Lorna Mitchell has a new post to her blog with a quick example of how to get namespaced values with SimpleXML out of a properly formatted XML file.
Recently I was working with some google APIs and needed to retrieve some namespaced elements from the result set. This confused me more than I expected it to so here's my code for the next time I need it (and if you use it too, then great!) I was reading from their analytics data feed API, this returns a few key fields and then multiple
tags, each with namespaced children.
