Removing node/element from DOM

[Alien]

I came across this problem where I cant remove element from the document.

Here is my code.

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
 
DocumentBuilder builder = dbf.newDocumentBuilder();
 
Document document = builder.newDocument();
 
document = builder.parse(new InputSource(new StringReader(string)));
 
 

Basically I am reading XML file of another website and putting it in a string and parsing it. Now to implement a search functionality, I need to get rid of an element.

I tried it the following way as suggest by a website while googling,

NodeList nodelist = document.getElementsByTagName("name");
Element e1 = (Element)nodeList.item(1);
e1.getParentNode().removeChild(e1);
 

It removes stuff from the NodeList when I do a out.println() before and after this code to verify, but document remains intact when I print it out (using xsl to format it and Transformer). But thats what I expected anyway.

I simply dont know how to remove an element from the actual DOM document. Any ideas anyone?

Cheers for looking at it.
