soup.find_all doesnt find regex - regex101 does

Question

I got a html-file and want to change "Test-Dateien" into "other-dir"

since it is nested in some weird outlook vml code i tried using the following regex to access it:

pattern = re.compile(r"\<\!\-\-\[if gte vml 1\]\>\<v\:shape ((.|\n)*?)\-\-\>")

however when regex101 online generator returns match... soup.find_all(text=pattern) returns None

example text copied from soup below:
