If you have such a solution, I would love to see it. If you would like an example, I might want to add the item: <book> <author>Smith, J</author> <title>PHP for dummies</title> <publisher>OUP</publisher> </book> My solution, for what it is worth, is something like ------------------------------------- $docA = new DOMDocument; $docB = new DOMDocument; $docB->loadXML($book); $xpath = new DOMXPath($docB); $nodes = $xpath->query('//catalog/book'); foreach($nodes as $n) { $new = $docA->importNode($n, true); $docA->documentElement->appendChild($new); } $output = $docA->save("/tmp/catalog.xml"); ------------------------------------- > Timothy Murphy wrote: >> 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? -- 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
