I am not clear how to express my problem correctly in the question so forgive me if I am not able to properly convey my problem. I have following data.
<tr class="header">Random Value 1</tr>
<tr class="item">1</tr>
<tr class="item">2</tr>
<tr class="item">3</tr>
<tr class="header">Random Value 2</tr>
<tr class="item">4</tr>
<tr class="item">5</tr>
<tr class="item">6</tr>
<tr class="header">Random Value 3</tr>
<tr class="item">7</tr>
<tr class="item">8</tr>
<tr class="item">9</tr>
What I want to acheive is that I want to select the with class header. I have achieved this by using the following line of code,
HtmlNodeCollection headerNodes = doc.DocumentNode.SelectNodes("//tr[@class='header']");
Now I have all the header rows in the collection. Now I loop through all the header nodes and I want to get the table rows which are adjacent to the respective header rows.
foreach (HtmlNode node in headerNodes)
{
HtmlNodeCollection itemNodes = ???
}
My question is that what I should write here so that for header row with text "Random Value 1" I get the item rows 1,2 and 3. Similarly for header row with text "Random Value 2" I get the item row 4,5 and 6 and so on.
