how to append list of DOM elements objects to another list of DOM element objects

Question

I have listed some DOM elements from a XML file and kept in list1.

list1 = [<DOM Element: DeviceInfo at 0x1915c88>, <DOM Element: ManagementServer at 0x1961b70>, <DOM Element: GatewayInfo at 0x19cd5d0>]

I have another list2, which also has DOM elements objects,

list2 = [<DOM Element: VendorConfigFile__INSTANCE__ at 0x1915f08>, <DOM Element: SupportedDataModel__INSTANCE__ at 0x191bda0>]

i want to append the list2 to list1. I use the command.

newList = list1.append(list2)

expected output:

newList = [<DOM Element: DeviceInfo at 0x1915c88>, <DOM Element: ManagementServer at 0x1961b70>, <DOM Element: GatewayInfo at 0x19cd5d0>,[<DOM Element: VendorConfigFile__INSTANCE__ at 0x1915f08>, <DOM Element: SupportedDataModel__INSTANCE__ at 0x191bda0>]]

but I'm getting it as 'None' in the newList

what exactly is the problem and how to get this done.

Thank you

in my lists it contains <'DOM Element:SupportedDataModel__INSTANCE__ at 0x191bda0'> and many such DOM element objects, contents inside <> are not displayed inside the list.

Updated!

return type of append is None. so list1.append(list2) gives out None but also changes list1. so you should do.

newList = list(list1)
newList.append(list(list2))

hi Dinesh, i want it exactly like lists of lists: my new list should look like, newList = [ list1 , [list2] ] – Sharath K Nov 26 '14 at 06:01
If your `list1` and `list2` doesn't contain lists with in them, you can use this. else use `deepcopy()` instead of `list()` – Dinesh Panchananam Nov 26 '14 at 06:25
