You could give the table a unique id and then use the getElementsByTagName function:

var table = document.getElementById('tableId');
if (table == null) return;
var divs = table.getElementsByTagName('div');
for (var i = 0; i < divs.length; i++) {
    var div = divs[i];
    if (div.lang == '1') {
        alert(div);
    }
}
