If a tag contains children, how can I change the text of the tag without
changing or destroying the children?

e.g., in a case like:

<*tag1*> foo <*tag2*> abcdef <*tag3*> ghijkl </*tag3*></*tag2*></*tag1*>

how can I change "foo" to "bar" without changing anything else?

I cannot simply do:
     tag1.string = "bar"
because, according to the BS4 documentation "Be careful: if the tag
contained other tags, they and all their contents will be destroyed."

Just replace the first node with the desired text:

tag.contents[0].replaceWith("new string")

Add in checks for an empty tag.contents if necessary.
