you need all the website text or specific text ?

Fail4FunTV 7-Oct-14 8:27am

specific text from id "quick-details"

What does it mean 'doesn't work'?
How did you loaded the page?
Are you aware that 'quick-details' is a <dl> element and has no value attribute?

try this :

System.IO.StreamReader reader;
 WebRequest request = WebRequest.Create("http://www.macvendorlookup.com/");
 request.Timeout = 120000;
 WebResponse response = request.GetResponse();
 reader = new System.IO.StreamReader(response.GetResponseStream());
 string get = reader.ReadToEnd();
MatchCollection m1 = Regex.Matches(get, @"(<dl class="dl-horizontal" id="quick-details">)(.*?)(</dl>)", RegexOptions.Singleline);
foreach (Match m in m1)
 {
string cell = m.Groups[1].Value;
}

I attached it like this:

private void button3_Click(object sender, EventArgs e)
{
System.IO.StreamReader reader;
WebRequest request = WebRequest.Create("http://www.macvendorlookup.com/");
request.Timeout = 120000;
WebResponse response = request.GetResponse();
reader = new System.IO.StreamReader(response.GetResponseStream());
string get = reader.ReadToEnd();
MatchCollection m1 = Regex.Matches(get, @"(<dl class=""dl-horizontal"" id=""quick-details"">)(.*?)(</dl>)", RegexOptions.Singleline);
foreach (Match m in m1)
{
string cell = m.Groups[1].Value;
}
}

But where am i supposed to see the text?

[no name] 7-Oct-14 9:05am

replace string cell = m.Groups[1].Value; by string cell = m.Groups[0].Value;
and change
MatchCollection m1 = Regex.Matches(get, @"(<dl class=""dl-horizontal"" id=""quick-details"">)(.*?)(</dl>)", RegexOptions.Singleline);
to
MatchCollection m1 = Regex.Matches(get, @"(quick-details)(.*?)(</dl>)", RegexOptions.Singleline);
then in the string cell you will have the text between quick-details and </dl>

And to get the text i want into a textbox i do:

textBox7.Text = m1.ToString(); ?

System.IO.StreamReader reader;
WebRequest request = WebRequest.Create("http://www.macvendorlookup.com/");
request.Timeout = 120000;
WebResponse response = request.GetResponse();
reader = new System.IO.StreamReader(response.GetResponseStream());
string get = reader.ReadToEnd();
MatchCollection m1 = Regex.Matches(get, @"(quick-details)(.*?)(</dl>)", RegexOptions.Singleline);
foreach (Match m in m1)
{
string cell = m.Groups[0].Value;
}
textBox7.Text = cell;

[no name] 7-Oct-14 9:12am

string cell="";
System.IO.StreamReader reader;
WebRequest request = WebRequest.Create("http://www.macvendorlookup.com/");
request.Timeout = 120000;
WebResponse response = request.GetResponse();
reader = new System.IO.StreamReader(response.GetResponseStream());
string get = reader.ReadToEnd();
MatchCollection m1 = Regex.Matches(get, @"(quick-details)(.*?)(</dl>)", RegexOptions.Singleline);
foreach (Match m in m1)
{
cell = m.Groups[0].Value;
}
textBox7.Text = cell;

That gave me all this:

quick-details">

<dt>Company</dt>
<dd>

</dd>

<dt>Address</dt>
<dd>

</dd>

<dt>Range</dt>
<dd>
<div id="hex">
 - 
</div>
</dd>

<dt>Type</dt>
<dd>IEEE </dd>
</dl>

it give you the text between what you have put on
MatchCollection m1 = Regex.Matches(get, @"(quick-details)(.*?)(</dl>)", RegexOptions.Singleline);
mean between quick-details and </dl> what you need exactly ?

I am making an application like this:

1. I type in MAC Adress
2. I will get Vendor "name" on a label/textbox.

[no name] 7-Oct-14 9:26am

mean check this link :
http://www.macvendorlookup.com/mac-address-api

and call this :
http://www.macvendorlookup.com/api/v2/{MAC_Address}
or

[no name] 7-Oct-14 9:26am

this is a test one :
string cell="";
System.IO.StreamReader reader;
WebRequest request = WebRequest.Create("http://www.macvendorlookup.com/api/v2/{00:11:22:33:aa:bb}");
request.Timeout = 120000;
WebResponse response = request.GetResponse();
reader = new System.IO.StreamReader(response.GetResponseStream());
string get = reader.ReadToEnd();
MatchCollection m1 = Regex.Matches(get, @"(company)(.*?)(}])", RegexOptions.Singleline);
foreach (Match m in m1)
{
cell = m.Groups[0].Value;
}
textBox7.Text = cell.Trim();

Yes, i tried with this MAC: 38:E7:D8:10:A0:23

It worked, but a bit messy:

company":"HTC Corporation","addressL1":"No.23 Xinghua Road","addressL2":"Taoyuan City","addressL3":"Taoyuan County 330","country":"TAIWAN, PROVINCE OF CHINA","type":"MA-L"}]

[no name] 7-Oct-14 9:38am
