The text portion that contains alphanumeric characters (with punctuation removed) is returned and delimited by the first space character. If the parse-spec value does not return an alphanumeric text value, then the match specification is not matched.
The following examples show target strings, parse expressions, and return values:
| Target String | Parse expression | Return value |
|---|---|---|
| A B test123 | $alpha (3) | test123 |
| Test ABC123 value | $alnum ($2) | ABC123 |
| Test DEF456 value | $alnum (test *) | DEF456 |
| Test 009Strval999 value | $alnum (test *) | 009Strval999 |
| Test A1B1C1 | $alnum ($2) | A1B1C1 |
| This is a test V1:V2:V3 | $alnum (test *) | V1V2V3 |
| Test string 12345 | $alnum ($3) | 12345 |
| Test string AAA | $alnum ($4) | No match Explanation: There is no fourth word in the string. |
| Test String999 value | $alnum (xxx: *) | No match Explanation: There is no match for xxx: * in the target string. |
