Html - Grab Webpage Table Data (using Span Class Element) Into Listview Control In App?
Feb 20, 2012
I need to grab some data from a webpage but for me the main problem is I can't grab the data the way I want. I want to grab the data in a listview control but my code is fetching all data within any span tag (span class "inputFieldLabel" which is not required) in a single column of a listview control. I am giving the format (source) of the webpage below and my coding in vb.net (2008),
<br>
<span class="inputFieldLabel">Following Are ...</span>
<span class="inputFieldLabel">01/02/2011</span>
<span class="inputFieldLabel">And</span>
[Code].....

1. How do I exclude a string that is matched?
I have something like this:
You answered question 1 correctly. You have been awarded
<a href="url"> 1 point</a> .
You answered question 2 correctly. You have been awarded
<a href="url"> 1 point</a> .
You answered question 3 correctly. You have been awarded
<a href="url"> 1 point</a> .
You answered all 3 questions correctly! You have been awarded a total of
<a href="url"> 3 points</a> .
So basically I want to filter out all those in bold, it should look like this when printed to a textbox:
You answered question 1 correctly. You have been awarded 1 point.
You answered question 2 correctly. You have been awarded 1 point .
You answered question 3 correctly. You have been awarded 1 point.
You answered all 3 questions correctly! You have been awarded a total of 3 points.
2. How do I get a value of HTML span element? (I'm not sure how to phrase this but I think you will get it if I show a example..)
It goes something like this...
<span class="quiz1">Question 1:</span>
<span id="q1">Question Here </span>
I want text in bold to be displayed in a label. Do I use getAttributeByID here? How do I use it in VB.net?

What I'm trying to do is click an html link inside of a html table via code in vb.net using a web-browser control. The link I want to click can be anywhere in the first column of the table so I need to cross reference with another column in the table to make sure I have the re way I'm going about this is to loop through the html elements till I find the table I want (multiple tables on the page) then dump that table to an array. Then loop through the page again get to the table I want and then start comparing the link and another column in the now array. I need to check to make sure that the url of the link contains a work and that another column in the table contains a specific or lower numerical value. Basically where I'm stuck is while dealing with the html element "Table" wanting to identify and interact with another html element inside it.
'Flag to say dump to array
Dim RecordFiles As Boolean = False
'The last two headers in the table are blank so need to skip them
Dim FirstBlank As Boolean = False
Dim SecondBlank As Boolean = False

I decided it's time to migrate from VB6 to VB.NET and am currently translating my radio player but have run into several issues so I might be on this forum for the rest of the day... Anyway, in VB6 I used Inet to get the source of a PHP page that had the current song that was playing on the SHOUTcast stream. I can't seem to get Inet to work and figured I would just look for another method so I wouldn't need to pack msinet.ocx along with the finished product.
How can I get the source of the PHP page and store it in a variable or textbox/label.

I have the following on my interface / webform: <div id="mydiv" class="forceHeight" runat="server" />
now I have a dondition in my code behind where if a certain situation is true I need to remove the forceHeight class from this control. I know in C# you can use:
mydiv.CssClass.Replace("forceHeight", ""); I'm not so sure how you do this using VB? Intellisense doesn't offer me this option?

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 understand the basics of httpwebrequest and I'm not looking for any answers on web browsers. My previous method was done using webbrowsers but because of the lack of speed I have transferred over to httpwebrequest to speed up the process.
I have an id of an element that I would like to grab and use in an httpwebrequest but not sure where I would start with that.

I am looking for a regular expression that can convert my font tags (only with size and colour attributes) into span tags with the relevant inline css. This will be done in VB.NET if that helps at all.I also need a regular expression to go the other way as well.To elaborate below is an example of the conversion I am looking for:
<font size="10">some text</font>
To then become:
<span style="font-size:10px;">some text</span>
So converting the tag and putting a "px" at the end of whatever the font size is (I don't need to change/convert the font size, just stick px at the end).The regular expression needs to cope with a font tag that only has a size attribute, only a color attribute, or both:
<font size="10">some text</font>
<font color="#000000">some text</font>
[code]....
I also need another regular expression to do the opposite conversion. So for example:
<span style="font-size:10px;">some text</span>
Will become:
<font size="10">some text</font>
As before converting the tag but this time removing the "px", I don't need to worry about changing the font size.Again this will also need to cope with the size styling, font styling, and a combination of both:
<span style="font-size:10px;">some text</span>
<span style="color:#000000;">some text</span>
[code]....
I am extracting basic HTML & text from CDATA tags in an XML file and then displaying them on a web-page.The text also appears in a rich-text editor so it can be edited/translated, and then saved back into a new XML file. The XML is then going to be read by a flash file, hence the need to use old-fashioned HTML.
The reason I want to convert this code is mainly for display purposes. In order to show the text sizes correctly and for it to work with my rich text editor they need to be converted to XHTML/inline CSS. The rich text editor will also generate XHTML/inline CSS that I need to convert 'back' to standard HTML before it is saved in the XML file.I know the temptation will be to tell me a number of different ways to set up my code to do what I want but there are so many other permutations I haven't even mentioned which have forced me down this route, so literally all I want to do is convert a string containing standard HTML to XHTML/inline CSS, and then the same but the other way round.

I have used .NET and ShDocVw for years to grab data off webpages without any issues I couldn't overcome. This website has me beat though. It seems like such as easy task to grab the titles and other information off a library search page, but I can't see the data to be able to grab it. Usually, I just look in the DOM, but the data wasn't there. I did a view source, but the data wasn't there.

I am building the 'TheBeerHouse' project in vb.net (the book is written in C#). Once I understand the concepts, I can usually convert it to vb. However, there are a few areas that give my some problems (which I will address individually). The first issue I have is the C# 'base' to VB 'MyBase'. [code] My understanding of this conversion is that I need to grab the attributes of the <articles> element under the <theBeerHouse> custom section in the web.config file.This code does not compile and the get the following error: 'MyBase' must be followed by '.' and an identifier.
