An example of using Sax to parse XML in Android

The config. xml file is as follows:

<Config> <br/> <string-array name = "system_app_ti60"> <br/> <item> browser.apk </item> <br/> <item> phone.apk </item> <br/> <item> contact.apk </item> <br/> <item> settings.apk </item> <br/> <item> gmail.apk </item> <br/> </string-array> <br/> </config>

 

The following are the main classes used:

Import org. xml. Sax. attributes;
Import org. xml. Sax. saxexception;
Import org. xml. Sax. helpers. defaulthandler;
Import javax. xml. parsers. saxparserfactory;
Import javax. xml. parsers. saxparser;
Import javax. xml. parsers. parserconfigurationexception;

 

Xmlparser class: used to process read data, such as tags and text.

Private class xmlparser extends defaulthandler <br/>{< br/> private arraylist <string> array = new arraylist <string> (); <br/> string mname = NULL; <br/> private Boolean mfound = false; </P> <p> Public arraylist <string> getarraystring () {<br/> return array; <br/>}< br/> // callback when the start tag information is read <br/> @ override <br/> Public void startelement (string Uri, string localname, string QNAME, attributes) THR Ows saxexception {<br/> If (localname. equals ("string-array") {<br/> mname = attributes. getvalue (0); <br/> If (mname. equals ("system_app_ti60") {<br/> mfound = true; <br/>}</P> <p >}< br/> // callback when reading text information <br/> @ override <br/> public void characters (char ch [], int start, int length) throws saxexception {<br/> If (mfound) {<br/> string value = new string (CH, start, length ); <br/> If (! Value. endswith ("APK") <br/> return; <br/> array. add (value ); <br/>}< br/> // callback when the end tag information is read <br/> @ override <br/> Public void endelement (string Uri, string localname, string QNAME) throws saxexception {<br/> If (localname. equals ("string-array") {<br/> If (mfound) {<br/> mfound = false; <br/>}</P> <p >}< br/>}

 

Call test:

Try {<br/> saxparserfactory factory = saxparserfactory. newinstance (); <br/> saxparser parser = factory. newsaxparser (); <br/> xmlparser handler = new xmlparser (); <br/> parser. parse (new file ("/system_extend/system_extend_config.xml"), Handler); <br/> applist = handler. getarraystring (); </P> <p >}< br/> catch (saxexception e) {<br/> log. I ("hxd", "saxexception"); <br/> return; <br/>}< br/> catch (parserconfigurationexception e) {<br/> log. I ("hxd", "parserconfigurationexception"); <br/> return; <br/>}< br/> catch (ioexception e) {<br/> log. I ("hxd", "ioexception"); <br/> return; <br/>}< br/>}
