Message:

I tried to parse an XML & delete a node "displayTextFlow" from the XML. Below is my code:

$filePath = file_get_contents('sample.xml');

$xml = new SimpleXMLIterator($filePath);

$iterator = new RecursiveIteratorIterator($xml, RecursiveIteratorIterator::SELF_FIRST);

foreach ($iterator as $key => $element) {

    if ($key == 'displayTextFlow') {

        unset($iterator[$key]);

    }

}

$finalXML = $xml->asXML();

print_r($finalXML);

exit;

In my sample XML, I'm not sure about the exact place for the tag "displayTextFlow". It may come in any other place. So I need to write a code to parse the XML & delete the tag "displayTextFlow" in all the places
Note: I need to do it only using SimpleXMLIterator.

Please check the sample XML:

<?xml version="1.0"?>

My Answer:
You can achieve this by using a recursive function to iterate through all the nodes in the XML and delete the "displayTextFlow" nodes. Here's an updated version of your code:

php
$filePath = file_get_contents('sample.xml');
$xml = new SimpleXMLElement($filePath);

function deleteNode($node) {
foreach ($node->children() as $child) {
if ($child->getName() == 'displayTextFlow') {
unset($child[0]);
}
deleteNode($child);
}
}

deleteNode($xml);

$finalXML = $xml->asXML();
print_r($finalXML);
exit;


This code defines a recursive function `deleteNode` that iterates through all the children of a given node and deletes any "displayTextFlow" nodes it encounters. The function is then called on the root node of the XML document to delete the nodes from all levels. Finally, the modified XML is printed out.
