title: Javascript - Regular Expressions - Using Not operator
body: <p>I know this is probably quite straightforward but cannot seem to find an example of what I'm trying to do.</p>
  
  <p>Matching from start of a string, i want to match building numbers.</p>
  
  <p>i.e.</p>
  
  <p>60 would match 60A and 60 but not 6000</p>
  
  <p>likewise</p>
  
  <p>1 would match 1 and 1ABC but not 11</p>
  
  <p><code>/^1[^\0-9]*</code></p>
  
  <p>is like what i need, matching 1 and any non numeric value any number of times. (granted this is from expresso - (.net) but it doesn't work in there.</p>
  
  <p>can anybody point me in the right direction?</p>
  
  <p>thanks,</p>
  
  <p>Sam</p>
