Delete Table Column with HTML Agility Pack - c#

I have scraped a table from a website using C# for my own website and loaded it into a string. There are too many columns so I was wondering if there was an easy way to delete some, probably using HTML Agility Pack but in C# if necessary.
The table in the string looks like this:
<table>
<tr>
<th scope="col"> </th>
<th scope="col"> </th>
<th scope="col">P </th>
<th scope="col">W </th>
<th scope="col">L </th>
<th scope="col">T </th>
<th scope="col">NR </th>
<th scope="col">Bat </th>
<th scope="col">Bowl </th>
<th scope="col">Pen </th>
<th scope="col">Pts </th>
</tr>

And I want to delete columns 8-10 (Bat, Bowl and Pen). I'm not really sure where to start so any pointers would be helpful!


You would need to iterate over each tr and remove the 8th, 9th and 10th td nodes from each.
bool first = true;
foreach (HtmlNode row in doc.DocumentNode.SelectNodes("//tr"))
{
if (first)
{
row.RemoveChild(row.SelectSingleNode("th[10]"));
row.RemoveChild(row.SelectSingleNode("th[9]"));
row.RemoveChild(row.SelectSingleNode("th[8]"));
first = false;
}
else
{
row.RemoveChild(row.SelectSingleNode("td[10]"));
row.RemoveChild(row.SelectSingleNode("td[9]"));
row.RemoveChild(row.SelectSingleNode("td[8]"));
}
}

I send the following string to this method, to remove the 3rd and 4th <td> and <th>.
public static string deleteCols(string table)
{
var doc = new HtmlDocument();
doc.LoadHtml(table);
bool first = true;
foreach (HtmlNode row in doc.DocumentNode.SelectNodes("//tr"))
{
if (first)
{
try
{
var th3 = row.SelectSingleNode("th[3]");
row.RemoveChild(th3);
}
catch
{
}
try
{
var th4 = row.SelectSingleNode("th[4]");
row.RemoveChild(th4);
}
catch
{
}
first = false;
}
else
{
try
{
var td3 = row.SelectSingleNode("td[3]");
row.RemoveChild(td3);
}
catch
{
}
try
{
var td4 = row.SelectSingleNode("th[4]");
row.RemoveChild(td4);
}
catch
{
}
}
}
foreach (HtmlNode row2 in doc.DocumentNode.SelectNodes("//span"))
{
row2.Remove();
}
return doc.DocumentNode.InnerHtml;
}
Which gives me the following result:

As you can see, some of the elements I wish to delete are still there. Does anybody know what I'm doing wrong here?!

When you remove the 3rd th/tds from the row's children, the 4th item becomes the 3rd, so you're trying to remove a non-existing element.
As a solution, you can either store the elements in variables at first, and then delete them; or you can start removing from the 4th index.

C# IText7 HTML inside a Table Cell

i try to put HTML in a cell, but the border seems double lines:
cell = new Cell();
var elementsList = HtmlConverter.ConvertToElements(sectioncontent);
foreach (IElement e in elementsList)
{
cell.Add((IBlockElement)e);
}
cell.SetBorder(Border.NO_BORDER);
table.SetTextAlignment(TextAlignment.JUSTIFIED).AddCell(cell);
with html like this (caught from CKEditor and i put in a database):
<table border="1" cellpadding="1" cellspacing="1" style="width:500px">
<tbody>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
</tbody>
</table>
<p> </p>
================================ end
String HTML = "<p>Overview line1</p>"
+ "<p>Overview line2</p><p>Overview line3</p>"
+ "<p>Overview line4</p><p>Overview line4</p>"
+ "<p>Overview line5 </p>";
String CSS = "p { font-family: Cardo; }";
cell = new Cell();
//cell.Add(new Paragraph(s));
ElementList elementsList = XMLWorkerHelper.ParseToElementList(HTML, CSS);
foreach (IElement e in elementsList)
{
cell.Add((IBlockElement)e);
}
cell.SetBorder(Border.NO_BORDER);
table.SetTextAlignment(TextAlignment.JUSTIFIED).AddCell(cell);
document.Add(table);
but it raise exception:
Unable to cast object of type 'iTextSharp.text.Paragraph' to type 'iText.Layout.Element.IElement'.
How to workaround?

And want extract the data nodes.
Most pepole use HtmlAgilityPack and i tried this:
HtmlAgilityPack.HtmlNodeCollection aNodi = doc.DocumentNode.SelectNodes("//table[#id=tabella]/tbody/tr");
Also have tested most parameters in SelectNodes, but return always NULL!
What am i doing wrong?
Thank you all for the help!

If you want to select it by id in SelectNodes you have to wrap tabella in apostrophes:
var aNodi = doc.DocumentNode.SelectNodes("//table[#id='tabella']//tbody//tr");
You could also use GetElementbyId:
var aNodi = doc.GetElementbyId("tabella").SelectNodes("//tbody//tr");

In your javascript you are searching for the div with id widget-content
your code: var divToPrint = document.getElementById('widget-content');
but in your html you have <div class="widget-content"> and it has no id, it only has a class.
So you have 2 options.
OPTION 1
Change class to id
OPTION 2
Change your javascript to search for the class like so
var divToPrint = document.getElementsByClassName('widget-content')
NOTE: this will return an array of elements with that class, whether theres only one or more.
So in order to select the one you want; assuming there is only 1 div with this class you do like so:
var divToPrint = document.getElementsByClassName('widget-content')[0]
