SimpleXmlElement and XPath, getting empty array()

Question

I am having a little trouble with parsing XML from a google checkout response. The XML is coming straight from the google server so there is no problem with the XML itself. I want to get hold of all the new-order-notification tags I tried this but get an empty array() returned everytime. ``` $xml = new SimpleXmlElement($raw_xml); $notifications = $xml->xpath('notifications'); $notifications = $xml->xpath('/notification-history-response/notifications/new-order-notification'); $notifications = $xml->xpath('//new-order-notification'); ``` An XML snipet (Just the beginning) ```

Accepted Answer

The issue is likely the default namespace. See

- `SimpleXMLElement::registerXPathNamespace` Creates a prefix/ns context for the next XPath query

Example:

```
$sxe->registerXPathNamespace('x', 'http://checkout.google.com/schema/2');
$result = $sxe->xpath('//x:notifications');
```

As an alternative if there is no other namespaces, simply remove the default namespace with

```
str_replace('xmlns="http://checkout.google.com/schema/2"', '', $raw_xml);
```

before feeding the XML to your SimpleXmlElement.
