The boolean operator for or is or not | (not sure why so many people miss
this)
[not(name='Frank Lampard' or name=' Damian Deff')]
or
[(name!='Frank Lampard') and (name!=' Damian Deff')]
although beware of using != ever in Xpath unless you are sure you know
what you are doing. It has quite entertaining meaning and in the cases
where it isn't the same as using not ( = ) it almost always doesn't
do what you want, so I find it's better to simply always use not() and
= rather than !=.
Of the things you tried:
[name!='Frank Lampard | Damian Duff']
That is legal and tests that every name element is not equal to teh
string 'Frank Lampard | Damian Duff'
[name!='Frank Lampard' | name!=' Damian Duff']
that is a syntax error as | is set union and can only be applied to node
sets, not to boolean expressions.
