Regex grab value for identifier

[SorenB (Søren)]

Hello

I am looking for a regex expression that will extract the desired value for a specific key, under a specific identifier.
The keys could move.

Example:

• Identifier: PersonDetails
• ValueForKey: lastname

Should give me the result “Doe”.

"elements":[
{
"identifier": "JobDetails",
"id": "asda892-241sad2-214sfs",
"values": {
"work address": "Random Road 2",
"city": "Random City",
"firstname": "Bob",
"lastname": "Johnsen"
}
}
{
"identifier": "PersonDetails",
"id": "sd89asd-gasg89-gasdf23",
"values": {
"firstname": "John",
"lastname": "Doe",
"age": 39
}
}
]

Regards
Soren

@SorenB

System.Text.RegularExpressions.Regex.Matches(Input,"((?<=""identifier"":\s+"")\w+)").Last.ToString

System.Text.RegularExpressions.Regex.Matches(Input,"((?<=""lastname"":\s+"")\w+)").Last.ToString

What if the same key could be for more that one identifier.
I have updated the example.

I want the regex to find my desired “identifier” and then zoom to the “values” to search for the desired key inside those.

String looks like JSON, so we can process with JSON approaches

we suggested above to base line on JSON. However a regex pattern could like this

and can also be finetuned

Hi @SorenB

Please find the below solution

1. Use assign activity to find the identifier = PersonalDetails for rest of other details

strLastName = System.Text.RegularExpressions.Regex.Match(strInput, """identifier"":\s*""PersonDetails""[^{]*\{[^}]*""lastname"":\s*""([^""]+)").Value.ToString.Trim

2. User assign acitivity to get the last name using the regex

strLastName = System.Text.RegularExpressions.Regex.Match(strLastName, "(?<=""lastname"":\s)(.*)").Value.ToString.Replace("""", "")

Output:
