[RESOLVED] Trouble Appending to XML File

[sandthipe]

I am able to append an element onto the root of my XML document, but not onto a child element of the root. Example:

<hobbies>
   <boardgames></>
   <sports></>
   <stamps></>
</hobbies>

Using the code below, I can append a new element to the <hobbies> root element, but I cannot figure how to append a new element to one of the sub-elements (boardgames, sports, or stamps).

<?php
	$dom = new DomDocument();
	$dom -> load("hobbies.xml");
	$newHobby = $dom -> createElement("music");
	$dom -> documentElement -> appendChild ($newHobby);
	$dom -> save("newimages.xml");
?>

Any Ideas on how I might create a new element under a non-root element?

Thanks - Chris

Locate the element you want (with the DomDocument/DomElement get_* methods, or an XPath query) and then use that element's AppendChild method.

$xml = <<<EOX
<hobbies>
   <boardgames></boardgames>
   <sports></sports>
   <stamps></stamps>
</hobbies>
EOX;
	$dom = new DomDocument();
	$dom->loadXML($xml);

// We'll pick a boardgame.
$newGame = $dom->createElement("Ludo");
// So find the boardgames element(s)
// We get a list of elements, but we just want the 0th:
$boardgames = $dom->getElementsByTagName('boardgames')->item(0);
// And append.
$boardgames->appendChild ($newGame);

echo	$dom->saveXML();
