How to transpose a word using Regular expression search and replace

[Babu Mannaravalappil]

Hi,

I want to replace some words in my text files (actually transpose).
For example, I have a whole lot of expressions (words) in my files as
follows:

TABLECUSTOMERS
TABLEORDERS
TABLEORDERLINES
....
....
....

I want to replace them as follows:

CUSTOMERSTABLE
ORDERSTABLE
ORDERLINESTABLE
....
....
....

How can I do this using regular expression search and repalce?

Babu.

Babu,

Use a pattern of "\bTABLE(.*?)\b", and a replacement string of
"$1TABLE".

Here's an example in C#:
using System;
using System.Text.RegularExpressions;

namespace Main
{
public class MainClass
{
[STAThread]
public static int Main()
{
string input = @"
TABLECUSTOMERS
TABLEORDERS
TABLEORDERLINES
";

Console.WriteLine(SwapWords(input, "TABLE"));

return 0;
}

public static string SwapWords(
string input,
string word)
{
return Regex.Replace(input, "\\b" + word + "(.*?)\\b",
"$1" + word, RegexOptions.Singleline);
}
}
}
