xpath return all non-blank text nodes not descendant of `a`, `style` or `script`

Question

What expression would select all text nodes which are:

• not blank
• not inside a, or script o

Answer 1

This should do, assuming "not inside" means the text node is not supposed to be a descendant of an "a" or "script" or "style" element. If "not inside" only means not supposed to be a child then use parent::a and so on instead of ancestor::a.

//text()[normalize-space() and not(ancestor::a | ancestor::script | ancestor::style)]
