Well, string() isn't an axis that you can walk down, and Jaxen doesn't accept it.
Maybe you are thinking of text() - if we were dealing with elements and not attributes
you could do:
/A/B/text()
to get a list of String objects containing all text nodes under /A/B, but the original
expression was /A/@B so that doesn't help.
IMHO writing an extension function for this is overkill since it is easy to do with
dom4j.

So, we don't think this would work, really?
/A/B/string(.)
Select all A nodes.
Select all B children of those A nodes.
For each B node, select the string value of it.
Granted, I haven't tested this...
