RegexpExtract
Returns the substring that matches a regular expression within a string.
Usage
RegexpExtract(string, substring, [position])
string (required): The string to search
substring (required): The substring to extract with.
position (optional): The index of the match to return.
When the regular expression contains a slash, quotation or other special character, you will need to use a backslash (\) to escape the special character. Regexp can vary based on the databases. Check the documentation of the database you use to find the correct syntax.
Example
RegexpExtract([Address], "[0-9]+")
- Extracts the first match of numeric characters in the string. No position is specified so position defaults to 1.
Output:
RegexpExtract([Address], "[0-9]+", 2)
- Extracts the second match of numeric characters in the string.
RegexpExtract([Address], "\\s*([a-zA-Z]+)", 2)
- Extracts the second match of alphabetical characters in the string.
Output:
RegexpExtract([Date], "(\\d{2})", 2)
- Extracts the second match, day of date, of the 2-digit character group in the date.
