Example 2: Traversing with Iterators
Step 1: Open the transmittal and get the Root Object.
Step 2: Specify SE_Search_Rule for matching <Polygon> objects.
Step 3: Use the Search Rules to create a SE_Search_Filter.
Step 4: Use the Search Filter and Root Object to create a component Iterator.
Step 5: Call SE_GetNextObject() to traverse through matching objects (<Polygons>).
Step 6: … process the <Polygons> ...
Step 7: Free the memory for the object, Search Filter and Iterator.
Step 8: Close the transmittal.
