Im trying to save a specific node instead of the full xml file, but I get error.Catchable fatal error: Argument 1 passed to DOMDocument::saveXML() must be an instance of DOMNode, instance of DOMNodeList given in php\corrdination.php on line 31I'm following the doom documentation but since I don't create new element and only read from an already created xml file, it wont work with creating new elements.My line 31 is\[code\]$resultX = $xpath->query('/stickers/sticker[id="200"]/position/x'); \[/code\]And when im trying to save only the changed node i write.\[code\]echo $xml->saveXML($resultX);\[/code\]Any suggestion on how to do it ?This is my whole php file.\[code\] $xml = new DOMDocument(); $xml->formatOutput = TRUE; $xml->preserveWhiteSpace = FALSE; $xml->load('../stickers.xml'); $xpath = new DOMXPath($xml); $resultX = $xpath->query('/stickers/sticker[id="200"]/position/x'); $resultX->item(0)->nodeValue = "http://stackoverflow.com/questions/15586579/150"; echo $xml->saveXML($resultX);\[/code\]If I only \[code\]echo $xml->saveXML();\[/code\]The query works but as I said, it saves the whole node structure.XML file:\[code\]<stickers> <sticker> <position> <x>0</x> </position> <text>Hello world </text> <id>200</id> </sticker> </stickers>\[/code\]Thanks
