Alejandro Gervasio has finished up his series on DevShed looking at working with the DOM extension in PHP5 with this new article, a look at parsing child nodes.

In this last chapter of the series, I'm going to teach you how to handle the child nodes of an XML document by way of two simple methods, called hasChildNode() and removeChild() respectively. So let's not waste any more time in preliminaries and learn how to use them in a helpful way.

They review some of the concepts mentioned previously before moving ahead to the use of the hasChildNodes and removeChild methods to check for children and get rid of only certain ones.
