:::>trace (pxml) // returns [object Object] as expected
:::>trace (pxml.moduleExam.question[0].ID) // returns undefined
:::>trace (pxml.moduleExam.question[1].ID) // returns undefined
:::>trace (pxml.moduleExam.question[0].statement) // returns 0.
:::>Identify the...
:::>as expected
:::>trace (pxml.moduleExam.question[1].statement) // returns 1. It is
