I have the following Crawler.cs helper class:
_using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Linq;
namespace CrawlerWeb
{
The following partial main class:
_private void btnCrawl_Click(object sender, EventArgs e)
<B>Name : </B> WILLIAMS AJAYA L <BR>
<B>Address : </B> NEW YORK NY <BR>
<B>Profession : </B> ATHLETIC TRAINER <BR>
<B>License No: </B> 001475 <BR>
<B>Date of Licensure : </B> 01/12/07 <BR> <B>Additional Qualification : </B> Not applicable in this profession <BR>
<B> <A href="http://www.op.nysed.gov/help.htm#status"> Status :</A></B> REGISTERED <BR>
<B>Registered through last day of : </B> 08/15 <BR>
