How do I add new elements to XML using PHP DOM deeper than the root?
adding content to an XML file at the document root, but I really need to do it deeper than that.
You're not adding content anywhere at the moment! You create <title> and <link> element nodes with text in, then you do nothing with them. You should be passing them into ‘appendChild’ on the <item> element node (which also you are currently creating and immediately throwing away by not assigning it to a variable).
Here's a starting-point:
$screenshots= $dom->getElementsByTagName("screenshots")[0];
$title= $dom->createElement("title");
$title->appendChild($dom->createTextNode($newshottitle));
$item= $dom->createElement("item");
$item->appendChild($title);
$screenshots->appendChild($item);

All of the examples I can find online about this involve simply adding content to an XML file at the document root, but I really need to do it deeper than that.
My XML file is simple, I have:
<?xml v1 etc> <channel> <screenshots> <item> <title>Image Title</title> <link>www.link.com/image.jpg</link> </item> </screenshots> </channel>
All I want to be able to do is add new "item" elements, each with a title and link. I know I need to be using PHP DOM, but I'm stumped as to how to code it so that it adds data within "screenshots" rather than overwriting the whole document. I have a suspicion I may need to use XPath too, but I have no idea how!
The code I have pieced together from online examples looks like this (but I'm certain it's wrong)
$newshottitle = "My new screenshot"; $newshotlink = "http://www.image.com/image.jpg"; $dom = newDomDocument; $dom->formatOutput = true; $dom->load("../xml/screenshots.xml"); $dom->getElementsByTagName("screenshots"); $t = $dom->createElement("item"); $t = $dom->createElement("title"); $t->appendChild($dom->createTextNode("$newshottitle")); $l = $dom->createElement("link"); $l->appendChild($dom->createTextNode("$newshotlink")); $dom->save("../xml/screenshots.xml");
