Hi
Welcome to UiPath forum
U can use this expression in a assign activity like this to get all the matches
date_matches = System.Text.RegularExpressions.Regex.Matches(“input string”, “\d{1,2}.\d{1,2}.\d{4}”)
If u want them as array then u can use this
arr_matches = date_matches.Select(function(x) x.value).ToArray
If u want them as one string with a conman between each date value
stroutput = String.Join(“,”,date_matches.Select(function(x) x.value).ToArray)
To know more about Regex refer this post
Hope this helps
Cheers @Pradeep_Kalyan
