Xpath: Find element with class that contains spaces

Question

So I have elements that look like this

 # note the space

Answer 1

This XPath 1.0 expression,

//li[contains(concat(' ', normalize-space(@class), ' '),
              ' attribute ')]

will select all li elements with class attributes that contain the attribute substring, regardless of whether it has leading or trailing spaces.

---

If you only want to match attribute with possible leading and trailing spaces only (no other string values), just use normalize-space():

//li[normalize-space(@class) = 'attribute']
