如果正则表达式不包含特定单词，如何匹配它？

Question

I want to write a regex in Python or JavaScript to match if the given string does not JUST contain the given word (eg "any").

For example:

any : does not match
AnY : does not match
anyday : match
any day : match
blabla : match

Answer 1

If you also need words other that starting with "any" you can use a negative lookahead

^(?!any$).*$

This will match anything besides "any".

Answer 2

It is probably more efficient to not use a regex, this works as well:

def noAny(i):
    i = i.lower().replace('any', '')
    return len(i) > 0

Answer 3

Something like this:

/(any)(.+)/i

Answer 4

any.+

..and some text to make the 30char threshold

Answer 5

Use string.match(regexp) method in javascript for this purpose. See the code below:

<script type="text/javascript">
      var str="source string contains YourWord"; 
      var patt1=/YourWord/gi; // replace YourWord within this regex with the word you want to check.  
      if(str.match(patt1))
      {
         //This means there is "YourWord" in the source string str. Do the required logic accordingly.
      }
      else
      {
          // no match
      }
</script>

Hope this helps...
