2

Answer 1

According to this answer, which explains why it is important to make sure substrings of the class name that one is looking for are not included, the correct answer should be:

//div[contains(concat(' ', normalize-space(@class), ' '), ' class1 ')
    and contains(concat(' ', normalize-space(@class), ' '), ' class2 ')]
