this gives me a DTD as output.
My problem is I want to parse this output!
But how can ich give it to the second code that this parses the result
of (sub_daten_einlesen)
I hope someone understands my question ;-)

#!/usr/bin/perl -w
use LWP::Simple;

sub daten_einlesen
{
print "geben Sie ein gtpprotein ein\n";
my $eingabe =<STDIN>;

my
$url='http://eutils.ncbi.nlm.nih.gov/entrez/eutils/egquery.fcgi?term=';
# print $url;
# print"\n";
$newurl= $url.$eingabe;
# print $newurl;
return $newurl;

}

$url1 =daten_einlesen();
$doc = get $url1;
print $doc;

#!/xprog/bin/perl

# use module
use XML::Simple;
use Data::Dumper;

# create object
$xml = new XML::Simple;

# read XML file
$data = $xml->XMLin("which path???");

# print output
print Dumper($data);

DTD?
As in the kind of document that describes XML files?
If yes, an XML Parser might be the wrong tool for parsing this kind of file.
Could you give us an example?

If the output you want to parse is stored in $doc, you should be able to pass
it directly to XML::Simple:

my $data = $xml->XMLin($doc);
