What does this regexp(rinlinejQuery) mean in jQuery?
<pre><code>var rinlinejQuery = / jQuery\d+="(?:\d+|null)"/g,

html: function( value ) {
        if ( value === undefined ) {
            return this[0] &amp;&amp; this[0].nodeType === 1 ?
                this[0].innerHTML.replace(rinlinejQuery, "") :
                null;

        // See if we can take a shortcut and just use innerHTML
        }
</code></pre>

<p>Does it match code such as <code>jQuery11="11"</code>?</p>

<p>And why is it needed in the <code>html()</code> function?</p>
