How to serialize recursively the content of one node into a String with Xalan J2

[MAHE Vincent FTRD/DIH/REN]

Is it possible to serialize as a java string the content of one node and all
its descendants ?

For example, if I have the following node :
        <toto class="titi">
                <titi>bla bla</titi>
        </toto>

I want to get the following string : "<toto class="titi">\n<titi>bla
bla</titi>\n</toto>"

Thanks.
