How to convert XML attributes to text nodes
(3 answers)
Closed 7 years ago.
I want to write a PHP script that will modify my XML file.
I have my productId within the node as an attribute and I want to parse the entire file and convert it to a separate node. So I want to read the attribute of the node and put that attribute in its own node. But the rest of the nodes will stay as is.
Before:
<product id="123">
<name>bob</name>
<lastname>tim</lastname>
</product>
To:
<product>
<id>123</id>
<name>bob</name>
<lastname>tim</lastname>
</product>
Can I do this in PHP? Bearing in mind the file will have over one thousand separate products in it.

Answer 1

You could do it this way.
$xml = new SimpleXMLElement('<product id="123"></product>');
if(!empty($xml['id'])) {
$xml->addChild('id', $xml['id']);
unset($xml['id']);
}
echo $xml->asXML();
Output:
<?xml version="1.0"?>
<product><id>123</id></product>
Here's the manual's link and the addchild functions link. http://php.net/manual/en/class.simplexmlelement.php

Update:
If you had multiple products you could loop like this.
$xml = new SimpleXMLElement('<proudcts><product id="123"></product><product id="234"></product></proudcts>');
foreach($xml as $key => $data){
if(!empty($data['id'])) {
$data->addChild('id', $data['id']);
unset($data['id']);
}
}
echo $xml->asXML();
Output:
<?xml version="1.0"?>
<proudcts><product><id>123</id></product><product><id>234</id></product></proudcts>
