[J radolf]

http://www.developerfusion.com/code/2064/a-simple-way-to-read-an-xml-file-in-java/

i want to know how do i read the xml if it is of the below format.

 
<?xml version="1.0"?>
<KONAM>
   <PROPERTIES>
       <DESPROXY
      
      CLIENT_DBNAME         = "CHANGEME"
      CLIENT_USERNAME    = "CHANGEME"
      CLIENT_PASSWORD    = "CHANGEME"
      SERVER_DBNAME        ="CHANGEDBNAME"
      SERVER_USERNAME   ="SERVERNAME"
      SERVER_PASSWORD   ="SERVERPASSWORD" />
</PROPERTIES>
</KONAM>

can anyone help me up to come up with a new idea?

Too difficult a question for us beginners. Moving.

By "this kind", do you mean the attributes? If so, check out the DOM methods Node.getAttributes and Element.getAttribute.

[J radolf]

like there are several attributes inside the same DESPROXY tag.

so how would i do that?

because in my case there are several key-value pairs.

        	 if(firstValueNode.getNodeType()==Node.ELEMENT_NODE) {
        		 Element firstValueElement=(Element)firstValueNode;
        		 NodeList firstValueList=firstValueElement.getElementsByTagName("REQUIRED");
        		 Element firstNameElement=(Element)firstValueList.item(0);
        	//	 NodeList textFNList=firstNameElement.getChildNodes();
        	//	 System.out.println("first value" +((Node)textFNList.item(0)).getNodeValue().trim());
        		 String textFNList=firstNameElement.getNodeValue(); /*****DOUBT LINE*******/
        		 System.out.println("Value is " +textFNList); /******DOUBT LINE**********/
        		 
        	 }
        	 
         }
         
		}catch(Exception e ){
			e.printStackTrace();
		}

	}

}
   

my xml is as follows..

    <DESPROXY
      REQUIRED                  = "N"
      FREQUENCY                 = "100"
      ALERTNAME                 = "DESProxyServer_PICKMEUP"
      CLIENT_USERNAME           = "CHANGEME"
      CLIENT_PASSWORD           = "CHANGEME"
      CLIENT_DATABASE           = "CHANGEME"/>  

i do not know and understand how to read the values in DESPROXY element
that is "N" "100" and other values .
please anyone can help me?

am getting a nullpointerException because it is not reading the values?

what should be my next step?

Reading the responses from Ulf and David would probably be a good first step.

By "this kind", do you mean the attributes? If so, check out the DOM methods Node.getAttributes and Element.getAttribute.

where do i put these methods in my code? after DESPROXY tag value returns?

Well, they are methods of the Node and Element classes, so you will need an instance of one of these classes in order to call them.
Find out where in your code you have these instances and then experiment with calls to these methods and see what data they return.

Thanks guys.

Finally i solved it.

Thanks Everyone.
