Actually, there is a currently undocumented trick to do this. If you use
external_parser: text/html->text/html-internal /usr/local/bin/foobar.pl
it will actually run the foobar.pl script to preprocess the HTML before
parsing it with the internal HTML parser. The drawback is the performance
penalty, because all HTML files will have to go through this Perl script,
with Perl being restarted for each one. If this is a big problem, the
only other option is to patch the htdig/HTML.cc parser code, to treat the
<h3>...</h3> tags the way it currently treats the <title>...</title> tags.
