( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Dear Monks,

I have an error "Out of memory" while parsing large (100 Mb) XML file

use strict; use warnings; use XML::Twig; my $twig=XML::Twig->new(); my $data = XML::Twig->new->parsefile("divisionhouserooms-v3.xml")->sim +plify( keyattr => []); my @good_division_numbers = qw( 30 31 32 35 38 ); foreach my $property ( @{ $data->{DivisionHouseRoom}}) { my $house_code = $property->{HouseCode}; print $house_code, "\n"; my $amount_of_bedrooms = 0; foreach my $division ( @{ $property->{Divisions}->{Division} } ) { next unless grep { $_ eq $division->{DivisionNumber} } @good_d +ivision_numbers; $amount_of_bedrooms += $division->{DivisionQuantity}; } open my $fh, ">>", "Result.csv" or die $!; print $fh join("\t", $house_code, $amount_of_bedrooms), "\n"; close $fh; }

What i can do to fix this error issue?

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
