How to uniquely identify field using regex pattern?

[Vaishnav_Tej]

Hi all,

I’m trying to extract the value of field “Total” using Regex Pattern of “Matches” Activity.

Fields available :
Total $93.50
Sub Total $85.00

Pattern I gave :
(?<=Total)(.*)
Output I’m getting:

But I want to fetch only TOTAL value.

Any help would be appreciated:-)

Total $93.50
Sub Total $85.00

@Vaishnav_Tej

Please try this

(?<=^Total.*)\d+.\d+

cheers

Hi,

Can you try the following pattern?

(?<=(?<!Sub\s*)Total\s*)\$\d+

OR

(?<=(?<!Sub\s*)Total\s*\$)\d+

This expression is not extracting any of the values.
It just started execution and ended.

@Yoichi

(?<=(?<!Sub\s*)Total\s*\$)\d+

Hello sir,

This expression is not fetching decimal values.

Hi,

Sorry, how about the following?

(?<=(?<!Sub\s*)Total\s*)\$[.,\d]+

OR

(?<=(?<!Sub\s*)Total\s*\$)[.,\d]+

@Yoichi

(?<=(?<!Sub\s*)Total\s*)\$[.,\d]+

Thank you sir. It’s working perfectly.
Could you please share any link where I can learn regex.

Please include like this

System.Text.RegularExpressions.Regex.Matches(str,"(?<=^Total.*)\d+\.\d+",RegexOptions.Multiline)(0)

Actually I’m using Matches activity and inside pattern property I’m passing the expression.
Thanks for your response:-)
