How Can I Parse XML with Namespaces Using SimpleXML Without Declaring a Prefix?

Parsing XML with Namespace Using SimpleXML

In this scenario, you have an XML document with XML namespaces and you want to parse it using SimpleXML. While the provided example fails, it is possible to achieve the desired result with SimpleXML without declaring a namespace prefix.

Solution:

$xml = new SimpleXMLElement($xmlContent);

foreach ($xml->xpath('//event:event') as $event) {
    var_export($event->xpath('event:sessionKey'));
}

Explanation:

Instead of registering a namespace prefix, you can simply include the full namespace prefix in the XPath expressions. In this case, for the "event" namespace:

• e:event becomes event:event
• e:sessionKey becomes event:sessionKey

Result:

The code will now correctly loop through all the event:event nodes and display the values of the event:sessionKey nodes.
