Get Parameter Value by Name 
Get value of one of element's parameters.

#Imports.
from Autodesk.Revit.DB import Element

doc = __revit__.ActiveUIDocument.Document
uidoc = __revit__.ActiveUIDocument

def get_parameter_value_by_name(element, parameterName):
    return element.LookupParameter(parameterName).AsValueString()

#Select elements from revit.
selection = [doc.GetElement(x) for x in uidoc.Selection.GetElementIds()]

#Example with Walls.
for wall in selection:
    print get_parameter_value_by_name(wall, "Base Constraint")

But there I only get "Base Constraint" is it possible to get all Elements/Categories into that file?

Thanks a lot. Best regards

You can use rpw Collector to get all FamilySymbol elements. If you only want all instances in your project. Just use 'FamilyInstance' to get them.

from rpw import db

collector = db.Collector(of_class='FamilySymbol')
elements = collector.get_elements()

for e in elements:
    print(e.name)
