Is there any reason why I should pick JSON over XML, or vice-versa if both are available? Tips for optimizing performance when dealing with data feeds are also appreciated!

When it comes to PHP the one reason I choose XML over JSON is because even in PHP 5 there is no officially supported API for traversal. You can encode, and you can decode, and that is it. There is no validation, no efficient way to traverse key/value pairs, and all-in-all, very little support for it. Don’t get me wrong, you can just use a foreach looping structure, but it really is cumbersome. JSON was touted as a great data-interchange format because JavaScript has an easy time understanding the lexical structure. So when you go from PHP to JavaScript, it is great, but when you go from JavaScript to PHP, or PHP to PHP, then JSON is not the best choice for data interchange.
