XPath Using 'or'

'or' expression uses two conditions and one of the two conditions must be true to locate a web element. It will fail to locate an element if both the conditions are false.

Following explanation of  'or' expression will help us to understand this topic briefly.

Two conditions with 'or' expression such as A or B returns the result-set shown below:

A	B	Result
False	False	False
True	False	True
False	True	True
True	True	True

Syntax:

//tag[@attribute='value' or @attribute='value']

Example:

//div[@class='form-group' or @id='user-message']

Let's get a clear view with the below example:

When Condition One and Condition Two both are False then no result is found:

//div[@class = 'spch_' or @id = 'spch_']

When Condition One is True and Condition Two is False then result is found:

//div[@class = 'spchc' or @id = 'spch_']

When Condition One is False and Condition Two is True then result is found:

//div[@class = 'spch_' or @id = 'spchc']

When Condition One and Condition Two both are True then result is found:

//div[@class = 'spchc' or @id = 'spchc']
