Summary

Here is the basic implementation of the regular expression (Regex) in UFT API

Question

Notes:

- The only statement needed to make this work is the declaration:
"Using System.Text.RegularExpressions; ..."

- The regex has nothing to do with checkpoints but from here you can use it
define a checkpoint.Report or whatever

- The regex code can be defined on any event

Answer

Implentation:

1. Regex requires declaration at the top of the script:
using System.Text.RegularExpressions;

enter the statement at the top of script TestUserCode.cs

Example:

namespace Script
{
    using System;
     ...
    using System.Text.RegularExpressions;

    [Serializable()]
    public class TestUserCode : TestEntities
    {
      ...

2. Regex sample code
    The code can be defined on any event

//Define variables
string sText;
bool bRxMchFnd;   //true/false

sText = "abcd";

this.Context.UserLogger.Info(" String: '" + sText + "'");

//- Pattern found
var RxMatch = Regex.Match(sText, "bc");
bRxMchFnd = RxMatch.Success;       //True
this.Context.UserLogger.Info(" Match 'bc': " + bRxMchFnd);

//- Pattern NOT found
RxMatch = Regex.Match(sText, "xxx");
bRxMchFnd = RxMatch.Success;       //False
this.Context.UserLogger.Info(" Match 'xxx': " + bRxMchFnd);

Output

String: 'abcd'
Match 'bc': True
Match 'xxx': False
