Title: IshtarType: ComedyFormat: VHSRating: PGStars: 2Description: Viewable boredomFor a complete detail on SAX API documentation, please refer to standard Python SAX APIs.Parsing XML with DOM APIs: The Document Object Model or "DOM," is a cross-language API from the World Wide Web Consortium (W3C) foraccessing and modifying XML documents.The DOM is extremely useful for random-access applications. SAX only allows you a view of one bit of thedocument at a time. If you are looking at one SAX element, you have no access to another.Here is the easiest way to quickly load an XML document and to create a minidom object using the xml.dommodule. The minidom object provides a simple parser method that will quickly create a DOM tree from the XMLfile.The sample phrase calls the parse( file [,parser] ) function of the minidom object to parse the XML file designatedby file into a DOM tree object.#!/usr/bin/pythonfrom xml.dom.minidom import parseimport xml.dom.minidom# Open XML document using minidom parserDOMTree = xml.dom.minidom.parse("movies.xml")collection = DOMTree.documentElementif collection.hasAttribute("shelf"):print "Root element : %s" % collection.getAttribute("shelf")# Get all the movies in the collectionmovies = collection.getElementsByTagName("movie")# Print detail of each movie.for movie in movies:print "*****Movie*****"if movie.hasAttribute("title"):print "Title: %s" % movie.getAttribute("title")type = movie.getElementsByTagName('type')[0]print "Type: %s" % type.childNodes[0].dataformat = movie.getElementsByTagName('format')[0]print "Format: %s" % format.childNodes[0].datarating = movie.getElementsByTagName('rating')[0]print "Rating: %s" % rating.childNodes[0].datadescription = movie.getElementsByTagName('description')[0]print "Description: %s" % description.childNodes[0].dataThis would produce the following result:Root element : New Arrivals*****Movie*****Title: Enemy BehindType: War, ThrillerTUTORIALS POINT Simply Easy Learning
