synopsis: Minimal Document Object Model (DOM) implementation.

Source code: Lib/xml/dom/minidom.py

!xml.dom.minidom is a minimal implementation of the Document Object Model interface, with an API similar to that in other languages. It is intended to be simpler than the full DOM and also significantly smaller. Users who are not already proficient with the DOM should consider using the xml.etree.ElementTree module for their XML processing instead.

If you need to parse untrusted or unauthenticated data, see xml-security.

DOM applications typically start by parsing some XML into a DOM. With !xml.dom.minidom, this is done through the parse functions

from xml.dom.minidom import parse, parseString

dom1 = parse('c:\\temp\\mydata.xml') # parse an XML file by name

datasource = open('c:\\temp\\mydata.xml') dom2 = parse(datasource) # parse an open file

dom3 = parseString('Some data some more data')

The parse function can take either a filename or an open file object.

Return a Document from the given input. filename_or_file may be either a file name, or a file-like object. parser, if given, must be a SAX2 parser object. This function will change the document handler of the parser and activate namespace support; other parser configuration (like setting an entity resolver) must have been done in advance.

If you have XML in a string, you can use the parseString function instead

Return a Document that represents the string. This method creates an io.StringIO object for the string and passes that on to parse.

Both functions return a Document object representing the content of the document.

What the parse and parseString functions do is connect an XML parser with a "DOM builder" that can accept parse events from any SAX parser and convert them into a DOM tree. The names of the functions are perhaps misleading, but are easy to grasp when learning the interfaces. The parsing of the document will be completed before these functions return; it's simply that these functions do not provide a parser implementation themselves.

You can also create a Document by calling a method on a "DOM Implementation" object. You can get this object either by calling the getDOMImplementation function in the xml.dom package or the !xml.dom.minidom module. Once you have a Document, you can add child nodes to it to populate the DOM

from xml.dom.minidom import getDOMImplementation …
