使用java drools

Question

我在表格中有以下数据 -

ID    ABC_23_02
--    --------
01    See your note and security instrument for information about 
      -what happens if you fail to make your payments,
      -what is a default on the loan.

现在，我希望在列中找到相同的值时触发规则。这是我的代码片段 -

rule "Rule - Success"
    when
        form: Form_ABC()
        $m: Map()
        $ID: Object() from $m["ID"]
        $x: Object() from $m["ABC_23_02"]
        Map(Utility.rtnString($x) == "See your note and security instrument for information about\n-what happens if you fail to make your payments,\n-what is a default on the loan.") 
    then
        Utility.helper(drools);
        if(!($ID.toString().equalsIgnoreCase("ID")))
        {
        form.setCD_23_02(Utility.rtnString($x));
        System.out.println("Rule - Pass\t\t" + $ID.toString() 
                                             + "\tField 1 is: " + $x.toString());
        }
end 

而且，这是我正在调用的Utility.rtnString（$ x）函数 -

public static String rtnString(Object Input)  {
            //String numOnly = Input.toString().replaceAll("[^\\w\\s\\.]","");
            String numOnly = Input.toString().replaceAll("[^\\w\\s\\.\n]","");
            return numOnly.toUpperCase();
        } 

但是，我无法使用上面的内容在列中查找字符串。你能否提出一个更好的方法来实现同样的目标。感谢。
