In a new blog post today Sudheer Satyanarayana shows how to take a few simple lines of code (seven to be exact) and create a simple XML/RSS reader he used to pull in weather data for a simple application.
Today, I was looking for a quick way to get the current weather information on my computer. There are so many websites out there that offer the information. But I was looking for a program I could permanently install on my computer and launch it whenever I want to lookup the weather information. [...] I wrote a program to print the weather information in 7 lines of PHP code. I have published this program on Code Album github repository. You can grab it and use it.
He chose a Yahoo feed to get the weather information from their service. He includes the base code to make the request via a cURL connection and parsing it into a SimpleXML object to pull out the needed info.
