Let's look at the IBM problem.

IBM was one of the business I tested, and it worked. Actually one of the business came back under IBM was IBM Japan, and I got some wide charatcters.

I cannot cut and paste my testing result now, as I am behind firewall, but I definitely will update this post tonight. (I can enhance the code to work with firewall, but ...)

My guess is that, when you only got one business back in the SOAP reply, XML::Simple does not parse it into an array ref, as it does when multiple business were sent back, and I missed that. So I probably should do a ref() first.

However you should get the same SOAP reply as I did, when we both enquery IBM. This puzzles me a lot.

Here is the updated code, but the enhancement is untested, which I do tonight back home.

use Socket;
use IO::Select;
use XML::Simple;
use Data::Dumper;
use strict;
use warnings;

while (1) {
    print "Business: ";
    my $business = <>;
    chomp($business);
    if ($business) {
        my $businesses = find($business);
        display($businesses);
    } else {
        last;
    }
}

sub display {
    my $businesses = shift;
    foreach my $key (keys(%$businesses)) {
        print "-$key\n";
        print "---$businesses->{$key}\n" if(defined($businesses->{$key
+}));
    }
    print "=========================================\n";
}

sub find {
    my $name = shift;
    socket(UDDI, PF_INET, SOCK_STREAM, getprotobyname('tcp')) || die "
+socket: $!";
    connect(UDDI, sockaddr_in(80, inet_aton("www-3.ibm.com"))) || die 
+"connect: $!";
    my $envelope =     
        "<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.or
+g/soap/envelope/\">" .
            "<SOAP-ENV:Body>" . 
                "<find_business generic=\"2.0\" maxRows=\"100\" xmlns=
+\"urn:uddi-org:api_v2\">" .
                    "<name>" . $name . "</name>" .
                "</find_business>" .
            "</SOAP-ENV:Body>" .
        "</SOAP-ENV:Envelope>";

    my $msg = 
    "POST /services/uddi/inquiryapi HTTP/1.1\r\n" .
    "Content-Type: text/xml; charset=\"utf-8\"\r\n" .
    "Content-Length: " . length($envelope) . "\r\n" .
    "SOAPAction: \"\"\r\n" .
    "Cache-Control: no-cache\r\n" .

    "Connection: keep-alive\r\n" .
    "\r\n" .
    $envelope;
    syswrite(UDDI, $msg);
    
    my $res = "";
    my $sel = new IO::Select(*UDDI);
    while ($sel->can_read) {
        my $chunk;
        sysread(UDDI, $chunk, 100000);
        if (!length($chunk)) {
            last;
        } else {
            $res .= $chunk;
        }
    }
    close(UDDI);
        
    $res =~ m/.*?\r\n\r\n(.*)/;
    $res = $1;
    my $hash = XMLin($res);

    my $result = {};
    if (ref($hash->{"SOAP:Body"}->{"businessList"}->{"businessInfos"}-
+>{"businessInfo"}) eq "ARRAY") {
        foreach my $business (@{$hash->{"SOAP:Body"}->{"businessList"}
+->{"businessInfos"}->{"businessInfo"}}) {
            $result->{$business->{"name"}->{"content"}} = $business->{
+"description"}->{"content"};
        }
    } else {
        #I will add later, as I cannot test now, and I don't want to p
+ost untested code in this case
    }
    return $result;
}
