A regular expression (regex or regexp) is a sequence of characters that define a search pattern. They can be very helpful for filtering out segments in the TXLF Editor or for find/replace operations. Check out this article for a more detailed explanation of the history of regular expressions and how they work.
Below are a few examples of useful regex. Make sure to tick the regex box accordingly:
Hide all number-only segments
Use the following regex in the segment filtering bar:
^(([0-9][^\n]*[^0-9])|([^0-9][^\n]*[0-9])|([^0-9]?[^\n]*[^0-9]))$
This regex will also hide numbers with punctuation (decimals, etc.)
Show only number-only segments
Use the following regex in the segment filtering bar:
^(?:(?:-|–|(?:(?:\$|€|£)(?:\h)?))?(?:\d{1,3})(?:\h|,|\.|(?:(?:\h)?(?:%|\$|€|£)))?)+$
If you have numbers like 8,675,309.00 that need to be replaced with 8.675.309,00, you can copy all sources to target with the filter applied, then apply a 3-step find and replace: 1. Find . and replace with DUMMY 2. Find , and replace with . 3. Find DUMMY and replace with ,
