That means that, for an unanchored pattern, if a continued match fails, it is |
|
not possible to try again at a new starting point. All this facility is capable |
|
of doing is continuing with the previous match attempt. In the previous |
|
example, if the second set of data is "ug23" the result is no match, even |
|
though there would be a match for "aug23" if the entire string were given at |
|
once. Depending on the application, this may or may not be what you want. |
|
The only way to allow for starting again at the next character is to retain the |
|
matched part of the subject and try a new complete match. |
