[one-users] list of ip addresses of network deployed in the frontend

[Miguel Morillo Iruela]

Hello,

I wrote a perl script to extract the information that I need from XML-RPC:
http://opennebula.org/documentation:rel3.8:api#onevmpoolinfo

The sniped code:

my @vmpoolany = &getVMPoolInfo(-1,-1,-1,-1); # Información de maquinas en
estado Any state, except DONE
my @ips = &getVMPoolFilterInfo(@vmpoolany ,"IP"); # Devuelve la información
extraída del XML de getVMPoolInfo, en nuestro caso las IPs


sub getVMPoolInfo {
    my $flag;
    my $start;
    my $end;
    my $filter;
    ($flag,$start,$end,$filter) = @_;

    my @response = $server->call('one.vmpool.info', $one_auth,
$flag,$start,$end,$filter);

    return @response;
}


sub getVMPoolFilterInfo {
    my @vmpoolinfo;
    my $filter;
    my $vmpoolinfoparam;

    ($vmpoolinfoparam,$filter) = @_;

    @vmpoolinfo =  @{$vmpoolinfoparam};


    if($vmpoolinfo[2] != 0){
            $errorcode = $vmpoolinfo[2];
    }
    $XML = $vmpoolinfo[1];

    # Limpiamos XML recibido
    $XML =~ s/\"/\'/g;
    $XML =~ s/<!\[CDATA\[//g;
    $XML =~ s/\]\]>//g;

    #
http://oreilly.com/perl/excerpts/system-admin-with-perl/ten-minute-xpath-utorial.html
    my $xp = XML::XPath->new($XML);

    my $nodeset = $xp->find("//$filter/text()");
    my @infofilter;

    foreach my $node ($nodeset->get_nodelist) {
        push(@infofilter, XML::XPath::XMLParser::as_string($node));
    }

    return @infofilter;

}


Regards
Miguel
