With HTML Agility Pack, you can parse tables in HTML documents and extract TRs and TDs.

html-agility-pack html-parsing vb.net


I assigned a task to change the format of old data in table form.

Old fake data looks like this:

<td>Some text 1.</td>
<td>Some text 2.</td>
..... //any number of TRs goes here

The issue arises because the new data must be in this format:

Several texts: 1. Several texts: 2.

Summary of what must be done in this case:

The table contains all TRs. Find the first TD for each TR, then join it to the second TD by placing a "-" between them.

I'm using VB.Net with HTML Agility Pack.

Please Offer Your Assistance.

Regards and thanks.

To obtain all tds from the table node, retrieve all the InnerText of these nodes, and construct a new TR or TD, you may use Linq and HTML Agility Pack.

// tableNode is the <table> HtmlNode. If you know where is this table you can use XPath to find him.

Dim sb As New StringBuilder()
For Each childNode As HtmlNode In tableNode.DescendantNodes().Where(Function(n) n.Name = "td")
    sb.Append(String.Format("{0} - ", childNode.InnerText))


Dim newTrNode As HtmlNode = tableNode.OwnerDocument.CreateElement("tr")
Dim newTdNode As HtmlNode = tableNode.OwnerDocument.CreateElement("td")

newTdNode.InnerHtml = sb.ToString()


Hope it's useful.
