Re: RAM, "

I wrote this code :

#!/usr/bin/perl
use strict;
use warnings;

for(my $i=351; $i<400; $i++){
my $filename = '/home/nikol123/indri-5.6/runquery/trec7_4collections.t
+xt';
open(my $file, '<', $filename) or die "open: $!";

while ( <$file> )
{
my @lines = split(/\n/, $filename);
foreach my $line (@lines) { 
 if ($line = '<query> <type>indri</type> <number>$i</number> <text>"_"
+</text> </query>')
{ 
my $param = "<parameters>
<index>/home/nikol123/indri-5.6/4collections</index>
print $line;
<fbDocs>10</fbDocs>
</parameters>";
print $param;
}}}}
[download]

but it's not functional as i get this

<parameters>
<index>/home/nikol123/indri-5.6/4collections</index>
print <query> <type>indri</type> <number>$i</number> <text>"_"</text> 
+</query>;
<fbDocs>10</fbDocs>
</parameters>
[download]

but i want due to for loop to read and write the line that contain the variable i from the my txt file ,in order to have the according text field, for example for i=351 to have

<parameters>
<index>/home/nikol123/indri-5.6/4collections</index>
<query> <type>indri</type> <number>351</number> <text>Falkland petrole
+um exploration</text> </query>;
<fbDocs>10</fbDocs>
</parameters>

Consider using an XML parser. eg XML:Twig. `#!perl use strict; use warnings; use XML::Twig; my $filename = 'trec7_4collections.txt'; our $num; my $fh; for $num (351..354){ open $fh,'>',$num.'.xml' or die "$!"; my $twig = XML::Twig->new( twig_handlers => { query => \&query }, pretty_print=>'indented' ); $twig->parsefile($filename); $twig->flush($fh); print "Created $num.xml\n"; } sub query { my( $twig, $e) = @_; my $n = $e->first_child_text('number'); $e->cut if ($n ne $num); }` [download] poj	[reply] [d/l]

XML:Twig

#!perl
use strict;
use warnings;
use XML::Twig;
my $filename = 'trec7_4collections.txt';

our $num;
my $fh;
for $num (351..354){
  open $fh,'>',$num.'.xml' or die "$!";
  my $twig = XML::Twig->new(
    twig_handlers => { query => \&query },
    pretty_print=>'indented'
  );
  $twig->parsefile($filename);
  $twig->flush($fh);
  print "Created $num.xml\n";
} 

sub query { 
  my( $twig, $e) = @_;
  my $n = $e->first_child_text('number');
  $e->cut if ($n ne $num);
}
