Xpath Node to String

Programmer Question

How can I select the string contents of the following nodes:

 word
 test



 word
 test2
 more words

I have tried a few things

//span/text()

Doesn't get the bold tag

//span/string(.)

is invalid

string(//span)

only selects 1 node

I am using simple_xml in php and the only other option I think is to use //span which returns:

Array
(
    [0] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [class] => url
                )

            [b] => test
        )

    [1] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [class] => url
                )

            [b] => test2
        )

)

*note that it is also dropping the "more words" text from the second span.

So I guess I could then flatten the item in the array using php some how? Xpath is preferred, but any other ideas would help too.
