I have a catalog in XML format: <?xml version="1.0" encoding="iso-8859-1" ?> <catalog> <book> ... <book> <book> ... <book> ... </catalog> Now I want to add another book, which I have as a SimpleXMLElement: $book = new SimpleXMLElement($string); where $string reads <book> ... <book> Can I add this new entry to the catalog using SimpleXML functions, or do I have to introduce a DOMDocument? As may be obvious, I am very new to PHP programming; and advice or suggestions gratefully received. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
