xml::validate::base
XML::Validate::Base(3pm) User Contributed Perl Documentation XML::Validate::Base(3pm)
NAME
XML::Validate::Base - Abstract base class to be used by XML::Validate modules
SYNOPSIS
use XML::Validate::Base;
sub new {
... override new ...
}
sub validate {
... override validate ...
}
DESCRIPTION
XML::Validate::Base provides a base class with helpful subs for real XML::Validate modules.
METHODS
new(%options)
Constructs a new validator. This method must be overridden.
validate($xml)
Parses and validates $xml. Returns a true value on success, undef on failure. This method must be overridden.
options
An accessor for the options hashref.
set_options($supplied_options,$valid_options)
Sets the options for the validator. $supplied_options and $valid_options are hash refs containing respectively the options supplied to
the constructor and the valid options for validator along with their default values.
If the supplied options hash ref contains an option not listed in valid options, this sub throws an exception.
last_error
Returns the error from the last validate call. This is a hash ref with the following fields:
o message
o line
o column
Note that the error gets cleared at the beginning of each "validate" call.
add_error($error)
Stores $error for retrieval by last_error. $error should be a hash ref.
clear_errors
Clears any errors held by the validator.
