Unless you're using a validating parser and a DTD, you
cannot throw away whitespace.  See section 2.10 of the
XML specification:

    "An XML processor must always pass all characters
    in a document that are not markup through to the
    application"

After all, someone might need those extra newlines. For
example:

    <pre>
       <b>hello</b>
       <i>world</i>
    </pre>

isn't quite the same thing as:

    <pre><b>hello</b><i>world</i></pre>
