What s the simplest way to get the String representation of a XML Document  org w3c dom Document   That is all nodes will be on a single line   As an example  from   lt root gt     lt a gt trge lt  a gt     lt b gt 156 lt  b gt   lt  root gt     this is only a tree representation  in my code it s a org w3c dom Document object  so I can t treat it as a String   to    lt root gt   lt a gt trge lt  a gt   lt b gt 156 lt  b gt   lt  root gt     Thanks

First you need to get rid of all newline characters in all your text nodes  Then you can use an identity transform to output your DOM tree  Look at the javadoc for TransformerFactory newTransformer
