Validating XML file with XML::Schematron::LibXSLT

hiruzen has asked for the wisdom of the Perl Monks concerning the following question:

I want to verify XML file using XML::Schematron::LibXSLT here is code i tried which uses .sch schemafile and XML file as argument

use XML::Schematron::LibXSLT;

my $schema_file = $ARGV[0];
my $xml_file    = $ARGV[1];

die "Usage: perl schematron.pl schemafile XMLfile.\n"
    unless defined $schema_file and defined $xml_file;

my $tron = XML::Schematron::LibXSLT->new();

$tron->schema($schema_file);
my $ret = $tron->verify($xml_file);

print $ret . "\n";
[download]

It is giving error Can't locate object method "new" via package "XML::Schematron::LibXSLT" at schematron.pl line 14. which tell module don't have new method. May be module is updated.

use XML::Schematron;

my $pseudotron = XML::Schematron->new_with_traits( traits => ['LibXSLT
+'], schema => "$schema_file");
my $messages = $pseudotron->verify($xml_file);

print "$messages\n";
[download]

But it dosen't print anything. Don't know what is wrong!
Also at https://metacpan.org/pod/XML::Schematron::LibXSLT Synopsis, 2nd and 3rd use are giving same error.
The same problem is also posted on stackoverflow.com at StackOverflow

`use warnings; use strict;` [download] ("Can't locate object method "new"" strongly suggests that XML::Schematron::LibXSLT didn't load properly, but without the warnings, you won't find out why...)	[reply] [d/l]

Hi hiruzen, I have not use XML::Schematron::LibXSLT before, but looking at the documentation on metacpan, I think you are not using the module as stated. In the Synopsis, I didn't see anything like: `... = XML::Schematron::LibXSLT->new() # empty new method` [download] What I can see is `... = XML::Schematron::LibXSLT->new(schema => 'my_schema.xml') # note that` Then did you notice this: `use XML::Schematron; my $pseudotron = XML::Schematron->>new_with_traits( traits => ['LibXSL +T'], schema => 'my_schema.xml');` [download] Note the ->>, but you used -> Maybe if you make those changes it would work. Just what I observed. Update: Note that '->>' as specified in the module documentation is actually a typo. Noted by AM and the OP of this thread. I only wonder why that was not spotted for such a long time atleast about 24 months now. If you tell me, I'll forget. If you show me, I'll remember. if you involve me, I'll understand. --- Author unknown to me	[reply] [d/l] [select]

Maybe but I wonder why that it has not been reported. Or why the Author has not seen it for about 4 years now, though it looks like there is not activity on that module for about 24 months now If you tell me, I'll forget. If you show me, I'll remember. if you involve me, I'll understand. --- Author unknown to me	[reply]

Using "->>" it gives following error: `syntax error at schematron.pl line 27, near "->>"<br />Global symbol " +$pseudotron" requires explicit package name at schematron.pl line 28.` [download]	[reply] [d/l]

Did you run the test suite for XML::Schematron and did it pass?	[reply]
Re^2: Validating XML file with XML::Schematron::LibXSLT by hiruzen (Novice) on Jul 28, 2014 at 08:25 UTC
Yes. It is passed with following code but with no error messages. `use XML::Schematron; my $pseudotron = XML::Schematron->new_with_traits( traits => ['LibXSLT +'], schema => "$schema_file"); my $messages = $pseudotron->verify($xml_file); print "$messages\n";` [download]	[reply] [d/l]

"Test suite" means https://metacpan.org/source/KHAMPTON/XML-Schematron-1.09/t/001basic.t, the stuff that runs before you install module	[reply]
