I have the following code to open a webpage:
Dim IE As Object
Dim x As Integer
Dim c As Variant
[code]....
The page that opens is in xml and in that xml there is the "page_count" that I need to pick out so I can tell my macro when to stop looping. I have dimmed it as "c" in the code above. Following is the XML.
<search>
<total_items>360</total_items>
<page_size>100</page_size>
<page_count>4</page_count>
Somehow I need c = "4", which is the "page_count". Does anyone know how I can pick out the "4" from the xml on my page?

I have a login form and what it does its uses datastream or webrequest and post's a url to a php file i have. If the login is true, it will return a 1, if it is a bad login, it will return 0. But my problem is that the acars wont read 1 or 0. it reads all of the html on the page. Is there anyway i can make it so it only displays a 1 or 0 to the acars, and not all the html of the page?

Basically I am building a webcrawler and in order to do so
I have to extract the page source of a webpage which I can do so like this:
CODE:
The above code works fine on most of the websites I have tried to extract page source from but for some reason it is failing to extract the html contents of few websites like these where the message posted by a user is nowhere to be seen? The webpage in question is this: [URL]
Is there something I have missed or is it due to forum protection etc which is preventing the vb application from extracting the whole page source?

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).

Private Sub AlertStringDownloaded(ByVal sender As Object, ByVal e As DownloadStringCompletedEventArgs)
If e.Cancelled = False AndAlso e.Error Is Nothing Then
