It looks like that's what you asked for. I'm not sure what the problem is. -- <http://www.dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply]

The problem is that i need every IP only once. (Sorry if i didn't say that before). So i only need to get the IPAddress and not also the NEIGHBOURIPAddress, bacause then i have everything only once.	[reply]

If you ever need to get unique values in Perl then you should think about using a hash. `use XML::XPath; my $xp = XML::XPath->new(filename => '/path/to/file'); my %seen; foreach ('IP-ADDRESS', 'IP-NEIGHBOUR') { foreach my $ip ($xp->findnodes("//$_")) { my $addr = $ip->findvalue('.'); print "$addr\n" unless $seen{$addr}++; } }` [download] -- <http://www.dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply] [d/l]

ok here is another idea I had: # use XML::Dumper; open (XMLINPUT, "e:/topo.xml") or (print "Die XML Datei konnte nicht geöffnet werden!!\n". "Bitte Pfad und Dateiname mit Slashs angeben!!". "\nz.B. c:/data1.xml\n" and open (MACERROR, ">XMLError.err") and print MACERROR "Die XML Datei konnte nicht geöffnet werden!!\n +". "Bitte Pfad und Dateiname mit Slashs angeben!!". "\nz.B. c:/data1.xml\n" and close MACERROR and exit); # Zeiger erzeugen $zeiger_xml = new XML::Dumper->xml2pl(join("",<XMLINPUT>)); $zeiger_data = \@{$zeiger_xml->{'Data'}}; close XMLINPUT; open (CACHENEU, ">ips2.txt"); close CACHENEU; foreach $z_device (@{$zeiger_xml->{'Device'}}) { #if ( $z_device->{'SystemDescription'} =~ m/Version 12.0 +$5$/ #and $z_device->{'SystemDescription'} =~ m/C2900/ #and $z_device->{'SystemDescription'} !~ m/WS/) #{ open (CACHENEU, ">>ips2.txt"); foreach $z_add (@{$z_device->{'DeviceName'}}) { %PortHash = ( $z_device->{'DeviceName'} => $z_ip->{'IPAddr +ess'} ); printf CACHENEU ("%s\t\t%s\n",%PortHash); } close CACHENEU; #} } print "\nfertig Portliste erstellen!!\n" ; [download] and this is the File I have to read from: <?xml version="1.0" encoding="UTF-8" ?> - <CMData> <CMServer>S03</CMServer> <CreatedAt>Tue Aug 24 09:09:41 GMT+02:00 2004</CreatedAt> <SchemaVersion>1.0</SchemaVersion> <Heading>Topology Data</Heading> - <Layer2Details> - <Device> <DeviceName>LWL-H91-CW-4-5-4</DeviceName> <IPAddress>148.192.59.254</IPAddress> <DeviceState>Reachable</DeviceState> <DeviceType>C2950G-24</DeviceType> - <Neighbors> - <Neighbor> <NeighborIPAddress>148.192.22.22</NeighborIPAddress> <NeighborDeviceType>C6506</NeighborDeviceType> <Link>Point to Point link</Link> <LocalPort>Gi0/2</LocalPort> <RemotePort>3/3</RemotePort> </Neighbor> [download] Any idea on where I am mistaking??
