Filter elements by BuiltInParameter using Python

[andrelucashere]

Hey, guys. I'm trying to select some elements where a parameter (comments) == 'something', using BuiltInParameter. 

Condition:

something_a --> comments == 'somethinga' 

something_b --> comments == 'somethingb' 

I've already code a list of elements with some different categories using ElementMultiCategoryFilter:

categories = List[BuiltInCategory]([BuiltInCategory.OST_PipeCurves,
                                    BuiltInCategory.OST_PipeFitting,
                                    BuiltInCategory.OST_PipeAccessory])
custom_filter = ElementMulticategoryFilter(categories)
my_elements = FilteredElementCollector(doc).WherePasses(custom_filter).WhereElementIsNotElementType().ToElements()

Any help would be greatly appreciated!

I've alredy solved it! 😅

categories = List[BuiltInCategory]([BuiltInCategory.OST_PipeCurves,
                                    BuiltInCategory.OST_PipeFitting,
                                    BuiltInCategory.OST_PipeAccessory])
custom_filter = ElementMulticategoryFilter(categories)
my_elements = FilteredElementCollector(doc).WherePasses(custom_filter).WhereElementIsNotElementType().ToElements()

recalque = []

for rec in my_elements:
    if rec.get_Parameter(BuiltInParameter.ALL_MODEL_INSTANCE_COMMENTS).AsString() == 'Recalque':
        recalque.append(rec)
