hello..,

this is some part of my text document,please try to find some regexp

It was with that end in view that provisions were enacted in the impugned Act for speedier trial of the said offences by the appointment of Special Judges who were invested with exclusive jurisdiction to try the same and were also empowered to take cognizance thereof without the accused being committed to them for trial, and follow the procedure prescribed for the trial of warrant cases by magistrates. The proceedings before the Special Judges were thus assimilated to those before the Courts of sessions for trying cases without a jury or without the aid of assessors and the powers of appeal and revision invested in the High Court were also similarly circumscribed.

i have to enter two wods like appointment, committed .so it will skip the word btwn this two and hightlit this,also skip special char . , : ? / \ ( ) { } [ ] % $,and dates format

i also find something.

appointment (\ [a-zA-Z]*){0,20}\ committed

also concider Spaces ,pargraph if possible

thanks in advance.

Hello, Here is a solution using two regular expressions. It is very basic and I hope it will help or give you some starting point. I've not yet found a single regexp solution. The idea here is that you match the first string and then you create another string from the match point on and try to math the second string. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Text.RegularExpressions; namespace RegExp { class Program { static void Main(string[] args) { string pattern = @"dogs"; string pattern1 = @"food"; Regex reg = new Regex(pattern, RegexOptions.IgnoreCase); Regex reg1 = new Regex(pattern1, RegexOptions.IgnoreCase); string str = "Dogs are hungry, and we should give them food."; string str2 = string.Empty; Match m1, m2; m1 = reg.Match(str); if (m1.Success) { string value1 = m1.Value; int index = str.IndexOf( value1, 0 ); str2 = str.Substring(index + value1.Length ); Console.WriteLine("m1 = " + m1.Value); m2 = reg1.Match(pattern1); if (m2.Success) { string value2 = m2.Value; Console.WriteLine("m2 = " + m2.Value); } } Console.ReadKey(); } } } Also, you can try this link to find out more on regular expressions: http://www.regular-expressions.info/tutorial.html.
