XML and PHP Simplified - Building an XML Reader

XML and PHP Simplified - Building an XML Reader: "In this article, we are going to build an application that will enable us to work with XML documents. Since we’ve covered quite a bit in the last couple of articles, we are going to use that knowledge to create this program. We've already looked at the program requirements in the previous article. To refresh our memories, I will provide its code here so we can work through it. The first page in the program is where we will select the XML document that we want to work with. Alternatively, you can choose to create your own XML document to work with."
