DOM method for parsing XML files using the sax Method

This article briefly introduces the dom method for parsing xml by using sax. Because the method of parsing XML files by using a stream mechanism, it reads a row of xml files to parse a row, the code is written in the directory. For more information, see.

The Code is as follows:

Copy code

<? Xml version = "1.0" encoding = "UTF-8"?> <Students> <Student id = "1"> <Name> Yang Zhenyu </name> <Sno> 2008011123 </sno> <Sex> male </sex> <Phone> 18618405551 </phone> </Student> <Student id = "2"> <Name> Zhang Rui </name> <Sno> 2008011122 </sno> <Sex> male </sex> <Phone> 15120058124 </phone> </Student> <Student id = "3"> <Name> Chen Ming </name> <Sno> 2008011121 </sno> <Sex> male </sex> <Phone> 15801281851 </phone> </Student> <Student id = "4"> <Name> su Yujie </name> <Sno> 2008011120 </sno> <Sex> male </sex> <Phone> 18618405551 </phone> </Student> <Student id = "5"> <Name> Gaoyang </name> <Sno> 2008011145 </sno> <Sex> female </sex> <Phone> 18618405590 </phone> </Student> </Students>

 
You can use the following method for parsing:
 

The Code is as follows:

Copy code

Public static void parse (File file) throws Exception { DocumentBuilderFactory factory = DocumentBuilderFactory. newInstance (); DocumentBuilder builder = factory. newDocumentBuilder (); Document doc = builder. parse (file ); Element root = doc. getDocumentElement (); NodeList childList = root. getChildNodes (); For (int I = 0; I <childList. getLength (); I ++ ){ Node child = childList. item (I ); If (child instanceof Element ){ Element element = (Element) child; NodeList childInfo = element. getChildNodes (); For (int j = 0; j <childInfo. getLength (); j ++ ){ Node node = childInfo. item (j ); If (node instanceof Element ){ Element e = (Element) node; Log. v ("tag", "" + e. getTagName ()); Text textNode = (Text) e. getFirstChild (); String text = textNode. getData (). trim (); If (e. getTagName (). equals ("name ")) Log. v ("tag", "" + text ); Else if (e. getTagName (). equals ("sno ")) Log. v ("tag", "" + text ); Else if (e. getTagName (). equals ("sex ")) Log. v ("tag", "" + text ); Else if (e. getTagName (). equals ("phone ")) Log. v ("tag", "" + text ); } }   } } }
