    <p>Extracts elements from an html document held in <code>msg.payload</code> using a selector.</p>
    <p>If left blank the selector may be set dynamically by passing in <code>msg.select</code> along with the <code>msg.payload</code>.
    <p>The selector uses <a href="https://github.com/cheeriojs/cheerio/blob/master/Readme.md" target="_new">Cheerio</a>
     which uses the <a href="https://github.com/fb55/CSSselect#user-content-supported-selectors" target="_new">CSS selector</a> syntax.</p>
    <p>The result can be either a single message with a payload containing an array of the matched elements, or multiple
       messages that each contain a matched element.</p>
