This is my sample xml file (snipped version of deployment plan for weblogic application).
<?xml version="1.0" encoding="UTF-8"?>
<deployment-plan>
<application-name>ear-my-service</application-name>
<variable-definition>
<variable>
<name>characteristics</name>
<value>myTestEAR</value>
</variable>
<variable>
<name>Url</name>
<value>ABC</value>
</variable>
<variable>
<name>time</name>
<value>300</value>
</variable>
</variable-definition>
</deployment-plan>
I want to update the value when the name is characteristics. I looked around and put together this script.
#!/usr/bin/perl
use strict;
use warnings;
use XML::Twig;
my $data = shift ||die $!;
my $t= XML::Twig->new(
twig_handlers => {
q{project[string(name) =~ /\bcharacteristics\b/]/value} => \&value,
},
pretty_print => 'indented',
);
$t->parsefile( $data );
$t->print;
sub value {
my ($twig, $value) = @_;
$value->set_text("myTestEAR_Modified");
}
However, it doesn't change the value to myTestEAR_Modified. Am I doing it incorrectly?
The tag name in the XML is variable
, not project
, replace it in the condition (q{variable[string(name)...
) and it will work.
