How to select the first element with a specific attribute using XPath

Question

The XPath `bookstore/book[1]` selects the first book node under `bookstore`. How can I select the first node that matches a more complicated condition, e.g. the first node that matches `/bookstore/book[@location='US']`

Accepted Answer

Use:

```
(/bookstore/book[@location='US'])[1]
```

This will first get the book elements with the location attribute equal to 'US'. Then it will select the first node from that set. Note the use of parentheses, which are required by some implementations.

Note, this is not the same as `/bookstore/book[1][@location='US']` unless the first element also happens to have that location attribute.
