我需要输出以下信息

<EmpLDU>
        <Row>
            <Emp_id>325132 </Emp_id>
            <Date_from_ec>20170814</Date_from_ec>
            <Date_to_ec>20170816</Date_to_ec>
        </Row>
        <Row>
            <Emp_id>1 </Emp_id>
            <Date_from_ec>20170720</Date_from_ec>
            <Date_to_ec>20170720</Date_to_ec>
        </Row></EmpLDU>

当参考消息2＆gt;更新字段Date_from_ec时。 PayPeriod节点（当前月份存在payCheckIssueDate的节点）那么如果payPeriodBeginDate比Date_from_ec更好，那么

需要使用payPeriodBeginDate更新Date_from_ec的值，否则保留现有值。

类似地参考消息2＆gt;更新字段Date_from_ec。 PayPeriod节点（当前月份存在payCheckIssueDate的节点）然后，如果payPeriodBeginDate小于Date_to_ec那么

需要使用payPeriodEndDate更新Date_to_ec的值，否则保留现有值。

我开发了以下代码，但没有开心：
