Select multiple elements with XPath

Question

I have seen a few similar questions on this but can't seem to find a solution. According to the XPath syntax here:
https://www.w3schools.com/xml/xpath_syntax.asp
An expression like this should match all buttons with name="action_rfq_send":
//button[@name='action_rfq_send']
However, the Odoo documentation for view inheritance says that the first node found from an xpath expression is the one selected:
http://www.odoo.com/documentation/10.0/reference/views.html#inheritance
Does this mean there is

You cannot select all with a single xpath expression. You have to select one by one if more than one button with same name needs to referenced. Like:

I don't know how to do it with one expression, but you can do this:
<xpath expr="//form/group[1]" ...
<xpath expr="//form/group[2]" ...
<xpath expr="//form/group[3]" ...

In my case using numbers fails. Just repeat the same expression as many times as you need:

You need to use parentheses around the xpath expression and from there use the index.

expr = "(//button[@name='action_rfq_send'])[1]"
expr = "(//button[@name='action_rfq_send'])[2]"
expr = "(//button[@name='action_rfq_send'])[3]"
