  I'm afraid I don't know this language (it comes from Pearl) but would like to use it to do a
  simple task and I don't have time to learn it.
  

  
  Could anyone tell me what's the regular expression to find the tag where the
  tag is defined as starting with [* and ending with *]
  

  
  e.g. [address]
  

  
  Thanks for any help.
  

  
  BTW - I've written the C# code so I don't need any help with that.

  I'm using :
  
  string tagFormat = "(\\[\\*\\w+\\*\\])";
  regex = new Regex( tagFormat );
  
  .....
  
  MatchCollection tags = regex.Matches( line );
  
  No matches are found.
  
  Any ideas?
  
  Thanks

  When you need to escape several characters, I'd suggest putting an "@" symbol before your string.  This tells the compiler to treat the entire string as literal, e.g. string tagFormat = @"(\[\*w+\*\])";.  This makes your string much easier to read.
