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?

WebClient.DownloadString Not Getting Whole HTML String

Nov 11, 2010

I'm working on a project that scrapes data from government websites. I've noticed that whenever I use WebClient it doesn't always get the whole HTML code. Even when I get the robots.txt file it doesn't return everything. For example, http://www.bbc.co.uk/robots.txt has 80 lines but I'm only getting 13 lines.

If an HTML block uses "display: none" in the style I can't get anything between the hidden HTML blocks.Here is the sample code I'm using:[code]...

Webclient Getting A Internal Server Error When Downloading A String?

Nov 12, 2011

My program takes user input, replaces all spaces with "+", then inserts it into a search url for a specified web host. For example, the user enters:"How long is a foot?"

The generated URL (in this case I'm using dogpile.com) is:

"http://www.dogpile.com/info.dogpl/search/web?&q=How+long+is+a+foot"

This method has worked before for me, but now I just get an Internal Server Error every time the code is executed.

RegEx - Finding Pattern In String

Jul 22, 2009

I'm trying to find a pattern in a string, I guess is very easy but I'm terrible in regular expressions. I have a big text and I need to find all the next type of pattern:
{a|b|c}
That can be also something like this: {a|b|c|s|f|f|ft|r} or any number of items inside but at least 2 items so the pipe symbol is another key. Is this an easy regular expression? I'm using vb.net 2005.

Regex To Return Part Of String?

Jun 2, 2011

I'd like to parse out the Version V3.5/7(030114) part using a Regex or Substring, but not sure how. The surrounding text could be dynamic in length and the 6 numbers between the parenthesis could be a different length as well (maybe 4).

how would I get just that string out?

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.

Will the code shown below be upto the mark for this.
