python remove non tags in xml

I want to remove all content, which is not in xml tags (cleanup) and optionally put it in a list. I got some xml like this:

<tag>some text</tag> unwanted text <tag>some text</tag>

and I want to get this with python (regex)

('<tag>some text</tag>','<tag>some text</tag>')

I tried it with:

cleanup = re.findall(r"^<.>.*</.>$",  input)

but I think the whole input matches also the regex how can i fix this ?

Update1:

i try to load it with

import xml.etree.ElementTree as ET
root = ET.fromstring(str(cleanup))
