=head1 NAME
HTML::HTML5::Parser::Error - an error that occurred during parsing
=head1 DESCRIPTION
The C<error_handler> and C<errors> methods of C<HTML::HTML5::Parser> generate
C<HTML::HTML5::Parser::Error> objects.
C<HTML::HTML5::Parser::Error> overloads stringification, so can be printed,
matched against regular expressions, etc.
Note that L<HTML::HTML5::Parser> is not a validation tool, and there are many
classes of error that it does not care about, so will not raise.
=head2 Constructor
=over
=item C<< new(level=>$level, type=>$type, token=>$token, ...) >>
Constructs a new C<HTML::HTML5::Parser::Error> object.
=back
=head2 Methods
=over
=item C<level>
Returns the level of error. ('MUST', 'SHOULD', 'WARN', 'INFO' or undef.)
=item C<layer>
Returns the parsing layer involved, often undef. e.g. 'encode'.
=item C<type>
Returns the type of error as a string.
=item C<tag_name>
Returns the tag name (if any).
=item C<source_line>
($line, $col) = $error->source_line();
$line = $error->source_line;
In scalar context, C<source_line> returns the line number of the
source code that triggered the error.
In list context, returns a line/column pair. (Tab characters count as
one column, not eight.)
=item C<to_string>
Returns a friendly error string.
