Regular Expression Functions

Overview

This Plug-in exposes Java Regular Expression string manipulation capabilities as Appian Functions. Very useful for validation rules and data manipulation on interactive SAIL forms.

Key Features & Functionality

Datatypes provided:

RegexMatch - has a string field representing the string found, a starting index for the string in the haystack and an ending index for the string in the haystack

Regex Flags supported:

i - case insensitive
g - find all matches
m - multiline search
s - treats the entire string as a single line
u - unicode aware search
x - ignores comments starting with '#' and white spaces
d - enables unix line mode

Functions provided:

regexSearch - Searches for the selected pattern with the specified regex options and returns a list of RegexMatch Datatypes, accepts all regex flags.
regexArraySearchIndexOfFirstMatch - Searches an array for a match and returns the first index of match found
regexMatch - Indicates whether the regular expression finds a match in the input string, accepts all regex flags.
regexInsertMatchMarkers - Finds the match or matches and surrounds them with starting and ending markers, accepts all regex flags.
regexFirstMatch - Returns the first match of the regular expression within the input string, accepts all regex flags except 'g'.
regexAllMatches - Returns all matches of the regular expression within the input string, accepts all regex flags.
regexReplaceAll - Replaces all matches of the regular expression within the input string

Good day! Just starting to learn your product, but how can I get this Java REGEX into your regex function to return a result?

List<String> ssns = new ArrayList<String>();
       
//Valid SSNs
ssns.add("123-45-6789");  
ssns.add("856-45-6789");  
 
//Invalid SSNs
ssns.add("000-45-6789");  
ssns.add("666-45-6789");  
ssns.add("901-45-6789");  
ssns.add("85-345-6789"); 
ssns.add("856-453-6789"); 
ssns.add("856-45-67891"); 
ssns.add("856-456789"); 
 
String regex = "^(?!000|666)[0-8][0-9]{2}-(?!00)[0-9]{2}-(?!0000)[0-9]{4}$";
 
Pattern pattern = Pattern.compile(regex);
 
for (String number : ssns)
{
    Matcher matcher = pattern.matcher(number);
    System.out.println(matcher.matches());
}
 
Output:
 
true
true
 
false
false
false
false
false
false
false

Hello!

For this you'd probably just want to use the regexmatch function like this:

a!localVariables(
  local!ssns: {
    /*Valid SSNs*/
    "123-45-6789",
    "856-45-6789",
    /*Invalid SSNs*/
    "000-45-6789",
    "666-45-6789",
    "901-45-6789",
    "85-345-6789",
    "856-453-6789",
    "856-45-67891",
    "856-456789"
  },
  a!forEach(
    items: local!ssns,
    expression: regexmatch(
      "^(?!000|666)[0-8][0-9]{2}-(?!00)[0-9]{2}-(?!0000)[0-9]{4}$",
      fv!item
    )
  )
)

Output: 

true(Boolean)
true(Boolean)
false(Boolean)
false(Boolean)
false(Boolean)
false(Boolean)
false(Boolean)
false(Boolean)
false(Boolean)
