Python Basic-xml parsing

Python provides two ways to parse XML

SAX Simple API FOR XML

Suitable for parsing large files, because parsing content is not saved in content, but is invoked when parsing to related content

DOM Document Object Model

Reads the entire document into memory to form a tree structure

Sax Parsing Methods

    ImportXml.saxclassMyxmlhandler (xml.sax.ContentHandler):def __init__(self): name=""            defstartelement (self,tag,attributes):Print "startelement Tag:"+TagPrintattributesdefendElement (self,tag):Print "endElement Tag:"+Tagdefcharacters (self,content):#print "charaters:" +self. Currenntdata            PrintcontentPrint ""Parser=Xml.sax.make_parser ()#Turn off Namepsaces    #? Parser.setfeature (xml.sax.handler.feature_namespaces, 0)Handler=Myxmlhandler () Parser.setcontenthandler (Handler) parser.parse ("Example-req.xml")

How DOM is parsed

Much more concise.

 from Import Parse Import  = Xml.dom.minidom.parse ("example-req.xml"=  Domtree.documentelementactivitycode=collection.getelementsbytagname ("activitycode " )print activitycode[0].childnodes[0].data
