紧急求救,在线等:求正则表达式

[sdav]

String HtmlBody = "<a>$abc123$</a>sdasfsadfsdfsadfasdf<a>sdav</a>$diav$";
//我想匹配出两个$符号之间的内容.如上这个字符串,应该匹配出$abc123$和$diav$两项.
String RegexStr = "\$.*\$";
Pattern pattern = Pattern.compile(RegexStr);
Matcher matcher = pattern.matcher(HtmlBody);
boolean IsMatcher= matcher.matches();
if(IsMatcher)
{
System.out.println("匹配结果:" + IsMatcher);
System.out.println("匹配数量:" + matcher.groupCount());
}
else
{
System.out.println("没有匹配的项!");
}

各位老大帮帮忙,这个正则表达式该怎么写啊?

各位老大,是Java程序哦.俺Java新学,各位请帮帮忙.

String HtmlBody = "<a>$abc123$</a>sdasfsadfsdfsadfasdf<a>sdav</a>$diav$";
      //我想匹配出两个$符号之间的内容.如上这个字符串,应该匹配出$abc123$和$diav$两项.
      Pattern pattern = Pattern.compile("\\$\\w+\\$");
      Matcher matcher = pattern.matcher(HtmlBody);
 
      while (matcher.find()) {
        System.out.println(matcher.group());
     }

String HtmlBody = "<a>$abc123$</a><a>$dav#年龄#18#男$</a>sdasfsadfsdfsadfasdf<a>sdav</a>$diav$";
//我想匹配出两个$符号之间的内容.如上这个字符串,应该匹配出$abc123$，$diav$，$dav#年龄#18#男$三项.
Pattern pattern = Pattern.compile("\\$\\w+\\$");
Matcher matcher = pattern.matcher(HtmlBody);
while (matcher.find()) {
System.out.println(matcher.group());
}
//如上这样写的话，$abc123$，$diav$可以匹配出来，可是$dav#年龄#18#男$就匹配不出来了，为什么呢？

Pattern pattern = Pattern.compile("\\$[^\\$]+\\$");

那就改成这样，前面你没有#数据的

呵呵,谢谢你,我自己弄出来了,呵呵

Pattern pattern = Pattern.compile("\\$\\S+\\$");
