关于正则表达式匹配问题

[zlp321002]

var PRODUCT_HASH=new Hash({"3627":{"bn":"G507779B886294-3","price":184.8,"mktprice":268.92,"store":73,"weight":"6000.000","mprice":{"9":177.41,"10":177.41,"13":180.6,"26":176.4,"1":184.8,"2":182.952,"3":181.104,"4":181.104,"5":179.256,"6":179.256,"7":177.408,"8":177.408},"spec_private_value_id":["14331943713"]}});
var PRODUCT_SPECV_ARR=[];
PRODUCT_HASH.each(function(v){
PRODUCT_SPECV_ARR.push(v['spec_private_value_id']);
});


我想匹配：”var PRODUCT_HASH=new Hash(“ 与 “);” 之间的json 字符，正则如何写呢

要求输出如下：

{"3627":{"bn":"G507779B886294-3","price":184.8,"mktprice":268.92,"store":73,"weight":"6000.000","mprice":{"9":177.41,"10":177.41,"13":180.6,"26":176.4,"1":184.8,"2":182.952,"3":181.104,"4":181.104,"5":179.256,"6":179.256,"7":177.408,"8":177.408},"spec_private_value_id":["14331943713"]}}

var sss = Regex.Match(s, @"\(([{\[].*?[}\]])\)");
Console.WriteLine(sss.Groups[1].Value);

{"3627":{"bn":"G507779B886294-3","price":184.8,"mktprice":268.92,"store":73,"weight":"6000.000","mprice":{"9":177.41,"10":177.41,"13":180.6,"26":176.4,"1":184.8,"2":182.952,"3":181.104,"4":181.104,"5":179.256,"6":179.256,"7":177.408,"8":177.408},"spec_private_value_id":["14331943713"]}}

@"(?<=Hash\().+?(?=\))"

[娃都会打酱油了]

()内可能出现()吗？ 如果不可能出现的话，简单的

@"var\s+PRODUCT_HASH=new\s+Hash\(([^()]*?)\)"

就可以，然后m.Groups[1]取值， 否则的话，就要用上平衡组了，平衡组怎么写查下就知道了，都一样的写法

[q107770540]

json会有嵌套现象，所以此处应该使用平衡组：

(?<=var PRODUCT_HASH=new Hash\()\{((?<o>\{)|(?<-o>)\}|[^{}]+)*(?(o)(?!))\}(?=\);)
