section from a string constant, and also returns a dictionary
which maps from element id:s to elements. *text* is a string containing XML
data. Returns a tuple containing an Element instance and a dictionary.
.. _elementtree-element-interface:
The Element Interface
---------------------
Element objects returned by Element or SubElement have the following methods
and attributes.
.. attribute:: Element.tag
A string identifying what kind of data this element represents (the element
type, in other words).
.. attribute:: Element.text
The *text* attribute can be used to hold additional data associated with the
element. As the name implies this attribute is usually a string but may be any
application-specific object. If the element is created from an XML file the
attribute will contain any text found between the element tags.
.. attribute:: Element.tail
The *tail* attribute can be used to hold additional data associated with the
element. This attribute is usually a string but may be any application-specific
object. If the element is created from an XML file the attribute will contain
any text found after the element's end tag and before the next tag.
.. attribute:: Element.attrib
A dictionary containing the element's attributes. Note that while the *attrib*
value is always a real mutable Python dictionary, an ElementTree implementation
may choose to use another internal representation, and create the dictionary
only if someone asks for it. To take advantage of such implementations, use the
dictionary methods below whenever possible.
The following dictionary-like methods work on the element attributes.
.. method:: Element.clear()
Resets an element. This function removes all subelements, clears all
attributes, and sets the text and tail attributes to None.
.. method:: Element.get(key[, default=None])
Gets the element attribute named *key*.
Returns the attribute value, or *default* if the attribute was not found.
.. method:: Element.items()
Returns the element attributes as a sequence of (name, value) pairs. The
attributes are returned in an arbitrary order.
.. method:: Element.keys()
Returns the elements attribute names as a list. The names are returned in an
arbitrary order.
.. method:: Element.set(key, value)
Set the attribute *key* on the element to *value*.
The following methods work on the element's children (subelements).
.. method:: Element.append(subelement)
Adds the element *subelement* to the end of this elements internal list of
subelements.
.. method:: Element.find(match)
Finds the first subelement matching *match*. *match* may be a tag name or path.
Returns an element instance or ``None``.
.. method:: Element.findall(match)
Finds all subelements matching *match*. *match* may be a tag name or path.
Returns an iterable yielding all matching elements in document order.
.. method:: Element.findtext(condition[, default=None])
Finds text for the first subelement matching *condition*. *condition* may be a
tag name or path. Returns the text content of the first matching element, or
*default* if no element was found. Note that if the matching element has no
text content an empty string is returned.
.. method:: Element.getchildren()
Returns all subelements. The elements are returned in document order.
.. method:: Element.getiterator([tag=None])
Creates a tree iterator with the current element as the root. The iterator
iterates over this element and all elements below it that match the given tag.
If tag is ``None`` or ``'*'`` then all elements are iterated over. Returns an
iterable that provides element objects in document (depth first) order.
.. method:: Element.insert(index, element)
Inserts a subelement at the given position in this element.
.. method:: Element.makeelement(tag, attrib)
Creates a new element object of the same type as this element. Do not call this
method, use the SubElement factory function instead.
.. method:: Element.remove(subelement)
Removes *subelement* from the element. Unlike the findXYZ methods this method
compares elements based on the instance identity, not on tag value or contents.
Element objects also support the following sequence type methods for working
with subelements: :meth:`__delitem__`, :meth:`__getitem__`, :meth:`__setitem__`,
:meth:`__len__`.
Caution: Because Element objects do not define a :meth:`__nonzero__` method,
elements with no subelements will test as ``False``. ::
element = root.find('foo')
if not element: # careful!
print "element not found, or element has no subelements"
if element is None:
print "element not found"
.. _elementtree-elementtree-objects:
ElementTree Objects
-------------------
.. class:: ElementTree([element,] [file])
ElementTree wrapper class. This class represents an entire element hierarchy,
and adds some extra support for serialization to and from standard XML.
*element* is the root element. The tree is initialized with the contents of the
XML *file* if given.
.. method:: _setroot(element)
2007-08-15 11:28:01 -03:00
Replaces the root element for this tree. This discards the current
contents of the tree, and replaces it with the given element. Use with
care. *element* is an element instance.
2007-08-15 11:28:01 -03:00
.. method:: find(path)
2007-08-15 11:28:01 -03:00
Finds the first toplevel element with given tag. Same as
getroot().find(path). *path* is the element to look for. Returns the
first matching element, or ``None`` if no element was found.
2007-08-15 11:28:01 -03:00
.. method:: findall(path)
2007-08-15 11:28:01 -03:00
Finds all toplevel elements with the given tag. Same as
getroot().findall(path). *path* is the element to look for. Returns a
list or :term:`iterator` containing all matching elements, in document
order.
2007-08-15 11:28:01 -03:00
.. method:: findtext(path[, default])
2007-08-15 11:28:01 -03:00
Finds the element text for the first toplevel element with given tag.
Same as getroot().findtext(path). *path* is the toplevel element to look
for. *default* is the value to return if the element was not
found. Returns the text content of the first matching element, or the
default value no element was found. Note that if the element has is
found, but has no text content, this method returns an empty string.
2007-08-15 11:28:01 -03:00
.. method:: getiterator([tag])
2007-08-15 11:28:01 -03:00
Creates and returns a tree iterator for the root element. The iterator

.. _elementtree-qname-objects:
QName Objects
-------------
.. class:: QName(text_or_uri[, tag])
QName wrapper. This can be used to wrap a QName attribute value, in order to
get proper namespace handling on output. *text_or_uri* is a string containing
the QName value, in the form {uri}local, or, if the tag argument is given, the
URI part of a QName. If *tag* is given, the first argument is interpreted as an
URI, and this argument is interpreted as a local name. :class:`QName` instances
are opaque.
.. _elementtree-treebuilder-objects:
TreeBuilder Objects
-------------------
.. class:: TreeBuilder([element_factory])
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. The *element_factory* is called to create new
Element instances when given.
.. method:: close()
2007-08-15 11:28:01 -03:00
Flushes the parser buffers, and returns the toplevel document
element. Returns an Element instance.
2007-08-15 11:28:01 -03:00
.. method:: data(data)
2007-08-15 11:28:01 -03:00
Adds text to the current element. *data* is a string. This should be
either an 8-bit string containing ASCII text, or a Unicode string.
2007-08-15 11:28:01 -03:00
.. method:: end(tag)
2007-08-15 11:28:01 -03:00
Closes the current element. *tag* is the element name. Returns the closed
element.
2007-08-15 11:28:01 -03:00
.. method:: start(tag, attrs)
2007-08-15 11:28:01 -03:00
Opens a new element. *tag* is the element name. *attrs* is a dictionary
containing element attributes. Returns the opened element.
2007-08-15 11:28:01 -03:00
.. _elementtree-xmltreebuilder-objects:
XMLTreeBuilder Objects
----------------------
.. class:: XMLTreeBuilder([html,] [target])
Element structure builder for XML source data, based on the expat parser. *html*
are predefined HTML entities. This flag is not supported by the current
implementation. *target* is the target object. If omitted, the builder uses an
instance of the standard TreeBuilder class.
.. method:: close()
2007-08-15 11:28:01 -03:00
Finishes feeding data to the parser. Returns an element structure.
2007-08-15 11:28:01 -03:00
.. method:: doctype(name, pubid, system)
2007-08-15 11:28:01 -03:00
Handles a doctype declaration. *name* is the doctype name. *pubid* is the
public identifier. *system* is the system identifier.
2007-08-15 11:28:01 -03:00
.. method:: feed(data)
2007-08-15 11:28:01 -03:00
Feeds data to the parser. *data* is encoded data.
2007-08-15 11:28:01 -03:00
:meth:`XMLTreeBuilder.feed` calls *target*\'s :meth:`start` method
for each opening tag, its :meth:`end` method for each closing tag,
