I'm trying to handle the data coming from the Adwords API with XML::Simple, which seems to be a decent choice for it, but I can't seem to grab the values that I need, which are just so deep into the XML. I'm not sure where I'm wrong, but maybe you can help: 
#!/usr/bin/perl -w
use strict;
use XML::Simple;
use Data::Dumper;

my $content = XMLin(qq|
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envel
+ope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://

|);

print "... $content->{'soapenv:Envelope'}{'soapenv:Body'}{'getKeywordV
+ariationsResponse'}{'getKeywordVariationsReturn'}{'moreSpecific'}[0]-
+>{'text'} ...\n";
#print Dumper(\$content);

This returns me nothing, and I even get the fun uninitialized statement: 
Use of uninitialized value in concatenation (.) or string at xmlparser
+.pl line 54.

Any ideas? Obviously I need what's in the text, advertiserCompetitionScale, and searchVolume tags, and I need to iterate through each occurrence. Any ideas?
