i want to add the xml node i.e <name>B07BZFZV8D</name> to the XML variable before saving it.
I want to add the 'name' node inside the 'Self' Element.
#Previously i use to save it directly like this,
$Response #this is the respnse from api
$dom = new DOMDocument;
$dom->preserveWhiteSpace = FALSE;
$dom->loadXML($Response);
##saving in file
$myfile = file_put_contents('data.xml', $Response.PHP_EOL , FILE_APPEND | LOCK_EX);
With DOM you use methods of the document object to create the node and methods of the parent node to insert/add it to the hierarchy.
DOMDocument has create* methods for the different node types (element, text, cdata section, comment, ...). The parent nodes (element, document, fragment) have methods like appendChild and insertBefore to add/remove them.
Xpath can be used to fetch nodes from the DOM.
$document = new DOMDocument;
$document->preserveWhiteSpace = FALSE;
$document->loadXML($xmlString);
$xpath = new DOMXpath($document);
// fetch the first Data element inside the Report document element
foreach ($xpath->evaluate('/Report/Data[1]') as $data) {
// create the name element and append it
$name = $data->appendChild($document->createElement('name'));
// create a node for the text content and append it
$name->appendChild($document->createTextNode('Vivian'));
}
$document->formatOutput = TRUE;
echo $document->saveXML();
Output:
<?xml version="1.0" encoding="UTF-8"?>
<Report>
<Data>
<id>87236</id>
<purchase>3</purchase>
<address>XXXXXXXX</address>
<name>Vivian</name>
</Data>
</Report>
Using @ThW Code: Need to change Create Element functionality
$document = new DOMDocument;
$document->preserveWhiteSpace = FALSE;
$document->loadXML($xmlString);
$xpath = new DOMXpath($document);
// fetch the first Data element inside the Report document element
foreach ($xpath->evaluate('/Report/Data[1]') as $data) {
// create the name element with value and append it
$xmlElement = $document->createElement('name', 'Vivian');
$data->appendChild($xmlElement);
}
$document->formatOutput = TRUE;
echo $document->saveXML();
It works for me with php7.0. Check it works for you.
