I need to find .MP3 format URLS in a HTML source code.So how could i do that?Lets say i have:
Dim wcClient As New System.Net.WebClient
Dim data As System.IO.Stream = wcClient.OpenRead(inbox.ToString)
Dim reader As System.IO.StreamReader = New System.IO.StreamReader(data)
reader = reader.ReadToEnd()
reader.Close()
so how could i find all the .MP3 urls which are in the source code?
I've found some examples using RegEx but im not really sure how to use the RegEx pattern to find MP3 urls in the source code.
i can parse html source code and regex a few things, but i know the exact phrase i'm looking for do i still need a regex if i know what i'm looking for?
if (string = logged) then
do the code if 'logged' is found in the html source
else

i am trying to find the param for a shockwave video within the web page source. The source looks like this:
[Code]....
This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.
What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.
Here is the source that I am getting using Firefox's Firebug to inspect the element:
<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>
[Code]...
Why would the two be showing me two different versions of the HTML?
And how would you be able to grab that source to view in a picturebox using webclient?
I'm working on a program that gets some info about a certain web page. But one of the features is it needs to find all the links to other webpages on THE SAME site (I think its called an internal link... not sure). I already figured out how to get the page's HTML code, now i just need to know how to find stuff like "" in the HTML code then output me [URL]
View 4 RepliesWay to space out the source code of a web page, having each tag on one line, without having to search for each tag ending and then making a new line after.
My code for obtaining the source code is:

Also if anyone knows a way to colour the tags.
I am trying save a value from an input tag in some HTML source code. The tag looks like so:
<input name="user_status" value="3" />
I have the page source in a variable (pageSourceCode), and need to work out some regex to get the value (3 in this example). I have this so far: [Code] Which works fine most of the time, however this code is used to process source code from multiple sites (that use the same platform), and sometimes there are other attributes included in the input tag, or they are in a different order, eg:
<input class="someclass" type="hidden" value="3" name="user_status" />
I just dont understand regex enough to cope with these situations.

I certain html page contains links that are displayed with each onclick event. I am unable to parse the html for the url that will follow these onlick links. If this is the source on the page, how do I capture the content that each onclick link displays. In other words for example:

Now this is the onclick link that will display some content which I need to capture. Basically I want to be able to activate the onclick event from a program to display and capture the url links from that specific page.
I've been programming in VB.NET 2005, 2008 and now 2010 for almost 2 years. Just casual little applications, nothing big.In this project I need to parse links from a web page, it doesn't quite work though, it parses the names only and no links.I'll give you my code, let's say for a random page:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
TextBox1.Multiline = True
WebBrowser1.Navigate("http:www.buyfixuse.com")
[code]....
If I activate this function in my application instead of links to the two blog posts on that website, it only gives out the text that is related to these links - (more...)

I'm just curious as to how some software programs that I see out there have the ability to extract links & text from thousands of web pages at an extremely high and fast rate. Has anyone here, ever created a link or text extracting program the has the ability to parse many webpages and return data into a textbox? I know how to extract links via the webbrowser control, but it doesn't seem to parse/extract data at a very high & fast rate like many email, link & text extracting programs that I see out there.

[URL].. called "The.Matrix.Reloaded.2003.mp4" so i tell my program to get the source code for the url [URL]..but it cant find the video's download link because it's searching for the file in the "continue" page's source code. you can see what i am saying by going to that website above and viewing the source code by right clicking on it. and then click continue and do the same when the video appears and you'll notice that the file is only there in the second one.
So my question is how can i get the source code for the page that the video is playing on and not the page where i have to click continue?
