根据employment_information节点的出现情况创建多个ComponentEmployee节点,保持父节点不变

Input:
queryCompoundEmployeeResponse
CompoundEmployee
person
personal_information
email_information
employment_information
employment_information
CompoundEmployee
person
personal_information
email_information
employment_information

Output:

queryCompoundEmployeeResponse
CompoundEmployee
person
personal_information
email_information
employment_information
CompoundEmployee
person
personal_information
email_information
employment_information
CompoundEmployee
person
personal_information
email_information
employment_information

        </person>
    </CompoundEmployee>
</queryCompoundEmployeeResponse>

问题:输出xml包含值为Node类型的节点personal_information、email_information和employment_information,需要像输入示例中那样转换为xml。

<personal_information>
personal_information[attributes={}; value=[first_name[attributes={}; value=[Test01]], gender[attributes={}; value=[M]], last_name[attributes={}; value=[test01]]]]
</personal_information>

这需要在输出中采用以下格式:

 <personal_information>
  <first_name>Test01</first_name>
  <gender>M</gender>
  <last_name>test01</last_name>
  </personal_information>

你能纠正我在这里做错了什么吗? 注意:该模式非常大,包含多个字段。我刚刚做了一个简单的模式。代码需要动态生成该特定节点的所有字段/元素。

使用XmlSlurper

def root = new XmlSlurper().parseText(xml)

那么这个 mkp.yeld 应该工作

person{
    person_id_external(compoundEmployee.person.person_id_external)
    mkp.yield compoundEmployee.person.personal_information
    email_information(compoundEmployee.person.email_information)
    employment_information(employmentInfo)
}
