RegEx - Extract Body From HTML Source Of Any Website
Jul 11, 2011I 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())

View 6 RepliesHtml - VB Basic RegEx - Save Value From An Input Tag In HTML Source Code
Feb 16, 2011I 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.

View 4 RepliesExtract An Html Fragment From An Html Document?
Dec 8, 2010I'm looking for an efficient means of extracting an html "fragment" from an html document. My first implementation of this used the Html Agility Pack. This appeared to be a reasonable way to attack this problem, until I started running the extraction on large html documents - performance was very poor for something so trivial (I'm guessing due to the amount of time it was taking to parse the entire document).[code]...

Feb 10, 2010I am using VB.net to send my mails through outlook. Where i am giving the resource path for the pictures inserted in to it.

VS 2008 Using Regex To Extract All Ips And Ports Using Webcontrol?
Mar 27, 2009I 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

Regex To Extract Cell References From Excel Formula To ArrayList?
Jan 5, 2009Has anyone created a regex that matches each of the cell references in a given Excel formula? I'm trying to extract a list of cell references into an ArrayList from a provided Excel formula. Ideally, the ArrayList would also preserve any cross-tab or cross-workbook reference information. The key is for the regex to be compatible with any potential Excel formula, as the formula will change with each use.This seems to capture cross-workbook references:

Aug 23, 2010This may take some explaining but the concept is pretty simple. A user will select a file which contains data that they wish to extract from, so keeping it simple they pick a file like so:
[Code]....
So, I need to show the user the file, allow them to select a line to match and/or extract from. So they select the first line ready for a match, they then select a word/s to mark as a constant for matching, so in this case it would be: MyGroup A simple version for text match would be like "MyGroup *" Now, I need to convert this to regex dynamically (I assume its the best method), its not a one off, the data that is selected is all open and up to user selection. There could be multiple selections and multiple extractions on the same line!
