To get inner text of HTML element I've been using:

function get_inner_text(node) {
     if (node.nodeType === 3) {
         return node.data;
     }

     var txt = '';

     node = node.firstChild;
     while (node) {
         txt += get_inner_text(node);
         node = node.nextSibling;
     }
     return txt.replace(/\s+/g, ' ');
}

However, I am thinking about simplifying it and instead of:

var str = get_inner_text(elm); // elm represent reference to the HTML 
element

I would use now:

var str = elm.textContent || elm.data || elm.innerText;

Is it a good approach? Any suggestions?
