Note Submitter: Ian Zepp ---- For generating XML, SimpleXML may not be the best choice, depending on your performance requirements: I needed to create a context stream (such as "logging://info") in order to push logging messages from a PHP webserver to an Enterprise Service Bus for routing and auditing. Since this is logging, high-traffic is expected and high performance XML generation is required. Unfortunately, SimpleXML just was not up to the task, although not nearly as back as using the XML_Serializer library.
