Find & Replace specific character in a String

8 posts in this topic

I have done a bit of searching and am not sure what function I need to use for this. For Example, I have a string named:

Test/User

I want to do a find and replace by searching for the "/" in the string and replacing it with an "_". I would like to do the same for other illegal characters as well. The string will be used in a filename and fails to save if there are illegal characters. The other way to fix this would be to not allow illegal characters to be entered to begin with, but the users will be copying and pasting stuff, so it's easier in this case just to automatically search for specific characters in the string and replace them with the underscore. Any assistance is appreciated.

hogfan,

I think this covers all the characters not permitted in file names:

$sText = 'Test/User\Test:User*Test?User"Test<User>Test|User'

$sNewText = StringRegExpReplace($sText, '\\|/|:|\*|\?|\"|\<|\>|\|', "_")

MsgBox(0, "Amended Text", $sNewText)

Please ask if you have any questions. :)

Yes but note that you don't need to escape non-special characters :P

$string = "my/file? *<and\one|two:three>"
$string = StringRegExpReplace($string, '(/|\?|<|>|\\|:|\*|\||")', "_")
msgbox(0,"", $string)

mikell,

I have always been a "belt and braces" sort of coder when it comes to Regexes! :D

Maybe a character class is quicker.

Melba -

Thanks for the assistance.

StringRegExpReplace was exactly what I needed.
