Hi

I have the following perl code that extracts   Alexander_Hamilton_Jr. from the following string

http://en.wiedia.org/wiki/Alexander_Hamilton_Jr./Sr._High_School

it is supposed to give Alexander_Hamilton_Jr./Sr._High_School


 ($part0,$id,$wikiid,$fiwd,$part4)=m{(.*?(?:(www\.idb\.com)|(en\.wiedia\.org)|(frase\.com))/[^/]*)/([^/]*)};

what do i need to do

Try this:

my $str = "http://en.wiedia.org/wiki/Alexander_Hamilton_Jr./Sr._High_School";

my ($match) = $str =~ m{wiki/(.+)};

print $match;

hi

thanks for the reply
can you help by changing the existing code, as you can see it matches other domains as well

thanks

Ok, changed it like this and it works:

$_ = $str;

my ($id,$wikiid,$fiwd) = m{(.*?(www\.idb\.com|en\.wiedia\.org|frase\.com)(?:/wiki)/[^/]*)/([^/]*)};

print "$wikiid/$fiwd";

Open in new window


Your expression missed the wiki part altogether.  Also you don't need to put your URLs in brackets.

The simplest change necessary would be to just change the very last portion of the regex:
 ($part0,$id,$wikiid,$fiwd,$part4)=m{(.*?(?:(www\.idb\.com)|(en\.wiedia\.org)|(frase\.com))/[^/]*)/(.*)};

Open in new window

Now it will match anything after the "wiki" (or similar) portion of the URL.  Some examples:
http://en.wiedia.org/wiki/Alexander_Hamilton_Jr./Sr._High_School -> Alexander_Hamilton_Jr./Sr._High_School
http://en.wiedia.org/whatever/this/is/long/url.html -> this/is/long/url.html
