Incidentally - I AM using Project Wonder ;o). And that was
delightful, thanks!
BTW, I'm using the parseDOM method on Tidy there, which returns a DOM
Document object. You can also use "parse" which returns nothing so I
imagine it's faster (without actually having any idea).

Pretty neat little cleanup trick ... Incidentally, if you use
Project Wonder, switching to:
ByteArrayInputStream in = response.content().stream();
ERXRefByteArrayOutputStream out = new
ERXRefByteArrayOutputStream();
tidy().parseDOM(in, out);
response.setContent(out.toNSData());
should give you better memory/performance ... the comparison is:
1) response.contentString() (copy if NSData-backed)
2) .getBytes() = copy
3) new ByteArrayInputStream(byte[]) = copy
4) writing to ByteArrayOutputStream = copy
5) byteStream.toByteArray() = copy
6) new NSData(byte[]) = copy
the Wonder variant one is:
1) response.content() (copy if String-backed)
2) writing to ByteArrayOutputStream = copy
there might be one more copy in the Wonder variation (I didn't
spend too much time digging into .content()), but still at least
cut in half on the copies. If you don't use wonder, you can just
steal ERXRefByteArrayOutputStream -- it's basically BAOS, but
modified to give direct access to the byte buffer. BAOS normally
only hands back a copy, which sort of sucks most of the time.
