XML

The ShockScript language includes XML capabilities.

XML expressions

XML expressions by default are used for creating implementation-defined objects; however, when the inference type is XML or XMLList, XML expressions evaluate to one of these types.

package com.business.components {
    //
    public function AppBar():whack.ds.Node {
        return (
            <w:HGroup>
                <w:Button click&={trace("clicked!")}>button 1</w:Button>
            </w:HGroup>
        );
    }
}

package com.business.editor {
    //
    public function data(a:String):XML {
        return (
            <tag>{a}</tag>
        );
    }
}

const xn = XML(<tag/>);

Attributes

<t a/> is equivalent to <t a={true}/>. Accessing XML attributes can be directly done by the @ operator, as in xnode.@x.

Event handlers

Inline event handlers may be expressed as eventName&={statementList} as a shortcut to eventName={function(event){statementList}}, as in:

<w:Button click&={trace("clicked!")}>Click me</w:Button>

If the event has no parameters, then the attribute above is equivalent to eventName={function(){statementList}}.

Interpolation

<w:VGroup {params}>
    {undefined}
    {null}
    {node}
    {nodeList}
    {plainText}
    {number}
</w:VGroup>

Filtering

XML and XMLList implement the filter operator.

xnode.(*.@name == "Diantha")

Descendants

XML and XMLList implement the descendants operator.

xnode..tag
