How to get nodes using xpath

When I have 2 set of nodes with same element name for ex :

<contacts>
    <names>
      ...
    </names>
    <names>
      ...
    </names>
</contacts>

Normally I'd use //contacts/names to get the node, but how do I do if they have the same name how do I get second or first or nth?

For the provided XML document use:

/contacts/names[1]

the above selects the first names element.

/contacts/names[2]

the above selects the second names element.

Try to avoid using the // abbreviation as much as possible, because it is usually grossly inefficient, causes all the (sub)tree roted in the context node to be traversed.

You can do this to get the first and/or second specifically:

//contacts/names[1]
//contacts/names[2]

Use //contacts/names[n] to get the nth names node. For example: //contacts/names[1] gets the first names node while //contacts/names[2] gets the second names node, etc.
