In jQuery, how would I descend as far as possible into the HTML tree?
For simplicity, I only have one path going downward.
(related but bonus: how do I find the deepest element with multiple downward paths?)
<html>
<table id="table0">
<tr>
<td id="cell0">
<div class"simple"> I want to change this information </div>
</td>
</tr>
</table>
</html>
I want to change the innermost HTML of the cell named cell0 but I don't necessarily know the names of all the classes inside. Is it possible to select this far without knowing these names?
Thanks much!

Use innerHTML property of an element to get or set HTML contained within the element. The innerHTML property returns the current HTML source of the element, including any change that has been made since the page was loaded.
We can find and click elements by title in Selenium webdriver. An element can be identified with a title attribute with xpath or css selector. With the xpath, the expression should be //tagname[@title='value']. In css, the expression should be tagname[title='value'].
The * selector selects all elements. The * selector can also select all elements inside another element (See "More Examples").
I'd do this through a single recursive function:
// Returns object containing depth and element
// like this: {depth: 2, element: [object]}
function findDeepestChild(parent) {
var result = {depth: 0, element: parent};
parent.children().each(
function(idx) {
var child = $(this);
var childResult = findDeepestChild(child);
if (childResult.depth + 1 > result.depth) {
result = {
depth: 1 + childResult.depth,
element: childResult.element};
}
}
);
return result;
}
