BPEL implement while-continue logic

Question

Greetings,
In java, one could use the continue statement to skip current iteration within a while, for or do-while loop.
Is it possible to implement similar flow control in BPEL within in a while activity?
Thanks.

Answer 1

Sure, in my case, I have a variable list of elements that I am dealing within the while loop activity.
E.G. I have an array of addresses. In the while loop, for each address, I want to execute some logic only if the address is valid. I check if the address is valid first thing inside the loop. If the address is invalid, then I want to skip current iteration and proceed with rest of the elements.
Alternatively, I could iterate over the array first, pick only valid address assign it to a temp array and then reiterate again on all valid addresses in the temp array. This will involve iterating over the array elements twice, which I was tying to avoid.
It would be nice to have a "continue" statement in BPEL!
Thanks.
