A BPEL process invoke a WebService and receive a some kind of response.
Like
<response>
<PersonID>p1-guid</PersonID>
<Error></Error>
</response>
And there are 2 situations i need to check:
1.How to check if <PersonID> element exist in response? (its not a mandatory element)
2.How to check if <PersonID> not null? (when elements exists, but its empty)
Thank you.
