I think XPath is the primary option for traversing XML-like documents. With RegExp, it will be up to you to handle the different forms of writing a tag (with multiple spaces, double quotes, single quotes, no quotes, in one line, in multi-lines, with inner data, without inner data, etc).

See how powerfull it can be at http://www.w3schools.com/xpath/.
