如何在AS3中使用RegularExpressions獲取圖像的源代碼？

Question

我只想寫一個合適的正則表達式來從給定的html文本中獲取圖像的來源。

//HTML TEXT: <img src="angry.gif" alt="Angry face" /> 

var regEx = //regex Here 

var source:Object = regEx.exec(htmlText); 

Answer 1

var regex:RegEx = /src="(.*?)"/i; 
var source:String = regex.exec(htmlText)[1]; 

Answer 2

var str:String="Content <img src='imagePath01.jpg' width='88' height='88'/> content content content <img src='imagePath01.jpg' width='88' height='88'/>"; 
     var imgRegExp:RegExp = /<img[^>]+>/g;//Get (add 'g' end regex) all img in content; 
     var imgArr:Array = str.match(imgRegExp); 
      for(var i:uint=0;i<imgArr.length;i++){ 
       trace(imgArr[i]); 
       //Get src from img; 
       var imgXML:XML = XML(imgArr[i]); 
       trace("src: "+imgXML.@src); 
      }
