If not given, the standard XMLParser parser is used. Returns an Element instance. Parses an XML document from a sequence of string fragments. Appends whitespace to the subtree to indent the tree visually. This can be used to generate pretty-printed XML output. For indenting partial subtrees inside of an already indented tree, pass the initial indentation level as level.
Check if an object appears to be a valid element object. Return True if this is an element object. If events is omitted, only "end" events are reported. Returns an iterator providing event, elem pairs. Note that while iterparse builds the tree incrementally, it issues blocking reads on source or the file it names.
The same applies to the element children; they may or may not be present. Parses an XML section into an element tree. Returns an ElementTree instance. PI element factory. This factory function creates a special element that will be serialized as an XML processing instruction. Returns an element instance, representing a processing instruction. Note that XMLParser skips over processing instructions in the input instead of creating comment objects for them.
An ElementTree will only contain processing instruction nodes if they have been inserted into to the tree using one of the Element methods. Registers a namespace prefix. The registry is global, and any existing mapping for either the given prefix or the namespace URI will be removed.
Tags and attributes in this namespace will be serialized with the given prefix, if at all possible. 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 bytestrings or Unicode strings. Returns an element instance. Generates a string representation of an XML element, including all subelements. Returns an optionally encoded string containing the XML data.
New in version 3. Returns a list of optionally encoded strings containing the XML data. It does not guarantee any specific sequence, except that b"". Parses an XML section from a string constant, and also returns a dictionary which maps from element id:s to elements.
Returns a tuple containing an Element instance and a dictionary. This module provides limited support for XInclude directives , via the xml. ElementInclude helper module. This module can be used to insert subtrees and text strings into element trees, based on information in the tree. By default, the href attribute is treated as a file name. You can use custom loaders to override this behaviour. Also note that the standard helper does not support XPointer syntax.
To process this file, load it as usual, and pass the root element to the xml. ElementTree module:. The result might look something like this:. The href attribute is required. Default loader. This default loader reads an included resource from disk. If not given, encoding is utf Returns the expanded resource. If the parse mode is "xml" , this is an ElementTree instance.
If the loader fails, it can return None or raise an exception. This function expands XInclude directives. Limited to reduce the risk of malicious content explosion.
Pass a negative value to disable the limitation. Element class. This class defines the Element interface, and provides a reference implementation of this interface. A string identifying what kind of data this element represents the element type, in other words. These attributes can be used to hold additional data associated with the element. Their values are usually strings but may be any application-specific object.
For the XML data. To collect the inner text of an element, see itertext , for example "". 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. Resets an element. This function removes all subelements, clears all attributes, and sets the text and tail attributes to None. Returns the element attributes as a sequence of name, value pairs. The attributes are returned in an arbitrary order. Raises TypeError if subelement is not an Element. Appends subelements from a sequence object with zero or more elements.
Raises TypeError if a subelement is not an Element. Finds the first subelement matching match. Returns an element instance or None. Pass '' as prefix to move all unprefixed tag names in the expression into the given namespace. Finds all matching subelements, by tag name or path. Returns a list containing all matching elements in document order.
Finds text for the first subelement matching match. 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. Inserts subelement at the given position in this element. Creates a tree iterator with the current element as the root. The iterator iterates over this element and all elements below it, in document depth first order. If the tree structure is modified during iteration, the result is undefined.
Returns an iterable yielding all matching elements in document order. Viewed 2k times. Improve this question. Phil Sturgeon.
