- The string expressions can contain any of the objects specified in the notes for StringExpression.
- StringReplace goes through a string, testing substrings that start at each successive character position. On each substring, it tries in turn each of the transformation rules you have specified. If any of the rules apply, it replaces the substring, then continues to go through the string, starting at the character position after the end of the substring.
- If the in the replacements do not evaluate to strings, StringReplace will yield a StringExpression rather than an ordinary string.
- In replacements of the form , the are not evaluated until each time they are used.
- Setting the option IgnoreCase->True makes StringReplace treat lowercase and uppercase letters as equivalent.
