Answer 1

希望没错...
<SCRIPT LANGUAGE="JavaScript" defer>
<!--
var imgStr = '<img src="image/icons/cloudday_small.gif" width="20" height="20">dfsdf<img src="image/icons/cloudday_454.gif" width="20" height="20">';
imgStr.match(/src=\"([^\"]*)/gi);
alert(RegExp.$1);

试试这样？String s = "<img src=\"image/icons/cloudday_small.gif\" width=\"20\"" +
"height=\"20\">dfsdf<img src=\"image/icons/cloudday_454.gif\"" +
"width=\"20\" height=\"20\">\"";
Pattern pattern = Pattern.compile("<img\\s+src=\\\"([^\"]+)\".*");
Matcher match = pattern.matcher(s);
String url = null;
if(match.matches()) {
url = match.group(1);
}

String s = "<img src=\"image/icons/cloudday_small.gif\" width=\"20\" height=\"20\">dfsdf<img src=\"image/icons/cloudday_454.gif\" width=\"20\" height=\"20\">";
Matcher m = Pattern.compile("src=\"?(.*?)(\"|>|\\s+)").matcher(s);
while(m.find())
{
System.out.println(m.group(1));
}
