PHP Domdocument use saveXML instead of save

Question

I am creating an XML file in PHP like this...

$myXML = new DOMDocument();
$myXML ->formatOutput = true;
$data = $myXML ->createElement('data');
$data->nodeValue = 'mydata';
$final->appendChild($data);
$myXML ->save('/mypath/myfile.xml');

This works, but how can I convert this to use saveXML() instead? I have tried like this but I get nothing

$myXML->saveXML();

Where am I going wrong?

• Jason K: saveXML() returns a string you need to echo it or assign a variable.

Answer 1

I see two things:

• $final is not declared. Change it.
• In case saveXML() is called, the output has to be assigned to a variable or printed

Here goes the working code:

<?php
$myXML = new DOMDocument();
$myXML ->formatOutput = true;
$data = $myXML ->createElement('data');
$data->nodeValue = 'mydata';
$myXML->appendChild($data);
echo $myXML ->saveXML();
?>

Output:

<?xml version="1.0"?>
<data>mydata</data>
