Let's say I have this XML file.
<book>
<id>1</id>
<title>Harry Potter - bla bla bla</title>
<author>J.K Rowling</author>
</book>
<book>
<id>2</id>
<title>Other book</title>
<author>A Name</author>
</book>
Is there a way where I can read via PHP and get the #2 id, or do I have to use an IF?
Like jQuery selector ':eq(2)', or MySql 'WHERE id
=2'
