[code]The two parts I've coloured red change, I need to grab the first part which is the link but I'm not sure how to do this. I've used regex before and it doesn't look possible to use it on this on this, there's about 25 of these in the source.

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.

Need a bit of help with HTML Agility Pack!Basically I want to grab plain-text withing the body node of the HTML. So far I have tried this in vb.net and it fails to return the innertext meaning no change is seen, well atleast from what I can see.

htmldoc.LoadHtml(html)
Dim paragraph As HtmlNodeCollection = htmldoc.DocumentNode.SelectNodes("//body")

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.

I'm a PHP/MySQL/HTML guy, but in the course of my work, I sometimes have to delve into Gatesland.I am working in VS2005 developing reports, and occasionally I have to write some custom code. This code is in (I believe) VB.NET. I avoid this as much as possible. It is my belief that if you have to use custom code in a report, you're doing something wrong with the DB, or with your query.Now, my boss (for reasons unknown) is storing data in the database as HTML. This data is historical, having a month and a dollar amount, and comes in a form like this:[code]I know this breaks even 1NF. I did not design the database. I simply must suffer under it's schema. See, the developer did this so that he could just read in a field, and dump it straight out to an echo/print statement when forming up the HTML. Unfortunately for me (the report developer), HTML shows up as verbose text if I dump it out as a field in a text field in a VS2005. So, I need to strip out he HTML tags, and replace them with appropriate values.
I am first trying to strip out the <th> data, and print it out with appropriate line feeds and carriage returns. This is the code I am trying to use:[code]Now, far from doing what I intend it to do, it simply returns the jubilent result "#Error". Wonderful. I'm sure the client will be happy.There must be some simple syntax errors or something going on there, but I am nowhere near an expert with VB.NET. I've used VBA extensively, but last time I used it was about 3 years ago. I'm hoping I can cash in some of that positive rep I've got, and get some much needed help in the dark wilderness of Microsoftia

The method I'm currently using to extract html and the parse is via a WebBrowser control. I'm grabbing a collection of tags, sorting through the ones I want, and then pulling the innertext.
Doing this on my development machine is kind of slow, but manageable. At max, I can go through 60 different web pages across 3 different sites. It takes about 5 mins on my machine.
However, this app is targeted towards machine that have a quarter of the technology that my computer has. So, it takes anywhere from 10-15 minutes. This is less than ideal.
Does anyone know of any other method that I could do that would take less resources and perform a lot quicker?
I noticed no way to modify color at all with textbox, is this accurate? no way to enable html parsing, etc...richtextbox can without enabling html(better because scripting using html like font size, etc...can be un-desirable to allow all html...

I successfully wrote a code to retrieve a version number from a HTML page which is this:
<div class="header">Latest Version: <span class="version">6.59</span></div>
So the following code will return the version number which currently is 6.59 which is what I'm after. [Code] But then i remembered that releases are done as following: 6.59, 6.59b, 6.59c, 6.60, 6.60b etc. So when the b version of 6.59 is released the parser will still return 6.59. So how can i make this code better?

I have used examples from threads here on how to open and convert word documents to html in order to parse them. I got it all working great using the office interop library but used an example word document with some text in it and it worked fine. Now with actual word documents that I need to parse that come in all types of formatting and irregular formats I got it to convert to html all fine. But the actual html when looking at it does not make sense and I am not sure how to parse this. for example:
LsdException Locked="false" Priority="72" Name="Colorful List Accent 5"/>
<w:LsdException Locked="false" Priority="73" Name="Colorful Grid Accent 5"/>
<w:LsdException Locked="false" Priority="60" Name="Light Shading Accent 6"/>

I have this code that gets text from a webpage.
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted

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 need to string z from a webpage source file but having trouble cutting the code around it away.
I am using an API (WSUS) that will give me an XML fragment that I need to work with. Essentially, I need to go through the fragment element by element, identify what type of element it is, and then put that element into the datagridview. The goal is to have a column with a human readable interpretation of the element, plus that actual element itself in a hidden column for further processing. So, using the below XML, I want the DGV to have column that says "Begin Or Group" and a hidden column with "<lar:Or>".
I can get an xmltextreader to loop through the elements just fine, but I can't figure out a way to return just the current element in XML. I've tried ReadString, Value, ToString, and a bunch of other stuff but just cannot seem to figure it out.
Here's an example fragment:
<lar:And>
<lar:Or>
<bar:WindowsVersion Comparison="EqualTo" MajorVersion="5" MinorVersion="0" ServicePackMajor="4" ServicePackMinor="0" />

I'm developing an app for WP7 and Win7 that will get info extracted directly from particular websites. The app will download the HTML source and parse through it to find the required strings. The strings may not have tags. note multiple instances of the string needs to be found. I've tried a few very rudimentary ways, and although they work, they are extremely slow.
