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.

SEE ALSO ^

BUGS ^

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