NAME
Catalyst::View::ContentNegotiation::XHTML - Adjusts the response
Content-Type header to application/xhtml+xml if the browser accepts it.
SYNOPSIS
package Catalyst::View::TT;
use Moose;
use namespace::clean -except => 'meta';
extends qw/Catalyst::View::TT/;
with qw/Catalyst::View::ContentNegotiation::XHTML/;
1;
DESCRIPTION
This is a simple Role which sets the response "Content-Type" to be
"application/xhtml+xml" if the users browser sends an "Accept" header
indicating that it is willing to process that MIME type.
Changing the "Content-Type" to "application/xhtml+xml" causes browsers
to interpret the page as XML, meaning that your markup must be well
formed.
CAVEATS
This is useful when you're developing your application, as you know that
all pages you view are parsed as XML, so any errors caused by your
markup not being well-formed will show up at once.
Whilst this module is has been tested against most popular browsers
including Internet Explorer, it may cause unexpected results on browsers
which do not properly support the "application/xhtml+xml" MIME type.
METHOD MODIFIERS
after process
Changes the response "Content-Type" if appropriate (from the requests
"Accept" header).
METHODS
pragmatic_accept
Some browsers (such as Internet Explorer) have a nasty way of sending
Accept */* and this claiming to support XHTML just as well as HTML.
Saving to a file on disk or opening with another application does count
as accepting, but it really should have a lower q value then text/html.
This sub takes a pragmatic approach and corrects this mistake by
modifying the Accept header before passing it to content negotiation.
ATTRIBUTES
variants
Returns an array ref of 3 part arrays, comprising name, priority, output
mime-type, which is used for the content negotiation algorithm.
PRIVATE METHODS
_build_variants
Returns the default variant attribute contents.

BUGS
Should be split into a base ContentNegotiation role which is consumed by
ContentNegotiation::XHTML.
