Hello Monks!
I have an XML file to be parsed using XML::Twig. I am getting the following error when I use twig_roots. "Odd number of elements in anonymous hash at line 29.
The code partially does what I need without the root handler line.
This is what I have done so far. There are many things wrong with my code. The XML code is just a snippet of another similar XML file. The actual XML file I have to parse is very big and would be impossible to call out the children of 'Misc' by their names.
1) Does not work with twig_roots. I am basically looking to display only the elements under Misc.The twig root element is input by the user.
2) With Twig_roots, all my data is printed in one line instead of 6 ( 2 for each Actor). Or even 3 with each actors info in one line
3) I am not sure how to display my header elements just once. I am just printing it in two different files now.
Code and XML below!
use strict;
use warnings;
use XML::Twig;
my $start = time;
my $flag = 0;
open my $fout1, '>', "XMLTest1.csv";
open my $fout2, '>', "XMLTest2.csv";
my $twig = XML::Twig - > new(
twig_roots => {
'Misc' => 1, 'Profession' =>1,'Actor' =>1,'Age' =>1
},
twig_handlers => {
'Database' => sub {
my($twig, $el) = @_;
$twig - > purge;
},
'Database//*' => sub {
print $fout2 $_ - > tag, ",", unless(($_ - > has_children(
+'#ELT')) || ($flag = 1));
print $fout1 $_ - > text, ",", unless($_ - > has_children(
+'#ELT'));
$flag = 1;
}
}
);
$twig - > parsefile('Actors.xml');
my $duration = time - $start;
print "Execution time: $duration s\n";
My XML file is shown here. I am basically trying to display my data as
|Profession|Actor |Age|Music|TV|Music|TV|
|Actor |Ben Affleck|43 |none|Pearl Harbor|none|2001|
|Actor |Ben Affleck|43 |Jenny from the block|Wood Will Hunting|200
