Hi I wanted to know how to append an XML tag in a newly created Appended Child Node?
Here is what I have,
$newNode = $xml->createDocumentFragment();
$reCreateOldNode = $xml->createElement("myNewChild");
$newNode->appendChild($reCreateOldNode); // This is Newly Appended Child
while ($node->firstChild) {
$match->nodeValue = "";
$newNode->appendChild($node->firstChild);
$newNode->appendXML($actionOutput); // I want to Append the XML to $newNode->myNewChild
}
$node->parentNode->replaceChild($newNode, $node);
This is the newly created Child,
$newNode->appendChild($reCreateOldNode);
And I want to Append the XML that I have created to$newNode->myNewChild
not on$newNode
directly.
The actual purpose of a document fragment is to allow you to treat a list of nodes (elements, text nodes, comments...) as a single node and use them as an argument to the DOM methods. You only want to append a single node (and its descendants) - no need to append this node to a fragment.
In PHP the document fragment can parse an XML fragment string. So you can use it to parse a string as an XML snippet and then append it to a DOM node. This fragment will be appended to new node.
$document = new DOMDocument();
$document->loadXML('<old>sample<foo/></old>');
$node = $document->documentElement;
// create the new element and store it in a variable
$newNode = $document->createElement('new');
// move over all the children from "old" $node
while ($childNode = $node->firstChild) {
$newNode->appendChild($childNode);
}
// create the fragment for the XML snippet
$fragment = $document->createDocumentFragment();
$fragment->appendXML('<tag/>text');
// append the nodes from the snippet to the new element
$newNode->appendChild($fragment);
$node->parentNode->replaceChild($newNode, $node);
echo $document->saveXML();
Output:
<?xml version="1.0"?>
<new>sample<foo/><tag/>text</new>
