unexpected element (uri:"", local:"prescDrug"). Expected elements 错误

soap协议访问webservice，如果入参中有list，需如下写入参格式

 "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
				+ "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" "
				+ "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">"
				+ "<soapenv:Body>"
				+ "<ns1:postPresc soapenv:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\" xmlns:ns1=\"http://service.webService.com\">"
				+ "<prescInfos>"
				+ "<hospId>1001</hospId>"
				+ "<hospName>杭州第一医院</hospName>"
				+ "<patientCard>A12345678</patientCard>"
				+ "<patientName>1000</patientName>"
				+ "<patientPhone>1000</patientPhone>"
				+ "<postType>2</postType>"
				+ "<prescCode>NO123412</prescCode>"
				+ <span style="color:#6633ff;">"<prescDrugs>"</span>
				+ "<drugCode>1000</drugCode>"
				+ "<quantity>1000</quantity>"
				+ "<remark>最好别吃</remark>"
				+ <span style="color:#6600cc;">"</prescDrugs>"</span>
				+ "</prescInfos>"
				+ "</ns1:postPresc>"
				+ "</soapenv:Body>" + "</soapenv:Envelope>"

实体如下：

public class PrescInfo {
int hospId;// 医院编号
String hospName;// 医院名称
String prescCode;// 医院处方编号
String patientCard;// 患者卡号
String patientName;// 患者姓名
String patientPhone;// 患者手机
int postType;// 传送类型，1新增，2更新
List<PrescDrug> prescDrugs;// 处方药品信息列表 <<<<<<<这里参数是list
