Additional Information:

  • Conditions are always in the form: [<element>] <operator> <value>.
  • The value does not need to be in quotes if it consists of a single alphanumeric word or a number.
  • If the element name contains non-alphanumeric characters, enclose it in square brackets, e.g., [PARAM | color] = "blue".
  • Text values and regular expressions should be enclosed in straight quotes (" "), not curly quotes (“ ”).
  • We recommend always using square brackets so that we can suggest element names for you.
