I am trying to make a text spinner using regex. The format of the text that will be spun it {Hi|Hello|Hey there} my name is {Bob|Max|Robert}.
Some possible outputs:
Hello my name is Robert.
Hey there my name is Bob.
Hi my name is Bob.
I found some code but can't get to it to work:
Imports System.Text.RegularExpressions
Public Class Form1
Function Spin(ByRef value As String) As String
' Invoke the Regex.Replace function.
[Code] .....

i am new to programming but love to learn new things. I decided to jump in head first and write my own program on a whim one day. I've learned what I have so far through both books and online forums and help files.One thing I can't really seem to figure out, though, is how to implement a feature into my program.
I don't know if any of you will know what I'm talking about when I say that thing I want to program is my own article spinner. I've used them before, but all of the ones I have used require me to be online. I want to design my own for offline use.
The basics are this: You write an article in a textbox. Once you have that done, you go back and rewrite various words and phrases within the article using a format like this: {word1|word2} and {phrase one|phrase 2} and so on. Click a button and it saves your article to any number of text files using your unchanged words and phrases while also choosing just one of your words and phrases within the braces and between the bars.
i can use Regex matching to find urls in text, html source.But can Regex be used to get the link text (whats shown on screen) for that url it found e.g
<a href="www.mysite.com">Visit my site</a>
So for the above I want to return "Visit my site" Or do you just have to parse it.
I have 2 questions regarding replacing certain text in a string which has been found using regular expressions.For example this is my string:"<span style="font-weight: bold">This</span> is <span style="font-weight: bold">2010</span>"
i want to select the next piece of text which is underlined. You see the rtf of a richtextbox has following code for an underlines text :
uli0 hello friendulnonei
But the normal text looks like underlined. What i want to do is on a click of button the rtfbox should select the next piece of text which is underlined. An example piece of text is :
hello [friend your] house [looks] amazing.
imagine the words within square brackets are underlined. When i first click button1 "friend your" should be selected and on next click "looks" should be selected. Kind of keep moving forward and keep selecting it type of application. I know this can be done using regex but can't build a logic.
I'm needing to use Regex to find a dynamic text. It will always be found between the same things. Now, I'm sure that made little sense, so let me clarify. I have a rich text box full of text. I am needing to use a Regex method to find a certain string of that text that is always different. This string will be located between the same two pieces of text every time.
For Example: If this is my string: id ="user_name" ><img style ="display: block;" usr ="resentful" I need to find the text in between id ="user_name" ><img style ="display: block;" usr =" and ".
I just spent about 2 hours searching this forum on this topic but I need some advice. I am looking to extract certain data from HTML source code that I have down loaded into a text file its about 9KB in size.I am looking to keep all email address found. How would this work or what would be the best method to use? This is what I would like to extract and write to another file:
I have an application that downloads a .txt file via FTP, and then it calls some sql to insert the file data into my database. I want to check whether the file is in the correct format before trying to insert.
The file should consist of some number of rows, each with the following format:
(4 letter code) (tab) (3 or 4 letter code) (tab) (date as dd-MMM-yy) (tab) (variable length text description) (tab) (1 letter code)
Is there a good way to check whether every line in the file follows this pattern, and warn me if it doesn't?
I found a strange issue with the combination of RichTextBox and RegEx.If I load a text file into a RichTextBox and use
Dim matches As MatchCollection = Regex.Matches(RichTextBox1.Text, "^H(.+ ){10} ", RegexOptions.Multiline Or RegexOptions.IgnoreCase)
then the RegEx will run blazing fast.OTOH if I load the text from a file straight into a string and feed this string with RegEx.Matches using
Dim FullText As String = New StreamReader("c:TempTextFile.txt", System.Text.Encoding.UTF8, True).ReadToEnd Dim matches As MatchCollection = Regex.Matches(FullText, "^H(.+ ){10} ", RegexOptions.Multiline Or RegexOptions.IgnoreCase)
then the regex will run for ages.Now obviously the RichTextBox does something to the text. I found that loading the text into the RichTextBox will eliminate the first 4 bytes of the text (is that the byte order mark?). However, trimming those 4 characters with SubString won't solve the problem. RichTextBox does some other processing that I'm unaware of.I'm using RegEx both on client and server side (client can load text files into a RichTextBox to test and setup various RegEx's and the server will process text files according to these previously setup RegEx's). Needless to say that a regex will run blazing fast on the text file loaded into a RichTextBox, while the very same RegEx ran through the very same text file will seem to lock up the server side service.My question: what kind of text processing does the RichTextBox do and how can I mimic the behavior in a server-side process?
I am having an issue where I am using regex.Replace to replace part of a string. The basic idea is that I want to capture the beginning of the string then replace the end of the string with a value from code. For an example pretend I have a string that says "Test Number " followed by number and I want to increment that number. I capture the "Test Number " but when I try to concatenate that capture with the new number it treats the capture ($1) as a literal and replaces the entire string with $1[new number].
[code]...
This will output "We are on Test Number 2", as expected. how I can use a variable in the replacement string portion of the Regex.Replace when including a captured group?
I have a string which i need to parse using Regex class of System.Text.RegularExpressions. I need to find if the first 2 characters of the string are either "00" or "07" or "16" or "23".
I'm having trouble because I'm avoiding getting many blank spaces in the array after splitting. I'm trying to avoid using the optional | character but I get no results when I set it up without it!
I've spent much of the evening reviewing regular expressions and I've downloaded the following programs:
RegEx Designer.NET Antix RegEx Tester Expresso
I'm having trouble because the description contains a decimal point SOMETIMES and sometimes it doesn't. The description sometimes contains a whole number sometimes it doesn't.My friend recommended I use awk to divide it into columns. The thing is...I teach a Community Education class with Visual Basic .Net and I need to improve my RegEx skills.
I'm attempting to parse a text file containing several Windows paths; I'd like to use regular expressions if possible, and I'm using VB.NET.The file is formatted somewhat like so:
M - Network Mode C:ClientSystem - System Path C:ClientProducts - Product Path
I know it may be quite easily for you. i have a text which contains 40 lines, I want to remove lines which starts with a constant text. check below data.
When I used (?mn)[+CMGL:].*($) it removes the whole text , when I use (?mn)[+CMGL:].*( ) , it only leaves the first line. +CMGL: 0,1,,159 07910201956905F0440B910201532762F20008709021225282808 +CMGL: 1,1,,159
I've been hammering at this over the weekend with no joy - been through page after page of RegEx Language documentation too.It's very easy to negate a match on characters. For example:
Dim MatchString As System.String = "<test0><test0><test1></test1></test0></test0><test0></test0>" Dim NegationPattern As System.String = "([^<>])" Dim RepStr As System.String = ""
I'm creating a program in VB.NET to output multiple images. Some images will have the same file name. If there is multiple files with the same name I want to add "_1_" to the end of the file name. If the "_1_" file already exists I want to increment the 1 to be "_2_". If this file already exists I want to continue incrementing the number ultil it doesn't exist. So for example "filename", filename_1_", "filename_2_", etc. Here is the code that I have tried
