title: XML Xpath - select where element = multiple values
body: <p>Fairly straightforward question, but seems pretty hard to find what I want through search, here or Google.</p>
  
  <p>Most people ask how you can select a node/ element with multiple conditions.</p>
  
  <p>Like <code>URL/books[title="Harry Potter" and author="JKRowling"]</code></p>
  
  <p>I want to know if there's a way to shorten that syntax if you have multiple possibilities for one attribute.</p>
  
  <p>In other words</p>
  
  <pre><code>URL/books[price=1 or price=2 or price=3 or price=8 or price=15]
  </code></pre>
  
  <p>Is there a way to shorten that syntax?</p>
  
  <p>Like <code>URL/books[price=1,2,3]</code> or <code>[price in (1,2,3)]</code> ---- obviously these are wrong, but would make things easier.</p>
