I don't understand getting the references by class - I'm not sure how to
handle the return from getElementsByClassName - this doesn't seem to be a
simple array of objects.
I also tried a global search and replace like this as a test:
var searchRE = new RegExp('mb','gi');
var replace = 'xx';
for (var i=0;i<textNodes.snapshotLength;i++) {
var node = textNodes.snapshotItem(i);
node.data = node.data.replace(searchRE, replace);
}
And it did not appear to do anything. One problem I have is I simply don't
know how to output to the error console for debugging.
