A pattern that matches all except starting with a word

Question

How can I set a regex pattern which matches all words but the strings which starts with

1. /word
2. /word/
3. /word/ following by anything else.

I think the pattern starts with \A but I don'0t know how to tell that should not follow a word

Thanks

Answer 1

Use this kind of negate regex and replace word by your word.

^((?!word).)*$

Answer 2

You can use the regex:

^(?!\\/word).*$

Answer 3

Take a look at the lookaround feature offered by regular expressions. Also, a similar thread. Also, posting your question in terms of a concrete sample problem might help you get a few working sample snippets.

Answer 4

Perhaps using a string comparison will be clearer and faster.

if (text.startsWith("word")) {
   // text is OK
} else {
   // not OK
}
