This, in some ways, follow on from the discussions on extracting the raw text from an HTML source (see the How to get HTML::Parser to return a line of parsed text thread.

What I would like to do is to extract the first n words of printable data from a string of HTML text.

Using the code:

# Create a new, empty, scalar my $text = ""; # Define what the parser does my $p = HTML::Parser->new( text_h => [ sub {$text .= shift}, 'dtext' ] ); # .. and parse! $p->parse($full_text);

Based on this, it is quite easy to then get the first n words:

# now hack off the first lump of words @list_of_words = split /[ \t\r\f]+/, $text, $n;

However, how do I then correlate the words from @list_of_words to the start of the HTML text in $full_text?
(The plan being that I can do the "blah blah blah (more...)" thing...
