When searching for objects by name, such as element names, event frame names, or attribute names (when associated with a template), you can use special characters:
|
Special character |
Purpose |
|---|---|
|
* |
Substitute any number of unspecified characters. |
|
? |
Substitute a single unspecified character. |
|
[xyz] |
Specify a set of characters (x, y, or z) to match. |
|
[!xyz] |
Specify a set of characters (x, y, or z) to preclude a match. |
|
\ |
Ignore the subsequent special character and interpret as its actual character. |
|
[first-last] |
Specify a range of characters (from first to last) to match. For example, a[a-c] matches aa, ab, or ac, but does not match ad or abc. |
