Java background parsing string form of Xml__java

Flex through Request , the foreground is packaged into Xml To the background, now roughly speaking, in the background javax is how to resolve String form of Xml , convert it to Bean , the following method is the way I save Personal address information when I do contact management, and the red flag is to get the value of the corresponding node attribute in a node.

Public void saveaddr (String address) {

System.out.println ("In CMD, save address Information");

Documentbuilderfactory factory = Documentbuilderfactory.newinstance ();

Documentbuilder Builder;

Try {

Builder = Factory.newdocumentbuilder ();

StringReader sr = New StringReader (address);

InputSource is = new inputsource (SR);

Document doc = Builder.parse (IS);

list<contactaddr> list = new arraylist<contactaddr> ();

NodeList nodelist=doc.getelementsbytagname ("address");

for (int i=0;i<nodelist.getlength (); i++) {

Contactaddr contactaddr=New contactaddr ();

if ("Mailbox". Equals

(Nodelist.item (i). GetAttributes (). getNamedItem ("mode"). Getnodevalue ())

{

Contactaddr.setdeliverymode ("1");

}Else{

Contactaddr.setdeliverymode ("0");

}

Contactaddr.setdeliveryaddr

(Nodelist.item (i). GetAttributes (). getNamedItem ("addr"). Getnodevalue ());

List.add (CONTACTADDR);

}

SERVICE.UPDATECONTACTADDR (list);
