After executing these instructions:
elementRef:=DOM Find XML element($root;"myElement")
DOM GET XML CHILD NODES(elementRef;$typeArr;$textArr)
... the $typeArr and $textArr arrays will contain the following values:
| $typeArr{1}=6 | $textArr{1} = "Hello" |
|---|---|
| $typeArr{2}=11 | $textArr{2} = "AEF1233456878977" (element reference ) |
| $typeArr{3}=6 | $textArr{3} = "New" |
| $typeArr{4}=11 | $textArr{4} = "AEF1237897734568" (element reference ) |
