I'm trying to scrape the right url from html file using webbrowser I want to scrape this Href and navigate to it. But the problem is every other comment with reply is almost the same. So if I use to scrape hrefs and check the name it will give me the reply buttons of all the comments + the new comment button. Is there a way to grab this link only this one by it's Class name or something?

<a href="forums.php?op=post&p=1409971">Reply To This</a> I'm trying to create my own browser and this should be a button short cut If I want to comment.

I'm trying to make an app that will scrape numbers off of a webpage. What I want to do is have it read the Game Name and then Views (for statistics keeping). The WebPage is set up like
<tr class="odd">
here are 7 <td> tags that display different things
</tr>
[Code]....
I'd like the app to check the second TD tag to see if it's innertext says, lets say, 'GAME', and then if it does, it adds the innertext of the 7th TD tag (which is a number), to the total sum, and it scrapes all of that info off the page.
I can understand the logic of how to process the info, but I have no clue as to reading the correct tags.

I'm just starting working on a program and the amount of pages I'm trying to screen scrape take over 20 minutes, so I was hoping I could run like 4 or 5 threads to cut that down??? I'm pretty much still a novice, so be easy on me. I understand good, though.

I am *VERY* new to web-scraping and am trying to scrape some information off of a webpage that is heavily javascript enabled. An example of the page I am trying to scrape from is: [URL] I am trying to scrape the property links such as "322 E 98th St" The text appears on the webpage and I can find the link myself, but it doesn't appear in the page source code.
I am trying to scrape it using the webbrowser control using the WebBrowser1.DocumentText property, but it doesn't even show the links simply when I view the source in ie. I am sure this has something to do with the javascript it uses to load up the page or maybe iFrames,

Ok so basically heres what i need to do: Extract text from the webpage that meets a certain criteria. There will be a ton of these on 1 page and i would like to add them to a rich textbox on sperate lines.
I know that it needs to be in a loop and its needs to Parse the wepage(Dim web1 As String = Me.WebBrowser1.Document.Body.InnerText)
The criteria is: Starts with 1 to 4(random) integers, Followed by "my" then 13(random) numbers and letters. Or if it starts with "167my" + 6(random) number and letters.
Edit: Also im going to try to make it loop through a list of webpages to do this.

Should be simple, but can't figure out how to do it.
Want:
<a href="/sites/folder/page.aspx?variable=123456">Test</a>
By:
<a href="/sites/folder/page.aspx?variable=<% Request.QueryString("variable1") %>">Test</a>
I've tried <%# and <%= not expecting either of them to work, but trying them out.

I need to find several hrefs in html like this:
<table>
<tr><td><a href="url1">link1</a></td>
<td><a href="url2"><img src="image.jpg" /></a></td>
</tr>
</table>
Once found I need to add (replace) to each href something like this:
?ID=1
therefore the html should turn out like this:
<table>
<tr><td><a href="url1?ID=1">link1</a></td>
<td><a href="url2?ID=1"><img src="image.jpg" /></a></td>
</tr>
</table>

Ive just started vb.net programming, and Im trying to make an application to collect twitter usernames and addresses - this is how all the links look:
<a target="_blank" href="http:twitter.com/USERNAME" class="twtr-user">USERNAME</a>
So in the tag of <a>, for each element, there is a class called "twtr-user" So basically, is there a way to go through the webpage and add each username and address to a listbox? This is what Ive come up with so far:
For Each temp As HtmlElement In wb.document.Links
Dim str As String
str = temp.GetAttribute("class")
[code]....
The problem is that (1) this doesnt work at all (2) Is there a way to add the href address and also the outer text?

I'm a beginner level developer and I'm having some trouble in extracting the the link description out of a string that contains a html webpage.
Code:
Dim r As Regex
Dim m As Match
r = New Regex("hrefs*=s*(?:""(?<1>[^""]*)""|(?<1>S+))", RegexOptions.IgnoreCase Or RegexOptions.Compiled)
m = r.Match(sInputstring)
[Code]...
This code gives me all the links in the string and puts them in the listbox but how do I go about retrieving the description for it? (the text between the <a href=" "> and </a> )

The following does not work as the syntax is incorrect - the speech marks are required to specify the link, however at the same time they terminate the speech marks containing the value of RegisteredStatus.InnerHtml.
How should I be writing this?
RegisteredStatus.InnerHtml = "<p>To save favorites and create your own user profile space, please click <a href="../Register.aspx"><u>here</u>.</a></p>"

I'll start off by saying my website has a landing page of http:[url]....
On PageOne.aspx, I have a link to another page: http:[url].....
On PageTwo.aspx, I have an link to the following:
<a href="http:[url].....
The /MyFiles/ directory is actually a virtual directory which points to a file server that holds many other files (PDF, jpeg, doc, etc.).When I navigate to PageTwo.aspx from PageOne.aspx, I can click "back" and still get to PageOne.aspx (my browser history is ok). When I click on the link on PageTwo.aspx, the PDF opens in the same window...then I can click "back" to get back to PageTwo.aspx, but I can't click "back" again to get to PageOne.aspx (it seems like my browser history has been reduced by one page).
I can only imagine that this happens because of the virtual directory since I can't duplicate this problem if the PDF resides on the same server as my .aspx pages. If that is the case, does anyone know how to get around this and still have my PDF reside on the file server (virtual directory)?
