Use IMPORTXML to import from multiple URLs at one time

Question

I have this formula =IMPORTXML(B3;"//h2"), where there is a URL in B3. I want to grab results from at least two URLs at one time, which are in B3 and B4, as I need the results in one column one after another and the number of results is unknown. Neither this:

=IMPORTXML(B3:B4;"//h2")

nor this:

=ArrayFormula(IMPORTXML(B3:B4;"//h2"))

is working.

Is there a way or trick to do that?

Answer 1

Please try:

=query({IMPORTXML(B3;"//h2");IMPORTXML(B4;"//h2")})  

Add further terms inside the curly braces to suit.
