Home: Perl Programming Help: Intermediate: Text Extraction

AlanB Novice Nov 13, 2005, 4:20 AM Post #1 of 2 (555 views) Text Extraction Can't Post I have written a small Perl script that uses LWP::Simple to extract the source code of a web page into variable $content. The web page contains information on the current exchange rate of the Euro against various currencies and I need to be able to extract the relevant value for British pounds. About halfway down the page in a 3-column table you can find: GBP Pound sterling 0.671 Can anyone advise what code / module I now need to use to grab this piece of information. The actual code I have used is as follows: #!/usr/bin/perl use CGI; use CGI::Carp qw(fatalsToBrowser); use LWP::Simple; my $content=get("http://www.ecb.int/stats/exchange/eurofxref/html/index.en.html"); print "Content-type: text/html\n\n"; print $content; $content prints the whole page - I need to locate Pound sterling and extract the value (0.671 or whatever the current exchange rate is) so I can use that against my web site page calculations Thanks Alan

I usually usually use HTML::TreeBuilder, but in this case HTML::TableExtract might be more appropriate. -- Dave Cross, Perl Hacker, Trainer and Writer http://www.dave.org.uk/ Get more help at Perl Monks
