The most obvious bug I see is in this section of your code: 
my $i=1;
for my $href(@href) {my $url4= "http://www.ebi.ac.uk$href[$i];
$content=get($url4);
$i=$i+1;
}
}

Style-wise, I would write it like: 
for my $param ( @href ){
   my $content = get ( "http://www.ebi.ac.uk$param" );
   process_content ($content); # << This is missing from your code !!!
}

....
sub process_content{
  my $content = shift;
  .. Build HTML tree etc ...

}

In your code, $content is being overwritten for each href.
