Doing Some HTML Parsing?

Apr 11, 2010

I'm having some trouble putting the pieces together.First of all, I'm currently using the WebBrowser component, but would be plenty happy with HtmlAgilityPack if it had some decent documentation, but for a newbie as VB.Net, it's a rough road.

<h3 class="this-class">
<p><a href="file.html">Title</a></p>
</h3>

[code]....

What I'd like to do is grab all the h3's with the "this-class" class and stash them into an array (one in each array element).I'd then like to search through each one and see which has "And Another Title" - which I already have the code to do... I just don't know how to do the first bit.

1.If I run 100 threads with this function at the same time, Will it work?

2.Won't it affect my internet connection as well?

I don't want to waste time creating threads and codes a hundred times so if you know the answer please advice me on what should I do instead

2008 Parsing HTML

Jan 26, 2009

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?

Parsing HTML - Reading A Particular DIV?

May 1, 2011

I need to parse a web page for blocks that contain open trouble tickets. The web page display several unresolved tickets and each one is inside a html divison labeled "issue-status". I've written the following code which does find the blocks, but when I try to parse its children to get its element fields (date opened, person requesting, history...) it instead pulls every element from the web page, not just the children.Is there a way to just parse the sub-fields under a particular DIV?

Code:
Dim theElementCollection As HtmlElementCollection
Dim strResult As String = ""

Parsing / Reformatting HTML To Text

Nov 9, 2011

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

Parsing Links Out Of A HTML Document?

Sep 1, 2009

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...)

VS 2010 Parsing Many HTML Tags?

Jul 27, 2010

This page here has a table I need to parse.

It has multiple tags like this:

<td style="text-align: center;"><img src="http://www.pkmdb.com/res/icons/001.png" alt="Pokemon" /></td>
<td style="text-align: center;">001</td> <td style="text-align: center;"><a href="http://www.pkmdb.com/DL/PKM/bulbasaur.pkm">Bulbasaur</a></td> <td style="text-align: center;"><img src="http://www.pkmdb.com/res/types/grass.png" alt="Type" /></td>Different Number, different name. I need a way to get the number and name out of these tags. I'm rather terrible at this, and I've seen examples on the site, I just don't know where to start really on this.

VS 2010 Parsing Data From HTML Into VB2010?

Sep 24, 2011

Let me preface this by saying I'm VERY limited in my programming knowledge/experience using any language. I mean I have extremely basic capabilities and don't quite understand this stuff inside and out like most of you do.Anyway, I'm trying to code a fantasy football draft program in VB 2010 that utilizes the MS Internet Transfer Control 6.0. It will retrieve the HTML from a website, say ESPN, and parse the data into player names, rankings, and other stats. Should all be simple strings/sub-strings. It will then populate a DataGridView control so that each row in the DGV has the player's name, ranking, projections for the season, etc. After this has been populated, the program will be designed to allow me to draft players and assign them to the various teams automatically. I am the commissioner and we do an off-line draft, so I will just make picks for everyone and submit them online later.

Dim root As HtmlNode = doc.DocumentNode
Dim anchorTags As New List(Of String)
For Each link As HtmlNode In root.SelectNodes("//a")
