How to get the last table in xpath?

c# html-agility-pack xpath

Question

So I have the following situation:

<table class="table-main detail-odds sortable">
  ..
</table>
<table class="table-main detail-odds sortable">
  ..
</table>

as you can see I have two table with the same classes, I want get the last table (I cannot use index because the number of the table changing).

For the moment I have this code:

HtmlNode oddsTable = doc.DocumentNode
         .SelectNodes("//table[@class='table-main detail-odds sortable']");

unfortunately I cannot find any .Last() method, maybe is possible do this directly with xpath so without use SelectNodes()?

You can use last() as index

"(//table[@class='table-main detail-odds sortable'])[last()]"

Be sure to wrap the expression in parenthesis.

last() will return you the last table only if both tables are children of the same parent. So if HTML really looks like

<table class="table-main detail-odds sortable">
  ..
</table>
<table class="table-main detail-odds sortable">
  ..
</table>

then

//table[@class='table-main detail-odds sortable'][last()]

will fetch required table...

But in case

<div>
    <table class="table-main detail-odds sortable">
  ..
    </table>
</div>
<div>
    <table class="table-main detail-odds sortable">
  ..
    </table>
</div>

you might need

(//table[@class='table-main detail-odds sortable'])[count(//table[@class='table-main detail-odds sortable'])]

From what I can gather, I think its not working because the xpath you're using is expecting the a nodes to be children of your h4 node, I've not tested this, and may be missing interpreting your requirements but......var links = document.DocumentNode.SelectNodes("//h4[contains(text(),'Title')]/following-sibling::*[1]//a"); ...This would get all of ...
