XPath: How to select node with some attribute by index?

Question

I have several nodes with some particular attribute and I need to select one of them by index. For example I need to select second <div> with 'test' class - //div[@class='test'][2] doesn't work.

Is there a way to select node with some attribute by index ? How to do it?

Answer 1

This is a FAQ.

In XPath the [] operator has a higher precedence (binds stronger) than the // pseudo-operator.

Because of this, the expression:

//div[@class='test'][2]

selects all div elements whose class attribute is "test" and who (the div elements) are the second such div child of their parent. This is not what you want.

Use:

(//div[@class='test'])[2]
