现在我要获取里面的returnCode 和returnMessage里面的内容

	var xmlstr='ZZSDZFPEI.DYCOMCS.U.EC.INTRA4101029999992511234562019-11-08 10:30:36111ADBHB201910101000036510-200116Kej5p6Q6L6T5YWl5oql5paH5pWw5o2u5Y+R55Sf5byC5bi477yM6K+35pu05q2j5ZCO6YeN5paw5Lyg5YWl000PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz48UkVTUE9OU0VfQ09NTU9OX0RZQ09NQ1MgY2xhc3M9IlJFU1BPTlNFX0NPTU1PTl8gRFlDT01DUyI+PERZWFhTIC8+PC9SRVNQT05TRV9DT01NT05fRFlDT01D"';


    var pattern=/(.*)<\/returnCode>/i


    var code=pattern.exec(xmlstr);

    console.log(code[1]);


    var pattern1=/(.*)<\/returnMessage>/i

    var msg=pattern1.exec(xmlstr);

     console.log(msg[1]);

最后打印出来的结果如下：
