根据天数比较差异删除XML节点

Question

需求是比较日期，如果差异超过指定的天数，我们需要丢弃特定的 XML 节点以进行进一步处理。我已经为相同的内容编写了 groovy 脚本，以便在 SAP CPI 集成工具中使用相同的内容。不知道为什么它不起作用。 根据脚本，我预计第一个节点将被删除，因为 57 不大于 60。第二个节点 423 大于 60，因此我预计输出中会出现该节点。我没有收到任何错误，我在输出中得到相同的输入

任何帮助或建议将不胜感激。

参数：

interfaceLastRunTime = 2024-06-01T00:00:00
effDateDiff = 60
ManualRun= Yes
golive_date = 
Manual_Delta_LSRD = 2024-06-01T00:00:00
end_dt = 2024-07-31T00:00:00

Groovy 脚本：

    def payload = new XmlSlurper().parse(body);

    map = message.getProperties();
    def lsrd = map.get("interfaceLastRunTime");
    int effDateDiff = map.get("effDateDiff").toInteger();
    def manual_run = map.get("ManualRun");

    }
    lsrd = lsrd.substring(0, 19);
    SimpleDateFormat sdf = new SimpleDateFormat("ddMMyyyy");
    SimpleDateFormat sdtf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"); 

    payload.Row.each {r ->
       def pid = r.PID.text();
       def jobinfo_stdt = r.jobinfo_stdt.text()

           Date new_LSRD = sdtf.parse(lsrd); 
           
            int dateDiffInDays = new_LSRD - new_jobinfo_stdt;
            dateDiffInDays=dateDiffInDays.toInteger()+1

            }
       }
    }       
    message.setBody(XmlUtil.serialize(payload));
    return message;

我通过使用 XML 解析器而不是 XML slurper 解决了这个问题，并对脚本进行了一些修改：
