Groovy 脚本 - 员工报告结构 - 循环 XML 以找到所需的领导者

Question

我有两个 xml 使用 <multimap> 节点组合在一起。第一个数据源发送员工和经理 ID 信息（节点），第二个数据源发送所有领导者 ID 信息（节点中仅列出领导者 ID，领导者可以是经理的经理或直接经理或 2-up/3-up ）它们都组合在<multimap> 标签。

我想遍历 <multimap1> 节点的 <PerPerson>，检查经理 ID，直到在中找到领导者 ID，一旦找到领导者 ID，就在员工记录（节点）中添加一个节点。

请帮忙！

XML 文件:

所需结果：在上面的员工和经理数据中，在标签内进行迭代，直到经理 ID 是 rfc / get approvers 列表中的领导者 ID 之一。一旦找到，在标签内添加带有 ID 的领导者 ID 标签

我试过的代码

    map = message.getProperties();
   def body = message.getBody(java.lang.String) as String;
def messageLog = messageLogFactory.getMessageLog(message);

 def xml = new XmlParser().parseText(body)

    def ns = new groovy.xml.Namespace('http://sap.com/xi/XI/SplitAndMerge')
def rfcNs = new groovy.xml.Namespace('urn:sap-com:document:sap:rfc:functions')
   
//for fast search let map PERNR value to a node that contains it, like internal table
def leaderMap = xml[ns.Message1][0][rfcNs.get("ZHR_GET_AWARD_LEADERS.Response")][0].children().collectEntries{ [it.LEADER_LIST.item.text().replaceFirst("^0+(?!$)", ""), it] }

  
//itearte msg1 -> find entry in leaderMap -> add node
xml[ns.Message2][0].PerPerson[0].each{p->
def emp = p.PerPerson[0]
def leader = leaderMap[p.PerPerson.userAccountNav.UserAccount.user.User.manager.User.mgrEmpId.text()]
if(leader)
{
 //  def counter = counter + 1
   p.PerPerson.appendNode('leader', null, leader.text() )
}

}

错误：代码未根据匹配找到的经理 ID 过滤领导 ID

Answer 1

我在您的代码中发现了一些错误：

NodeList 没有 appendNode 这就是发生错误的原因
p 已经是 PerPerson 节点之一，可能会导致代码混乱
ZHR_GET_AWARD_LEADERS.Response 标签在提供的 xml 中不存在，所以我改为 ZZH_LEADER_WF_GET_APPROVERS.Response

我做的是：

实例化 'Node' 使用 new Node(p, 'leader', leader.text()) 从而在 xml
删除了对 children() 的调用并在收集到 leaderMap

collect { it }

删除了闭环内的 PerPerson 个调用
创建了查找员工领导的算法

groovyide.com/cpi代码

import com.sap.gateway.ip.core.customdev.util.Message;
import java.util.HashMap;
import groovy.xml.XmlUtil;

def Message processData(Message message) {
    def body = message.getBody(java.lang.String) as String
    def xml = new XmlParser().parseText(body)
    def ns = new groovy.xml.Namespace('http://sap.com/xi/XI/SplitAndMerge')
    def rfcNs = new groovy.xml.Namespace('urn:sap-com:document:sap:rfc:functions')

    // I HAD TO CHANGE THE LINE BELOW BECAUSE THE XML DIDN't HAVE "ZHR_GET_AWARD_LEADERS.Response"
    //for fast search let map PERNR value to a node that contains it, like internal table
    def leaderMap = xml[ns.Message2][0][rfcNs.get("ZZH_LEADER_WF_GET_APPROVERS.Response")][0]\
                        .collect { it }.collectEntries { [it.text().replaceFirst("^0+(?!$)", ""), it] }

    // All employee manager's, including the managers themselves
    def upManagers = xml[ns.Message1][0].PerPerson[0].collect { it }.collectEntries { p ->
        [p.empId.text(), p.userAccountNav.UserAccount.user.User.manager.User.mgrEmpId.text()]
    }

    // itearte msg1 -> find entry in leaderMap -> add node
    xml[ns.Message1][0].PerPerson[0].each { p ->
        def manager = p.userAccountNav.UserAccount.user.User.manager.User.mgrEmpId.text()
        def leader = leaderMap[manager]
        while (!leader && manager) {
            manager = upManagers[manager]
            leader = leaderMap[manager]
        }
        def node = new Node(p, 'leader', leader.text())
    }
    message.setBody(XmlUtil.serialize(xml[ns.Message1][0].PerPerson[0]))
    return message
