Question

replaceAll string function for replacing special characters

0

Hi, In the documentation I can see that replaceAll function is used for replacing numbers from 0 to 9. However, I need it to replace multiple characters ( if found ) from a given string. The characters that I need replaced are : \, : , / , FW: , RE: , ? , | , * , < , > , & How do I write these multiple characters in the way the function will understand to search for all of them in the string? Original example from Mendix docs: replaceAll('this is a string with no numbers thrown in', '([0-9])', 'NUMBER') Thanks, Razvan

You can use a regex here. So [/|*<>] would search on any of these characters.

If you like, you can use the RegexReplaceAll java action and replace the Needle Regex input with the characters you would like to replace.

Hello Razvan Cojocaru,

Please use regex '([\\/:?|*<>&]|FW:|RE:)' as shown in below example to remove characters : \, : , / , FW: , RE: , ? , | , * , < , > , &

Example

replaceAll('FW: Some | example \\ text with / characters to RE: replace?', '([\\/:?|*<>&]|FW:|RE:)', '')

Thanks
