1. File read_xml_1.py: Get any label signature

#coding =utf-8import xml.dom.minidom Dom =xml.dom.minidom.parse (' e:\\selenium_relatived\\learning\\info.xml ') root = Dom.documentelementprint (root.nodename) tagname = root.getelementsbytagname (' browser ') print (tagname[0].tagname) tagname1 = root.getelementsbytagname (' login ') print (tagname1[1].tagname) tagname2 = Root.getelementsbytagname (' Province ') print (tagname2[2].tagname)

getElementsByTagName gets the label by its tag name, and the object it obtains is stored as an array

2. File read_xml_2.py: Get the properties of a tag

#coding =utf-8import xml.dom.minidom Dom =xml.dom.minidom.parse (' e:\\selenium_relatived\\learning\\info.xml ') root = Dom.documentelementprint (root.nodename) logins = root.getelementsbytagname (' login ') username=logins[0]. GetAttribute (' username ') print (username) username1=logins[1].getattribute (' username ') print (username1)

3. Get the data between label pairs

#coding =utf-8import xml.dom.minidom Dom =xml.dom.minidom.parse (' e:\\selenium_relatived\\learning\\info.xml ') root = Dom.documentelementprint (root.nodename) province = Dom.getelementsbytagname (' province ') Citys = Dom.getelementsbytagname (' City ') P2=province[1].firstchild.dataprint (p2) c1 = Citys[0].firstchild.dataprint (C1)
