Regular Expressions Considerations

Consider the following situations when using Regular Expressions in CA SOI:

Regular Expressions in CA SOI act as a find, not as a match.

A find searches for the pattern across the strings, including the substrings.

A match searches for the pattern in the strings only.

Example:

With the following strings: "cart" and "artistic":

• A find for the "art" pattern finds "art" in the substrings of both the "cart" and "artistic" strings.
• A match for the "art" pattern does not match in "cart" or "artistic" strings because a match does not search the substrings.

To perform a match in CA SOI, enclose the pattern with "^" and "$", such as "^art$". You can use the Regex Tester to verify your expressions before implementing them.
