He was cast opposite Anthony Hopkins in the 1994 drama Legends of the Fall, which earned him his first Golden Globe nomination. In 1995 he gave critically acclaimed performances in the crime thriller Seven and the science fiction film 12 Monkeys, the latter securing him a Golden Globe Award for Best Supporting Actor and an Academy Award nomination. Four years later, in 1999, Pitt starred in the cult hit Fight Club. He then starred in the major international hit as Rusty Ryan in Ocean's Eleven (2001) and its sequels, Ocean's Twelve (2004) and Ocean's Thirteen (2007).

The SimpleXML extension provides is a simple way of getting an XML element's name and text.
Compared to DOM or the Expat parser, SimpleXML just takes a few lines of code to read text data from an XML element.
SimpleXML converts the XML document (or XML string) into an object, like this:
Elements are converted to single attributes of the SimpleXMLElement object. When there's more than one element on one level, they are placed inside an array
Attributes are accessed using associative arrays, where an index corresponds to the attribute name
Text inside elements is converted to strings. If an element has more than one text node, they will be arranged in the order they are found
