Remove bytes from string

[rk1960in]

I have a string with "\00\00\00\00\A6\00". Is there a build in function to remove "\00" or should the approach be using regular expressions? Trim white space function does not remove the bytes.

I'm a little surprised the native Remove White space doesn't work. I also tried the OpenG remove white space and it didn't remove it. There's alot of over head but I think a simple solution would be to use the String to Byte Array, then use the OpenG Filter Array to remove any zeros, then use the byte array to string.

EDIT: Sorry thought of an easier solution. Use the Search and Replace string, where you search for the 00 and replace with nothing. There is a boolean input to remove all, that needs to be set to true.

The NULL character isn't white space, much less a printable character, which is why neither of those VIs did (or should) remove it.

Search and Replace is a good way to do it, or if you know your data will always have 4 NULL characters prepended, you could use String Subset, which may garner a performance gain.

In a twist of fate, I was just bitten by this when I was pulling in a null-terminated string from a Windows API call.

These can probably be combined into a single node using alternation, so your regex would be "^[\00]*|[\00]*$".

Fast Trim rermoves null chars (non-printable) and not just whitespace.
