The DOM is a very exciting set of functionality for web pages, but most of the attention has been drawn by the standard DOM functionality. Many developers are unaware that the DOM has much more to offer than just createElement() and appendChild(); DOM ranges are a very powerful tool for dynamic web page manipulation.

A range can be used to select a section of a document regardless of node boundaries (note that the selection occurs behind the scenes and cannot be seen by the user). Ranges are helpful when regular DOM manipulation isn't specific enough to change a document.

DOM Level 2 defines a method called createRange() to, well, create ranges. In DOM-compliant browsers (not Internet Explorer, by the way), this method belongs to the document object, so a new range can be created like this:

var oRange = document.createRange();
