哪个<ul>最多<li> s？

I simply want to search that which <ul> has the most <li>? How would I do that?

Like there's an html page containing

<ul>
<li>1</li>
</ul>

<ul>
<li>1</li>
<li>1</li>
<li>1</li>
</ul>

<ul>
<li>1</li>
<li>1</li>
</ul>

Now then I want to show <ul> number 2 has the most <li>s. It can be done via PHP.

Thanks

The best solution is to use jQuery for this - it may loo like this

var largestUl = null;

$('ul').each(function () {
    if (largestUl == null) {
        largestUl = this;
    } else {
        if ($(largestUl, 'li').length > $(largestUl, 'li').length) {
            largestUl = this;
        }
    }
});
