Actually, from the example you posted, you want to add a whole <code> element, not just a <code> tag.
But anyway, just parsing a document doesn't, and can't, modify the document in any way. You'll need to first change your logic to echo the input to a new document. Then, change your logic again so that after writing out the start tag for the <book> element, you write out the <code> element as well.
