Checks if $tag/$attribute tuple matches "%HTML::Linear::Path::groupby".

GLOBALS ^

%HTML::Linear::Path::groupby

Tags/attributes significant as XPath filters. @class/@id are the most obvious; we also use meta/@property, input/@name and several others.

%HTML::Linear::Path::tag_weight

Table of HTML tag weights. Borrowed from TexNet32 - WWW filters.

%HTML::Linear::Path::xpath_wrap

Wrap XPath components to produce fancy syntax highlight.

The format is:

    (
        array       => ['' => ''],
        attribute   => ['' => ''],
        equal       => ['' => ''],
        number      => ['' => ''],
        separator   => ['' => ''],
        sigil       => ['' => ''],
        tag         => ['' => ''],
        value       => ['' => ''],
    )

There are several pre-defined schemes at HTML::Linear::Path::Colors.
