Next Page without Next link

Sometimes web sites puts a list of page numbers in a search result instead of a easy clickable Next button.

One technique would be if we can referrer to the active list element and by finding the first sibling after that. An example:

<ul id="ul">
  <li class="selected">1<li>
  <li><a href>2</a><li>
  <li><a href>3</a><li>
  <li><a href>4</a><li>
</ul>

An xpath expression to get next page element would be:

id(“ul”)/li[class=”selected”]/following-sibling::li[1]/a
