I have used .NET and ShDocVw for years to grab data off webpages without any issues I couldn't overcome. This website has me beat though. It seems like such as easy task to grab the titles and other information off a library search page, but I can't see the data to be able to grab it. Usually, I just look in the DOM, but the data wasn't there. I did a view source, but the data wasn't there.

I'm building a vb project using vb 2008 and I am trying to get a specific data from the source of a webpage. I am now trying to have the vb project access the below source of the webpage [URL] and retrieve the word "Dublin" from the code from the following line:
</tr><tr><td class="s7 li ou"><a href="dorf1.php?newdid=106467">Dublin</a></td>
The word "Dublin" should be stored in the string villagename1 (I will use that string several times later in the project) and it should at NO time open a IE page as to make it as invisible as possible.
Webpage Source:

View 1 RepliesI was wonder how, if you can, can I create a WebBrowser control or something similar to this, that will contain a selected area of information, and that information only. So it doesn't load and show the whole web page, only the part I choose.

How can I get a specific area of a webpage, loaded into a form, that is able to be reloaded/refreshed later on?
I've search numerous hours, but I haven't been able to find the appropriate solution. What I want to do: Get the html of a certain webpage (Lets say in this case url...this html within my wpf application, so that you can see the content of the page you requested. Then I want to be able to trigger events on the html that has been loaded from the URL. Like I want you to be able to click on a certain node in the HTML and I want to be able to link this node to a certain value. Basically a crawler application that let's you request a page, see the page in a control and allows you to click in the loaded HTML and link values to predefined values you set. So basically I want to be able to get a webpage displayed within my application and be able to trigger events on the html (For example a click on the html which would need me to know on what node you clicked in the html, or for example be able to edit the html by clicking in it).
