Scenario:
- There is an incoming claim (or user attribute) that is being sent to a relying party
- When the claim is sent, the value must not exceed a certain character limit
- Data that-r2">
Scenario:
Example:
Transformation Claim:
c:[Type == http://contoso.com/claims/streetfull]
=> Issue (Type = http://contoso.com/claims/street,
|
Explanation:
We look for any incoming http://contoso.com/claims/streetfull claims. For those we perform an advanced RegExReplace().
Function Format: RegExReplace(string, match syntax, replace syntax)
String: c.Value
The string, is the value of a http://contoso.com/claims/streetful claim
Match Syntax:
(?<start>^.{1,50}).+$
The match syntax is broken into two major sections. The first section,
(?<start>^.{1,50}) , looks for the first 50 characters, and labels it as
<start>. The second section,
.+$ , matches everything after the first section. This is important, as we need to match everything in order to make the replacement work as needed.
Replace Syntax: ${start}
The match syntax, ${start} , represents the first 50 characters.
Effectively, we have isolated the first 50 characters into a variable, matched the entire string, then replaced the entire string with the variable.
