Remove all attributes from an element using Java

Question

I need to remove all attributes from a particular element in a Document.

How I have the xml :

    <Book>
     <Chapter TotalNoOfWords="2000" NoOfPages="5">
       <Line LineNo="1" NumberOfWords="50"/>
     </Chapter>
    </Book>

How I need it to be :

    <Book>
     <Chapter>
      <Line LineNo="1" NumberOfWords="50"/>
     </Chapter>
    </Book>

I am aware of the removeAttribute() method. But this method will only remove the attribute for which the name has been passed as an argument to this method. I am looking for something that will remove all attributes in the element. Any help on this.

Answer 1

Assuming you already have the specified Node element, loop through all the elements and remove them...

while (node.getAttributes().getLength() > 0) {
    Node att = node.getAttributes().item(0);
    node.getAttributes().removeNamedItem(att.getNodeName());
}

For example...
