( #3333=superdoc: print w/ replies, xml ) Need Help??

I have successfully read an xml file, gotten some info and stored it in a variable. Then I used the information in the variable to system grep another xml file, and store that in a variable. I want to use XPATH to get some info from that second XML, but can't. It gives the following errors:

Use of uninitialized value in subroutine entry at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/XML/Parser/Expat.pm line 474.

and ..

no element found at line 1, column 0, byte -1: 28^ 7157840 at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/XML/Parser.pm line 187

Here is the code:

#!/usr/bin/perl -w use strict; use warnings; use XML::XPath; use MIME::Lite::TT; use File::Copy; use File::Find; use File::Grep qw( fgrep fmap fdo ); my $file = '/home/jramirez/20120811_XML_Reader_837/test.xml'; my $xp = XML::XPath->new(filename => $file); my $icncount = 1; my $transactioncount = 0; my $billedamount = 0; my $PayerName3 = ''; my $ICN = ''; my $BillingProvider = ''; my $line = ''; my $cmd = ''; my $Name = ''; my $xmlpath = ''; my $xmlname = ''; print $file . "\n"; print $xp . "\n"; foreach my $InterchangeControlHeader ($xp->find('//InterchangeControlH +eader')->get_nodelist){ my $InterchangeControlNumber13 = $InterchangeControlHeader->find(' +@InterchangeControlNumber13')->string_value; $ICN = $InterchangeControlNumber13 } foreach my $Transaction837P ($xp->find('//Transaction837P')->get_nodel +ist){ my $BillingProviderIdentifier9 = $Transaction837P->find('BillingPr +oviderHierarchicalLevelLoop/BillingProviderNameLoop/BillingProviderNa +me/@BillingProviderIdentifier9')->string_value; $BillingProvider = $BillingProviderIdentifier9; $PayerName3 = $Transaction837P->find('SubscriberHierarchicalLevelL +oop/PayerNameLoop/PayerName/@PayerName3')->string_value; $transactioncount++; } foreach my $ServiceLineNumberLoop ($xp->find('//ServiceLineNumberLoop' +)->get_nodelist){ my $AssignedNumberLine = $ServiceLineNumberLoop->find('Service +LineNumber/@AssignedNumber1')->string_value; my $LineItemChargeAmount2 = $ServiceLineNumberLoop->find('Prof +essionalService/@LineItemChargeAmount2')->string_value; if ($LineItemChargeAmount2 eq '') { $LineItemChargeAmount2 = 0; } $billedamount += $LineItemChargeAmount2; } print 'Billing Provider: ' . $BillingProvider . "\n"; print 'ICN: ' . $ICN . "\n"; print 'Payer: ' . $PayerName3 . "\n"; print 'Total Number Invoices: ' . $transactioncount . "\n"; print 'Total Billed: ' . $billedamount . "\n"; my $SESXML = `find /home/jramirez/PayerDownload/SES/backup/*xml -maxde +pth 1 -type f -exec grep -q $ICN '{}' ';' -exec echo '{}' ';' `; chomp $SESXML; my $sesxp = XML::XPath->new(filename => $SESXML); foreach my $interchange ($sesxp->find('//Interchange')->get_nodelist){ $Name = $interchange->find('Accept/@Name')->string_value; print $Name . "\n"; print "I think we got 'em, but we dont!" . "\n"; }

The objective is to read the first xml, gather unique identifiers that help me find the second xml. Once the second xml is found, i want to XPATH the info I need from it into variables. Then I'll use the variables to generate a simple txt report.

I printed out the $xp and $sesxp variables and noted that they have the same value, and guess I should clear that? can't find how to, must be googling the wrong terms.

I humbly ask for help.
