PHP SimpleXMLElement problems with xml node

I want to create an XML with the following structure:

<?xml version="1.0" encoding="UTF-8"?>
<content>
    <!-- content goes here -->
</content>

I originally created the xml node like this:

$xml = new SimpleXMLElement('<xml/>');
$content = $xml->addChild('content');
// add data to content

but that doesn't allow for adding attributes to the xml node, so now I do this:

$xml = new SimpleXMLElement('<?xml version="1.0" encoding="UTF-8"?>'
                      .'<content></content>');

For some reason it doesn't work without adding the content node, but whatever, it gets the structure right.

Now, how do I assign the content node to a variable like I did above, so I can add data to it?

An XML document must have at least one element. That is the document element. In your question this is the content element.

You can create a SimpleXMLElement of it by just instantiating it with this minimum string:

$xml = new SimpleXMLElement('<content/>');

The variable $xml then represents that element. You can then...

  • ... add attributes: $xml['attribute'] = 'value';
  • ... set the content-text: $xml[0] = 'text';
  • ... add child-elements: $xml->child = 'value';

This exemplary line-up then would have created the following XML (beautified, also: online demo):

<?xml version="1.0"?>
<content attribute="value">
  text
  <child>value</child>
</content>

In your case the $xml variable is equal to the content node just try the following:

$xml = new SimpleXMLElement('<?xml version="1.0" encoding="UTF-8"?>'
    .'<content></content>');
$xml->addAttribute('Attribute', 'value');
$xml->addChild('node_name', 'value');
echo $xml->asXML();

this should print

<?xml version="1.0" encoding="UTF-8"?>
<content Attribute="value"><node_name>value</node_name></content>

E.g.

<?php
$content = new SimpleXMLElement('<content />');
$content['attr']='value';

echo $content->asXML();

prints

<?xml version="1.0"?>
<content attr="value"/>

--- edit:
To keep the encoding=utf-8:

$content = new SimpleXMLElement('<?xml version="1.0" encoding="UTF-8"?>
<content />');
