rows isn'ta good variable name as table and table section elements
have a rows collection, so may be confusing.

Why not use either DOM 3 textContent or IE innerText? e.g.
function getText (el) {
if (typeof el.textContent == 'string') return el.textContent;
if (typeof el.innerText == 'string') return el.innerText;
}
Or if you want to be "Prototypeis":
Element.addMethods({
getText: function(element) {
element = $(element);
if (typeof element.textContent == 'string') {
return element.textContent;
}
if (typeof element.innerText == 'string') {
return element.innerText;
}
}
});
Table rows have a cells collection that contains all the cells in the
row, so if you want the content of the first cell:
var value = rows[i].cells[0].getText();
