Problem using regexp - syntax error on [

Else, I think you could use the wildcards (? or [chars]) available in TCL's string match command for a lighter weight comparison:

 

 

 

string match pattern string

 

See if pattern matches string; return 1 if it does, 0 if it doesn't. Matching is done in a fashion similar to that used by the C-shell. For the two strings to match, their contents must be identical except that the following special sequences may appear in pattern:

 

 

*

 

Matches any sequence of characters in string, including a null string.

 

 

?

 

Matches any single character in string.

 

 

[chars]

 

Matches any character in the set given by chars. If a sequence of the form x-y appears in chars, then any character between x and y, inclusive, will match.

 

 

\x

 

Matches the single character x. This provides a way of avoiding the special interpretation of the characters *?[]\ in pattern.
