View 3 RepliesDim abc = WebBrowser1.Document.GetElementById("old_sl")
Dim theElementCollection As HtmlElementCollection = abc.GetElementsByTagName("option")
For Each curElement As HtmlElement In theElementCollection
Dim controlName As String = curElement.GetAttribute("value").ToString

I have the same problem as this poster, however I am using a .net gridview and would like render my html to use the fix offered here.Using CSS to create table cells of a specific width with no word wrapping. EDIT I think I may be going about this all wrong, maybe you don't change the rendering by extending the BoundField, but rather add the properties to the boundfield then change the way the gridview renders its fields based on the properties of those fields.Which also leads me down the path of control adapters,
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.

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>

View 4 RepliesI 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.

View 1 RepliesHow in VB.Net can I extract the value from a string using the RegularExpressions class? For example, say I have the string:[Mon Jan 4 2011] Blah Blah2 Other text and I want to return the "Mon Jan 4 2011" portion in to a variable. I thought you would use the "Regex.Replace" method but I can't seem to figure out how to extract the portion of the string I want.
