Hi everything,  
Can anyone help me on this

Str1 = "system.exception unable to find a click sleelector.

Type into click aqaes test knfkajfkaguwbdiwndkdb  
Wnajjskdjfjdjdjjwwhn wiwnd exception edjf fmjsnhjwnwh"

Str2 ="System.exception unable to find a click sleelector.

Type into click aqaes test knfkajfkaguwbdiwndkdb  
Wnajjskdjfjdjdjjwwhn wiwnd exception edjf fmjsnhjwnwh"

When I’m using if condition like

Str1.trim().contains(str2).trim()

Above 2 string as same letters space everything but still it is falling in false.

Hi @Arya_Squares

You can use this site to compare text

[Text Compare! - Find differences between two text files (text-compare.com)](https://text-compare.com/)

in your case, contains method is case sentitive You can check using this:

```auto
Str1.ToLower().Trim().contains(Str1.ToLower().Trim())

```

it will convert the strings to lowercase before compare

Hi,

There might be difference regarding white space.  
Can you try the following expression?

```
System.Text.RegularExpressions.Regex.Replace(str1,"\s+"," ").Contains(System.Text.RegularExpressions.Regex.Replace(str2,"\s+"," "))

```

Regards,

It seems the issue might be with white spaces. Try this expression for a more robust check:  
System.Text.RegularExpressions.Regex.Replace(Str1, @“\s+”, " “).Contains(System.Text.RegularExpressions.Regex.Replace(Str2, @”\s+", " "))
