How can I easily test if XML file is well-formed in Perl?

Question

I know there are quite some threads talking about validating XML file against its XML schema, such as : validate-xml-using-libxml and xml-schema-validation-with-relaxng

So if there is a simple Perl module on CPAN that can test this with minimal code, then that would be very fantastic to know.

Answer 1

You can simply use XML::Parser.

Note that your question title refers to being well-formatted (well-formed?) whereas the body refers to validation. If you want to validate (against a schema) check out XML::Validator::Schema.

Answer 2

Since XML::Parser will die if a parsing error occurs, try this for minimal code:

XML::Parser->new->parse($xml);

Answer 3

I'd use Test::XML. It gives you methods is_xml, is_well_formed_xml.

Answer 4

There's XML::Compile, but it's not easy until you learn to use the module.
