The extension is not experimental anymore ;) And the formatting is not lost. you didn't provide any ;) The DOM Extension doesn't make any assumptions about the formatting of your XML document (or correctly said, it doesn't insert whitespace "automagically" ) but you can try to set the property formatOutput just before saveXML: $doc->formatOutput = true; Never tested, but should work chregu > TIA for any advice...
