Use RegEx in variables

In fields that offer variables, you can use regular expressions too (RegEx). It allows complex search patterns with special strings. pdfToolbox 8.0 has improved the integration of RegEx.

Where can RegEx be used as input values

If an input field alles regular expressions can be recognized by the RegEx icon next to the pull down menu. Regular expressions can be used in some Checks or Fixups.

The pull down menu has four states:

  • Equal to
  • Unequal to
  • Matches with RegEx
  • Does not match with RegEx

By clicking on the green "RegEx" icon, an assistance to the practical possibilities of the regular expression is shown.
