Help with perl script.
Hi,
I have one folder that contains more number of xml files and extract some specific information form xml files. I used libxml to extract wanted information one xml and i succeded but now how can i extract from folder and each xml file using perl script. i tried like this for one xml file
Code:
use warnings;
 use strict;
 use XML::LibXML::Reader;
  my $file;
 open( $file, 'formal.xml');
 my $reader = XML::LibXML::Reader->new( IO => $file ) or die ("unable to open file");
     my %hash;
 while ($reader->nextElement( 'nuber' ) ) {
 
 my $Number = $reader->readInnerXml();
 
 $reader->nextElement( 'data' ); 
 my $information = $reader->readOuterXml(); 
 
 $nums{$Number}= $information;
 
 print( "  NUMBER:$Number\n" );
     print( " Information:$information\n" );
 
    }
  print my $num=keys%hash;
 close($file);
