Extract an element from XML

Hi all,

I have the following segment of XML:

165432

Now I want to get the value of the BookingReference where the
ReferenceSource = "api". In other words I want to get the value 165432.

I have the following code:

$ItemConfirmationReference2 = $xpath->query('BookingReference
ReferenceSource' , $Element);

$ItemConfirmationReference =
trim($ItemConfirmationReference2->item(0)->textContent);

The $Element variable passes the node that contains the BookingReference
node.

The tricky part for me is the ="api" part.

Thanks in advance.

A

Hi Angelo,

Probably it is something along the lines like:

$xpath->query('BookingReference/[@ReferenceSource="api"]/');

Fairly simple and XPath is way powerful!

Ah, sorry about that:

$xpath->query('BookingReference[@ReferenceSource="api"]/');

There was a '/' after BookingReference.....
