title: What is the XPath expression to find only the first occurrence?
body: <p>I used this Xpath expression <code>"//span[@class='Big']"</code> and got all elements in that page that are under <code>&lt;span&gt;</code> tag and <code>class='Big'</code>.</p>
  
  <p>My question is what if I want just the first occurrence on the page, not all occurrences, what would be the correct <code>Xpath</code> expression?</p>
  
  <p>Thanks,
  Narin</p>
