To select elements of a specific position the position() function can be used with a predicate:
<!-- select all product detail urls -->
<html>
<div>
<h2>Product 1</h2>
<a href="/product/1/reviews">reviews</a>
<a href="/product/1/details">details</a>
<a href="/product/1/refunds">refunds</a>
</div>
<div>
<h2>Product 2</h2>
<a href="/product/2/reviews">reviews</a>
<a href="/product/2/details">details</a>
<a href="/product/2/refunds">refunds</a>
</div>
</html>
Note that using position() when web scraping is not recommended as HTML element position is likely to change. Instead other methods like selection by attribute value is a more reliable way if applicable.
