split a string from a sequence, with regex

Question

I need a regular expression that matches letters and digits, but doesn't match the sequence "00".

e.g. "hello00world00number001" should match: "hello", "world", "number" and "1".

I tested without success:

(?:[\w](?<!00))+

Edit: "hello000world0000number000001" must be separated into: "hello0" "world" "number0" and "1"

Answer 1

Input string: hello000world0000number00000100test00test20

Split

1. Splitting by 00 alone will generate empty matches if a series like 0000 is encountered:
   Output: hello/0world//number//01/test/test20

2. To work around this let's enclose 2 zeroes in a group:
   RegEx: (00)+ - last uneven 0 in the series goes to the next match - live demo
   Output: hello/0world/number/01/test/test20

3. Use a negative lookahead:
   RegEx: (00)+(?!0) - keep the first 0 in an uneven series in the first match - live demo
   Output: hello0/world/number0/1/test/test20

Match

1. incorrect result for 00 only
2. /([a-z0-9]+?)(?:(?:00)+|$)/gi - live demo
3. /([a-z0-9]+?)(?:(?:00)+(?!0)|$)/gi - live demo

Answer 2

str = "hello00world00number001"
str.split("00")

Why would this not work
