NAME ^

XML::XSS::StyleAttribute - Style attribute for XML::XSS stylesheet rule

VERSION ^

version 0.3.4

SYNOPSIS ^

    use XML::XSS;

    my $xss = XML::XSS->new;
    my $attribute = $xss->get('chapter')->pre;

    $attribute->set_value( '<div class="chapter">' );

DESCRIPTION ^

The XML::XSS::StyleAttribute objects are the building blocks of the document transformation. They can be assigned a string, which is inserted verbatim in the rendered document

    $xss->get('chapter')->set_pre( '<div class="chapter">' );

or a sub reference, which return value is inserted in the rendered document

    $xss->get('clock')->set_pre( sub { return "date and time are: " .  localtime } );

Upon execution, the sub references will be passed three parameters: the invoking rule, the XML::LibXML::Node object currently rendered and the arguments ref given to render().

    $xss->set( 'div' => {
        intro => sub {
            my ( $self, $node, $args ) = @_;
            my @para = $node->findnodes( '@para' );
            return "<p>node has " . @para . " para child nodes.</p>";
        }
    } );

OVERLOADING ^

*=

Assigns the right value to the attribue.

    $xss.'chapter'.'pre' *= "<div class='chapter'>";

is equivalent to

    $xss->set( chapter => { pre => "<div class='chapter'>" } );

x=

Similar to '*=', but considers the right side as a template and converts it via xsst.

    $xss.'chapter'.'pre' x= q{
        <div class="chapter">
            <% $r->stylesheet->stash{chapter_nbr}++ %>
    };

is equivalent to

    $xss->set( 'chapter' => { pre => xsst( <<'END_TEMPLATE' ) } );
        <div class="chapter">
            <% $r->stylesheet->stash{chapter_nbr}++ %>
    END_TEMPLATE

ATTRIBUTES ^

value

The string or sub reference used by the style attribute.

    # long way
    $xss->get('chapter')->pre->set_value( '<div class="chapter">' );

    # short way
    $xss->set( chapter => { pre => '<div class="chapter">' } );

    # shortest way
    $xss.'chapter'.'pre' *= '<div class="chapter">';
