If anyone has a use for a *streaming* permissive HTML parser (i.e., one
that calls your specific bits of code while it's parsing, rather than it
constructing some kind of representation of the entire page for your
code to process afterwards), I'd be interested in what specifically
you'd like it to do.
(For example, in a simplifying/security Web proxy, in which you want to
reduce memory requirements on the proxy host, and perhaps also response
latency, by transforming as you go. Or in a Web scraper for large query
results, in which, say, you want to be sending a large amount of
extracted data to as rows to a different database without buffering up a
huge page and/or the rows. Or for scraping a small part of a large page
without allocating a parsed representation of the entire page. Or maybe
you'd like the performance properties of streaming, and the convenience
of a pattern-based scraper or transformation language atop that. )
