Document Understanding- Regex Based Extractor

Dear Community,

I am new to the document understanding and was following the tutorial in the uipath academy to build the workflow.

I try to use the regex based extractor to extract the following sample details for three scenario:
Sample 1 Field Ticket Ref Number 1012930.100

Sample 2 Field Ticket Ref No:XJ19-JI20

Sample 3 Field Ticket Ref No- ODJC.10J9

i have used the regex builder to extract the detail but i not sure how to build a better expression so that it can read all these three data.

The result that i would like to have for the above three sample data are as follow:



May i know if anyone know how to fix this or experienced before in doing the expression?

Many thanks again

How about the following regex give it a try

(?<=Field Ticket Ref Number.)(\S+)|(?<=Field Ticket Ref No.)(\S+)|(?<=Field Ticket Ref No.\s)(\S+)
