Yes you can. Use the setTextContent() on the specific node you need.

that is to set the String..bt how to replace that string with other string..
can u tel me thru certain code...

[Eranga]

Here is a simple code segment. Replace with appropriate values relevant to your code.

// Use the xpath as follows
XPath myXPath = XPathFactory.newInstance().newXPath();
XPathExpression myExpression = myXPath.compile("//title");

// Get the node
Node myNode = (Node)myExpresion.evaluate(document, XPathConstants.NODE);
 
// Update the text with your value
myNode.setTextContent("hisssss");

Haven't test it. There can be spelling error. It should work, have a try.

Read the whole file get into a buffered reader and write back to a new file. Do it as simple file read/write process.
