In this sample program I will show you how to select a value from a drop down menu in HTML and extract the data in an XML file. This will be my first time to write a program that uses XML and PHP. According to Wikipedia.org XML is defined as Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. It is defined by the W3C's XML 1.0 Specification and by several other related specifications, all of which are free open standards.
The code is very easy to follow and understand I hope you will find my work useful in your programming projects and assignments. If you have some questions please send me an email at jakerpomperada@yahoo.com and jakerpomperada@gmail.com.
People here in the Philippines can contact me at my mobile number 09173084360.
Thank you very much and Happy Programming.
