Question

I’m trying to grab data from an Html table on a website. No XML is involved.

<table id="e-cal-table" class="e-cal-table" width="100%">

<tr>

    <th>Date</th>

    <th>Time</th>

    <th>Currency</th>

    <th>Event</th>

    <th>Importance</th>

    <th>Actual</th>

    <th>Forecast</th>

    <th>Previous</th>

    <th>Notes</th>

</tr>

The following results in “Object reference not set to an instance of an object.”

HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml("http://www.example.com");

string table = doc.DocumentNode.SelectSingleNode("//table[@id='e-cal-table']").InnerText;

I’m at a loss as to how to identify the table for future parsing. Unfortunately, the only examples I’ve been able to find have to do with XML.

Answer 1

Your code works if you load your doc from string.

if you want to load it from an url use doc.Load(url); not doc.LoadHtml(htmlString);

–EDIT–

Sorry, my bad, doc.Load doesn’t accept http
You can use something like this

using (var wc = new WebClient())
{
    doc.LoadHtml(wc.DownloadString(url);
}
