SimpleXML end of element/tag error

I am using simple xml to parse an xml file, the program parses the file and produces an error at the end of the foreach loop when it reaches the end of the tag, it tries to look for an element/tag when there is none and produces an error "Call to a member function attributes() on a non-object" the foreach loop looks like this foreach($xml->CS as $CS) { //processing takes place here } when there are no more CS it fires an error How can i detect when there are no more elements/tags to parse and handle it? cheers --------------------------------- It's here!
