Regular Expressions

Regular Expressions can be used in various features in your Localize dashboard.

A number of features in your Localize dashboard allow you to enter a Regular Expression or "regex", including:

  1. Disable Localize by Page
  2. Disable Phrase Detection by Page
  3. Define Variables in Your Dynamic Phrases
  4. Block New Phrases by Pattern

Special Characters in Regular Expressions

Special Characters

Regular expressions use special characters (metacharacters) to denote which characters to match in the source content. You must be careful when adding words/phrases to this list so that they aren't interpreted differently than you expect them to be.

The special characters are:

  • backslash \
  • caret ^
  • dollar sign $
  • period or dot .
  • vertical bar or pipe symbol |
  • question mark ?
  • asterisk or star *
  • plus sign +
  • opening parenthesis (
  • closing parenthesis )
  • opening square bracket [
  • opening curly brace {

Escaping

Any special characters that can be used in regular expressions will need to be "escaped" if you want to match the literal character.

For example: If you want to exclude anything with .tif in the phrase, you would enter: \.tif

  • The backslash tells the parser to consider the "." as a literal character.
  • Without the backslash, the .tif would include any phrase that has at least one character before tif, e.g. any phrase with the word "identify", etc.
