Cubist  is correct.  Any well-formed page will have balanced tags and only
use the < and > chars to mean tag markers.

If the data is critical to you, then beware of exceptions.  There could be
incomplete downloads and less-than-professional html code that is received
by Rev which could contain confusing "< >" instances.  This is a good reason
to do the 'one-tag-per-one-line' approach and view the result to locate any
weirdness before trusting the data.

The correct way to tell html to show the viewer a character is
a    <  is > 
a    > is  <   
a    &  is  &
and many more for various language characters and high ascii

You could test for an incomplete download by finding the last tag of
"</html>".  If it is missing, you should retry.
