how to count the number of elements in a web page

[sumire]

Hi,

I want to count the number of elements in a web page.
(ex. how many '<li>' in a web page?)

if I do with JavaScript, I do:
$(function() {
var size = $('li').length;
alert(size);
});

I want to do same as this by blue prism.
Please tell me how to do.

Thanks in advance
