Extract Href Link And Description?
Jul 25, 2009
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 am developing a small software to load an excel file to a website and then create a .kmz file. I have coded up to the file creating point.Now I need some help with the file downloading.The file is something like this "1322559442-10125-61.245.172.28.kmz"And the href value is "/display/1322559442-10125-61.245.172.28.kmz"This is for one file.The next time you upload an excel file to the program you get a different href value.So I want to create a code which can download the first href with the extension

Well I have software which is loading texts from files in folder, also if user wants to click on link he just using "click" button and it will search it for him and will open in built in browser. Thing is that some of those texts has just [URL]
At this moment I'm using this:
For Each link As HtmlElement In webMail.Document.Links
WebBrowser1.Navigate(link.GetAttribute("href"))
Next
BUT I'd like to to be able to click every link with just http in text, no matter if <a href is in use.I guess I can just add <a href to any http string but I guess there must be other way to do that...Should I some how look for any string with http and then just set it as variable and then navigate or can I use other way ???So for now I have 2 ideas, one replace http://... with <a href... a>, or to find any string with http and set it as variable and then navigate to that web browser...

I am working on httpwebrequest method to read the php page from my site. What I am trying to do is to read the php page while read the html tags for each line, find the matched string that I have selected on the listview, then extract and get the full link of the tag called "delete" and then displaying the messagebox. Something would be like this:
[URL]
At the moment, I find it a bit difficult job to work it out on myself to get the right tag as each of them have got the same ids. The id I wish to extract from the page and get the full link is called delete. Something is like this:
<p id="delete"> <a href="delete.php?id=ANYNUMBER1">Delete</a></td><p id="delete"> <a href="delete.php?id=ANYNUMBER2">Delete</a></td>
Here's the php page
Hello
Delete
Whatever the strings goes
Delete
If you know how I can extract each of the tag to get the delete link with the correct id while read the php page and get the matched listview item that I selected.

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'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)?

i am experimenting on a vb app, and i have a text box where you input the value of the href (eg. http://.......) So while the webbrowser is on a webpage which haves many href elements, when i press button1, i want it to find the one we defined at textbox1.text and click the BLUE HREF LINK on the webbrowser (I think this requires javascript)

I have a link here that works perfect for calling the postback close that I need to happen:
<a href="javascript:parent.__doPostBack('Close','')"><asp:Label ID="Label5" runat="server" Text="Close Me"></asp:Label></a>
However, I would like to be able to call the *javascript:parent.__doPostBack('Close','')* method from the code-behind file rather than the user clicking the link. I.e., when I have completed my tasks in the application code, call parent.doPostBack as my last function call, which closes the window in question.

When a button is clicked i am creating HTML that will be displayed in the WebBrowser1 control. With this HTML are several links to other pages. Is it possible that when one of these links is clicked, that WebBrowser2 navigates to the page instead of WebBrowser1?
