SYNOPSIS
$html = HTML::RewriteAttributes->rewrite($html, sub {
my ($tag, $attr, $value) = @_;
# delete any attribute that mentions..
return if $value =~ /COBOL/i;
$value =~ s/\brocks\b/rules/g;
return $value;
});
# writing some HTML email I see..
$html = HTML::RewriteAttributes::Resources->rewrite($html, sub {
my $uri = shift;
my $content = render_template($uri);
my $cid = generate_cid_from($content);
$mime->attach($cid => content);
return "cid:$cid";
});
# up for some HTML::ResolveLink?
$html = HTML::RewriteAttributes::Links->rewrite($html, "http://search.cpan.org");
# or perhaps HTML::LinkExtor?
HTML::RewriteAttributes::Links->rewrite($html, sub {
my ($tag, $attr, $value) = @_;
push @links, $value;
$value;
});
DESCRIPTION
"HTML::RewriteAttributes" is designed for simple yet powerful HTML
attribute rewriting.
You simply specify a callback to run for each attribute and we do the
rest for you.
This module is designed to be subclassable to make handling special
cases eaiser. See the source for methods you can override.
METHODS
"new"
You don't need to call "new" explicitly - it's done in "rewrite". It
takes no arguments.
"rewrite" HTML, callback -> HTML
This is the main interface of the module. You pass in some HTML and a
callback, the callback is invoked potentially many times, and you get
back some similar HTML.
The callback receives as arguments the tag name, the attribute name,
and the attribute value (though subclasses may override this --
HTML::RewriteAttributes::Resources does). Return "undef" to remove the
attribute, or any other value to set the value of the attribute.

THANKS
Some code was inspired by, and tests borrowed from, Miyagawa's
HTML::ResolveLink.
