Re: [Htmlparser-user] How can I improve the speed of extracting the information of a html page through HtmlParser.

[Ian M. <ian...@gm...>]

You could have a helper thread which pulls in files from the disk and
provides them to a second thread which does the HTML processing.

This doesn't really seem like an HTML parser issue, unless there is a
bug with HTML Parser that makes it slow pulling in files from the
disk. You could check this by instead reading the file into a String
first and then creating a parser with that String using
Parser.setInputHTML and then Parser.parse(null) - if there's a
noticeable difference in speed doing it this way, it might be worth
looking into the code of the HTML Parser constructor you are using to
see if there are any inefficiencies in it.
