I am trying to extract everything between the body part as I am building a forum crawler
and since all the user posts are between the <body></body> I have chosen to experiment
with Regex. So far I have coded the following but sort of stuck on how to output the result say in a textbox? Also I am not sure if the body part of the regex is correct.
Dim URL As String = Textbox1.Text
Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("URL")
Dim response As System.Net.HttpWebResponse = request.GetResponse
Dim streamReader As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream())

Something is wrong with this function. It verifies the first word of string. After that it doesn't return anything.

I am trying to split a long string based on an array of words. For Example:Words: trying, long, array Sentence: "I am trying to split a long string based on an array of words."Resulting string array:Multiple instances of the same word is likely, so having two instances of trying cause a split, or of array, will probably happen.

I have a textbox with a large amount of data, but I am trying to extract only the following into an array: only 3 or 4 letter, uppercase words. The goal is to find all stock symbols within a document.
For example, in this post, if I were to type "MSFT", regex would extract MSFT because it is a 4 letter, uppercase word.

Im trying to extract ALL urls from a webpage in between two sets of strings.
I have the code to extract all links, but I am
href="http://www.blah.com/yadayada?tf=info"
Using regex; I want to grab everything between href=" and the quotation mark at the end .
This was a snipit I found that works for extracting in between 'href="' and </a>
HTML
Regex.Matches(data, "href=""(.*?)"".*?>(.*?)</a>")
I learn best by example, and I tried piecing it together by comparing the regex match above, to a URL in between hreft" and </a> - but I couldnt do it. Ive been working on this project for a while, and im getting tired.

I am pretty good with perl regular expressions but evidently I am at a loss on why this doesn't work.The code below stores "Person Test" in output variable.
im output As String
Dim userName As String = "Test, Person"
Dim re As New Regex("(w+),s(w+)", RegexOptions.Singleline)
output = re.Replace(userName, "$2 $1")
So why doesn't the following code store "#Test##Person#" in output variable.
Dim output As String
Dim userName As String = "Test, Person"
Dim re As New Regex("(w+),s(w+)")
For Each Match As Match In re.Matches(userName)
output &= "#" & Match.ToString & "#"
Next

I have been stumped on this for about 3 weeks now. In the beginning me and my partner have been trying to hit this at the internal angle. only problem is different html tables are constructed different than others. We are needing to extract from multiple pages and sites so we know that Regex will be the best solution. We can use the same script for everything. This is my first time working with Regex, I got it actually extracting the very first ip[proxy]. I have no idea why it isn't extracting every one on the page. I also have to add the . in between each each octave of the ip. That is weird because I have it in the Regexpession to find the .'s.What I'm Needing is for this to basically scan the whole page and grab all the ipsorts and add them to a listbox.Here is my
Dim request As HttpWebRequest = Nothing
Dim response As HttpWebResponse = Nothing

[FirstName] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, [MiddleName]
[varchar](50) COLLATE SQL_Latin1_General_CP1_CI_A
What I want is regex code which I can use to get all fields and data type. So will return something like that:
FirstName varchar
MiddleName varchar
The sql statement will always have this format. I am using .Net to run this regex
