Regex.Replace With A String Of HTML

Jun 25, 2009

I have a long string of HTML code that contains several quotes around objects in the string. I have a Regex.Replace() function to change the "img src" tag, due to the way its stored in a database.

Here is my string: <p><strong><u><font color="#cc0099">RICH TEXT BOLD UNDERLINE. PICTURE TO APPEAR BELOW</font></u></strong></p><p><strong><u><font color="#cc0099"/></u></strong></p><p><img src="/inlineimages/WorkOrder/6/1245981403232.jpg"/> </p><p /><p>W00T!</p>

[Code].....

Notice how the "<font color=" has single quotes around its value, and "<img src=" has single quotes, with a double quote jammed in between?

Also, is there an automated way to go from my initial string, to the "Dim input As String" I created? I had to manually type that out, editing the quotes just to try and make it work.

Sep 10, 2011

Dim s1 As String = "START (random string) FISH bingo CAKES (random string) END"

Html - VB Basic RegEx - Save Value From An Input Tag In HTML Source Code

Feb 16, 2011

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:

<input class="someclass" type="hidden" value="3" name="user_status" />

I just dont understand regex enough to cope with these situations.

VS 2008 String IndexOf And Remove VS Regex?

Oct 11, 2009

I have a string with 60000+ characters. I look for informations inside the string in a sequentially order. Every time I found a information I delete whatever is behind that information. In other words I reduce the size of the string every time I find something, and I do this using IndexOf and Remove, much like this:

vb.net Str = Str.Remove(0, Str.IndexOf("MyInfo"))

This can be quite heavy on the processor. So my question is it faster to look the informations using Regex or it would be about the same?

VS 2008 - Using RegEx String To Validate Email Address?

Feb 11, 2010

I am using this regex string in one of my programs to validate email adresses: "^[a-z0-9._%+-]+@[a-z0-9.-]+.[a-z]{2,4}$". This works well for the most part, but I just found out that it doesn't catch an address like this ... "john.doe.@yahoo.com" ... where there's a "." right before the "@", which is invalid, so my program tries to send it & throws an exception. How to modify my regex string to catch this situation?

HTML - Regex To Remove Quotes From Img Tag?

Mar 9, 2011

I need to remove all quotes from an image tag found within lots of other text. For example, I want to make

<img src="folder/image.gif" target="_blank" />

into

<img src=folder/image.gif target=_blank />

I'm using vb, and need to use a regEx specifically for the img tag and not use replace. The img tag can be in a block of other text, so I need to use regEx to search for the <img and then within that until I meet a /> I need to remove all quotes.

Regex To Parse HTML Tables

Dec 19, 2010

I am trying to remove the tables within an HTML file, specifically, for the following document, I'd like to remove anything within the tags <TABLE....> and </TABLE>. The document contains multiple tables with texts in between.

The expression that I came up with, <TABLE.*>s*[s|S]*</TABLE>s*, however would remove the text in between the tables. In fact it would remove everything between the first <TABLE> and the last </TABLE> tags. I would like to keep the texts in between and only remove the tables.

HTML Tag Replacement Regex Not Quite Working Correctly?

Sep 14, 2009

This is a follow up to another question of mine. The solution I found worked great for every one of the test cases I threw at it, until a case showed up that eluded me the first time around.My goal is to reformat improperly formatted tag attributes using regex (I know, probably not a fool-proof method as I'm finding out, but bear with me).

My functions:
Public Function ConvertMarkupAttributeQuoteType(ByVal html As String) As String
Dim findTags As String = "</?w+((s+w+(s*=s*(?:"".*?""|'.*?'|[^'"">s]+))?)+s*|s*)/?>"
