So, I tried to use a variable to return the values from the XPath, and it's not liking it.. I get an invalid query error. Here is the subroutine I'm using. I must be missing something. I added a few statements to help me see what was happening. The goal is for the XPaths to come from a configuration file (as there are about a dozen, and there are other formats that will be added in the future so there may be hundreds ultimatley) rather than hard coded, but for testing and development I'm doing it this way.

$twig = XML::Twig::XPath->new();
$twig->parsefile($xmlfile);
$root = $twig->root;

$XPV='//Party[@id=//Relation[child::RelationRoleCode[@tc="37"]]/@Relat
+edObjectID]/Producer/CarrierAppointment/CompanyProducerID';
my $retval1 = get_xpath_value($XPV);
$XPV='//OLifE/Party[@id=//OLifE/Relation[RelationRoleCode@tc=8]/@Relat
+edObjectID]/Person/FirstName';
my $retval2 = get_xpath_value($XPV);
print "CompanyProducerID: $retval1 \nFirstName: $retval2\n";

sub get_xpath_value {

   my ($argvalx) = @_;
   print "argvalx: $argvalx\n";
   my $xpath = "q!" . $argvalx . "!";
   print "doing XPATH query on $xpath\n";
   my @nodes = $root->findnodes($xpath);
   for (@nodes){
     print $_->text;
     return $_->text;
   }
}


./twig4.pl -xmlfile=a2b9f375-51fe-41a1-86ab-069561517890.xml

Invalid query somewhere around here (I think)
