Dear all,

Sorry, this is still a mystery to me. Why do I have to use xml or whatever, but not just a simple script like one below:

It was discussed a few times, but why it should be so complicated?

#!/usr/bin/perl

use LWP::UserAgent;

my $ua = new LWP::UserAgent;
my $response = $ua->get('http://www.example.com/');


# my url has to be like:
# http://www.ncbi.nlm.nih.gov/protein/WP_005451061.1?report=fasta&log$=seqview&format=text

unless ($response->is_success) {
        die $response->status_line;
}

my $content = $response->decoded_content();
if (utf8::is_utf8($content)) {
        binmode STDOUT,':utf8';
} else {
        binmode STDOUT,':raw';
}

print $content;

I have a lot of NCBI ids, like WP_005451061.1, many thousands.

I will have to find their respective UniProt ids, won't !?

http://www.ncbi.nlm.nih.gov/protein/WP_005451061.1?report=fasta&log$=seqview&format=text

Is it correct that there is no way to use the fasta-sequence encoded by the url above and I can reach it only manually? Thank you very much for your advice!

Sincerely yours,
Natalia
