Review comment:
`getElementText()` internally creates a `new StringBuilder()` per every
call and appends text (`getText()`) of a given element. Attempt to use non-text
elements would throw various exceptions. I have check multiple implementations
of this method, and it seems concrete classes are null-safe.
