Version 20.0.7488

The arc:match keyword is similar to the arc:equals keyword; however, it permits complex matching rules.


  • pattern: The pattern to match.
  • type: The type of matches to find. The default value is “exact”, which requires an exact match of the value. In this case arc:match is identical to arc:equals. Other supported types are “regex”, for regular expression matching, and “glob”, which supports a simple expression model similar to the one used in file-name patterns, for example, *.txt.

    The .NET edition of the application uses the .NET Framework version of regular expression matching. The Java edition uses Java regular expression constructs.

  • value: The value to match.
