Question

I’m trying to extract the content inside div tag with id job_title1 in a html page. I’m using htmlagilitypack to fetch the data. Here is my code

        var obj = new HtmlWeb();
        var document = obj.Load("url of website ");

        var bold = document.DocumentNode.SelectNodes("//div[@class='job_title1']");

        foreach (var i in document.DocumentNode.SelectNodes("//div[@class='job_title1']"))
        {
            Response.Write(i.InnerHtml);
        }

When i tried to run this code i’m getting error at foreach saying the Object reference not set to an instance of an object. Please help me solving this.

Answer 1

check if null like this:

var nodes = document.DocumentNode.SelectNodes("//div[@class='job_title1']");

if(nodes != null)
    foreach (var i in document.DocumentNode.SelectNodes("//div[@class='job_title1']"
    ...

Edit: Use \" instead ':

var obj = new HtmlWeb();
var document = obj.Load("url of website ");

var bold = document.DocumentNode.SelectNodes("//div[@class=\"job_title1\"]");

if(bold!= null)
    foreach (var i in bold)
    {
        Response.Write(i.InnerHtml);
    }
