How To Use RegEx Expression With InSTR

Jan 13, 2011

I'm looking to do is scrub an html file for anything that resembles an IP address or any set of numbers for that matter. Normally what I would do is just using things like string.split to split out the html around areas that I want to search. What I am looking to do is be able to essentially search a large amount of characters for anything that matches this reg ex pattern.

Dim pattern As String = "^(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]):(d{1,4}|[0-5]dddd|[0-5]dddd|6[0-4]ddd|65[0-4]dd|655[0-2]d|6553[0-5])$"

GetWebId$ = Regex.Replace(LCase$(strNote$), strPattern$, strReplacement$)

C# - How To Write A Multi-line RegEx Expression

Jan 12, 2010

I have a vb.net class that cleans some html before emailing the results.

Here is a sample of some html I need to remove:

<div class="RemoveThis">
Blah blah blah<br />
Blah blah blah<br />

[Code]...

I am already using RegEx to do most of my work now. What would the RegEx expression look like to replace the block above with nothing?

I tried the following, but something is wrong:

'html has all of my text
html = Regex.Replace(html, "<div.*?class=""RemoveThis"">.*?</div>", "", RegexOptions.IgnoreCase)

Nov 14, 2011

I am trying to build an application which does the following :

1) write some text in a richtextbox

2) when user clicks a button, the app will replace the text with another text in {} braces.

Regex - Parsing Excel Reference With Regular Expression?

Oct 14, 2010

Excel returns a reference of the form

=Sheet1!R14C1R22C71junk

("junk" won't normally be there, but I want to be sure that there's no extraneous text.)I would like to 'split' this into a VB array, where

a(0)="Sheet1"
a(1)="14"
a(2)="1"

[code]....

I'm sure it can be done easily with a regular expression, but I just can't get the hang of it.

VS 2010 Proper Regular Expression (Regex) Pattern?

Apr 24, 2012

It seems up until now I've never used Regex, nor even heard of it. But once I did I realized how extremely useful this is. Having said, it's been 2 days since I've began looking into constructing my own patterns. My most recent being for decimals. Is the pattern I provided below "proper"? and are there also any improvements I could be making for a more efficient patter, which would minimize any possibility of a loophole? [code] So for my use, this is doing what it's supposed to being doing under every test I can through at it. But do mind the 0. and .0, I have a function to normalize these as they are proper, I just pad the left and right accordingly. I found most regex questions asked here..and yes I am doing this in vb.net so it fits. If not, then feel free to move this post somewhere else better suited for the topic of discussion.

Regex - Regular Expression To Convert Ul To Textformat And Back, With A Different Attribute Value For First Tag ?

Apr 1, 2010

This is a related to a previous question I have asked here, see the link below for a brief description as to why I am trying to do this.Regular expression from font to span (size and colour) and back (VB.NET).Basically I need a regex replace function (or if this can be done in pure VB then that's fine) to convert all ul tags in a string to textindent tags, with a different attribute value for the first textindent tag.For example:

<ul>
<li>This is some text</li>
<li>This is some more text</li>[code].....

Basically I want the first ul tag to have no indenting, but all nested ul tags to have an indent of 20.

Regex - .net Regular Expression To Match Two Words Separated By Comma Not Working?

Mar 4, 2010

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 & "#"

Regex - Mass Search And Replace With Wildcards Or Reg Expression MyString.Length To Len(MyString)

Oct 14, 2010

I have a large ASP.NET project where I want to do a mass search and replace (about 3500 instances)

I want to change

If strErrorMessage.Length > 0
If strSomeString.Length > 0
If strWhatever.Length > 0

and any other similar call to the Length method from a string to the following

If Len(strErrorMessage) > 0
If Len(strSomeString) > 0
If Len(strWhatever) > 0

Anyway to reliably do this in one shot?

I can do a search and replace for something like If *.Length > 0 --> If Len(*) > 0

This just won't work though as it won't understand how to rearrange it properly. Currently have VS2010 and N++ at my disposal.

Each textbox can be changed and there is a nice scroll bar at the bottom to move left and right as you enter each datapoint.

I tried using multiple tabs within a Panel and setting the Appearance to FlatButtons, but the text area under each tab gets covered when you select another tab.
