.net - Read A Specific Line From An Html Source Code?
Jun 25, 2012
I want to read a specific line from an html source code. Im storing the source into a string file and i want to read the line X.So im using this method that i found on net
Public Shared Function ReadSpecifiedLine(file As String, lineNum As Integer) As String
Dim contents As String = String.Empty
Try
Using stream As New StreamReader(file)
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?
Way 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.
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:
I'm trying to extract the text fields inbetween the code but the text is always changing so I'm not sure how to keep this dynamic. In put them in to the proper text boxes.
So text box 1 might be Date: then it pulls the date.
and there are multiple listings. so I need it to loop until the end of </table>
I am using WebBrowser1.DocumentText to get a websites source code, and then parse a string. I am trying to view the source line by line, and doing it as follows:
[Code]...
However what is displayed is each character from the source code, rather than the line. I am making the client log into a website, and the needed value from the source code is then parsed, so I need to use the WebBrowser type to get the source code.
Trying to split a giant string that is the source of an HTML document after performing an httpget and read the lines into an array while removing empty lines. The following code does not work for me just puts the same string into the array at position (0) without splitting it.[code]...
How to get source/HTML code of the web page that is shown in WebBrowser1 when I click a button? I would like it to be written in Notepad or eventually in new form..
I'm writing a program in VB.net that gets the source code of a web page with a video on it. it then uses regular expressions to isolate the download link of that video. then it uses "httpwebrequest" and "httpwebresponse" to download the video. my problem arises when certain sites have a page where you have to click continue in order to get to the video page. [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?
