Hi,

Can you try to add full namespace (System.Text.RegularExpressions.) as the following, for example?

```
System.Text.RegularExpressions.Regex.Match(yourString,"\d+",System.Text.RegularExpressions.RegexOptions.IgnoreCase)

```

Regards,

Hi @Gayathri_Mk

Ensure that you have imported the necessary namespaces: Verify that you have imported the `System.Text.RegularExpressions` namespace in your UiPath project.

```auto
System.Text.RegularExpressions.match

```

Gokul

Hi,

How about the following?

```
System.Text.RegularExpressions.Regex.Matches(output,"^\s*\d{6}\s+[\s\S]+?(?=Plan Total)",System.Text.RegularExpressions.RegexOptions.Multiline).Cast(Of System.Text.RegularExpressions.Match).Select(Function(m) m.Value).ToArray()

```

Just a bit curious, why don’t you use the default activity for RegEx Matching?

@Gayathri_Mk

For amount we can use `output(0).Split({"$"},StringSplitOptions.None)(1)`

For getting date the type of loan if you have a  
List of available values it is better to match it as it is beside a name only like say the possible values are `{"Distribution","Initiate Loan"}` stored in an array arr1 then `use arr1.First(function(x) output(0).Contains(x))`

Now as you know the matched type value replace that from the output(0) and then extract only the name before the date to get the name value using expression `.*(?=\d{2}/\d{2}/\d{4})` …In the resultant value initiate loan can be replaced as it is already identified in previous step and can get the name

Hope this helps

Cheers

As stated above you can get name plus the type using the above regular expression

And if you know the different types that are possible then we need to use as below to check if that is present

> [@Anil\_G](#):
>
> `{"Distribution","Initiate Loan"}` stored in an array arr1 then `use arr1.First(function(x) output(0).Contains(x))`

Then use replace activity to replace and only get the name

Cheers

@Gayathri_Mk

if we have a tab separator then try this

`Regex.Split(str,"\t\n?")`

Or try with below

`Regex.Split(str,"\s{2,}")`

Cheers
