How to read all values of a queue

Hi All,

In Message mapping I am checking condition for field value based on incoming value.

In test cases i can see the second or third  occurence is getting supressed and first value fails the condition and mapping node not created.

I would like to know how to read multiple values from queue and check condition for each value and if correct value present condition should pass.

I tried all possible context changes but no luck.

Any ideas how to read all values coming .

Thanks.
