Actionscript：检查字符串是否包含域或子域(Actionscript: check if string contains domain or subdomain)

 我需要知道字符串是否包含特定域 
 
 我有这样的数组 
 
private var validDomain:Array  =  new Array(
  "http://*.site1.com",
  "http://*.site2.com",
  "http://*.site3.com",
  );

private var isValidDomain:Boolean =  false; 
private var URL:string =  "http://mysub.site2.com";  
 
 现在我会检查我的字符串是否有效，所以我想是这样的： 
 
for each (var domain_ in validDomain){
      if(SOMEREGEX){
      isValidDomain=true;
      }
  }
 
 我把什么放在SOMEREGEX？！ 

I need to know if a string contains a specific domain
 
I have an array like this
 
private var validDomain:Array  =  new Array(
  "http://*.site1.com",
  "http://*.site2.com",
  "http://*.site3.com",
  );

private var isValidDomain:Boolean =  false; 
private var URL:string =  "http://mysub.site2.com";  
 
now i would check if my string is valid, so i think something like that:
 
for each (var domain_ in validDomain){
      if(SOMEREGEX){
      isValidDomain=true;
      }
  }
 
What i put in SOMEREGEX?!
