If you already know how to read and write the XML to and from a DOM, then what is your problem?
ya but there is ip address i cant display that NodeList childNodeList15 = element.getElementsByTagName("ue_ip_address"); for (i = 0; i < childNodeList15.getLength(); i++) { Node childNode15 = childNodeList15.item(i); if (childNode15.getNodeType() == Node.ELEMENT_NODE) { libElement = (Element) childNode15; ip1 = Integer.parseInt(libElement.getFirstChild().getNodeValue()); NamedNodeMap var2 = childNode15.getAttributes(); Node var3 = var2.getNamedItem("default"); cell18 = var3.getTextContent(); Node desc = var2.getNamedItem("Description"); cdes18 = desc.getTextContent(); } } this how im reading xml element and storing ip address in ip1 if i run im gating error in this line ip1 = Integer.parseInt(libElement.getFirstChild().getNodeValue());

Well, I'm afraid we cannot guess what that error could be. I suggest you step through the code with your debugger and look at the error that is produced, and the values of all variables that are being used in that statement.
thank u Richard MacCutchan 1st error is ip1 variable i declared as double 2nd i used Integer.parseInt i think it wont match so please don't mistake me i need two solutions 1.on which data type my variable have to declare 2.how to convert string to declared variable dataype

Assuming that
ip1is part of an IP address, I cannot see any reason why you would declare it as adouble. You could make things simpler by using theInetAddressclass[^] to do the conversions. -

I have given you the link to the documentation, so you should go there, read it, and try some of the methods for yourself. Learning by doing is much more useful than having someone else do it for you.
thank u Richard MacCutchan!!! what ever u sent right now im reading if i got any doubts i ask you thank u

I'm curious. Can you provide a snippet of the XML file you are trying to read? -chronodekar
