I have been working with xml, and svn *codebase* for 2 projects now, but never really used url's for picking up xml files.

Now I found this script, that doesn't work:

[perl]#!/usr/bin/perl -w
use strict;
use CGI;
use XML::Simple;

my $xml = new XML::Simple;

my $xmlData = $xml->XMLin("someurl");

print "$xmlData->{code} name is $xmlData->{name} countryname is $xmlData->{CountryName} section\n";[/perl]

So basically I want to retreive a xml document from a url, and then write it away later, so right now all I need is to have a variable, which can show me the elements of the xml file.

hope you can help me.

whoops, now I made another script, which does kind of... the right thing, just doesnt show me want I want to see:

[perl]#!/usr/bin/perl -w
use strict;
use CGI;
use LWP::Simple;
use XML::TreeBuilder;
my $url = "http://maps.google.com/maps/geo?q=";
my $google_code = "ABQIAAAAdyFdLejQuxLR-DS7Xwf_ghTToTrERikbexcU9K8fttM4HbfNkBTdvrL8Yjz6FdJPefFm8jXo852aDA";

for(my $pc=11114; $pc < 11115; $pc++){

for(my $pl=80; $pl < 82; $pl++){
for(my $pl1=80; $pl1 < 82; $pl1++){

print retreiveXml(dirtyNumberTrick($pc) . chr($pl) . chr($pl1), $url, $google_code) . "\n";


sub dirtyNumberTrick{
my($value) = @_;
return substr($value,1);

sub retreiveXml{
my($pc, $url, $google_code) = @_;
my $link = "$url$pc,NL&output=xml&key=$google_code";
my $xmlPage = get $link;

sub extractDataXml{
my ($dataToUse) = @_;
my $tree = XML::TreeBuilder->new();
print $dataToUse;
foreach my $postalCodeData ($tree->find_by_tag_name('Response')){
my $blie = $postalCodeData->find_by_tag_name('name');
print $blie;




This is supposed to show the <name>1032,ER</name>

error comes up,

not well-formed (invalid token) at line 9, column 25, byte 243 at C:/Perl/lib/XML/Parser.pm line 187

It looks like the module is complaining about the specific XML you're trying to parse? Since you can't control the feed there's nothing you can do unless there's a flag you can use to change the parser's perspective on what constitutes valid XML.

I generally use regular expressions to parse XML. A one line regular expression is usually all you need to parse a given feed, which is vastly more efficient and gets around picky parser issues.

Okay I got it working,

I had to use xml simple, then I killed the first, and last tag of the xml,

and then the format was okay.
