This is a filter, not a tag. So you just use the filter syntax on a
variable:
{{ tm.element|elementtotext }}
By the way, you might find it easier to use a dictionary to map your
template strings, rather than a whole load of if/else blocks:
mapping = {
'DR': 'door',
(etc)
}
itext = mapping.get(string, 'unknown')
--
DR.
