Question

我想获取具有重复元素的XML文档的XPath和值。

示例：

<Return>
  <ReturnData>
    <Person>
      <Name>Yohanna</Name>
    </Person>
    <Person>
      <Name>Jacoub</Name>
    </Person>
  </ReturnData>
</Return>

我想归还给我：

1. /Return/ReturnData/Person[1]/Name=Yohanna
2. /Return/ReturnData/Person[2]/Name=Jacoub

我以前有过不同的Java代码实现，但是从其他人那里得到了这个实现（@nazar_art）。但是当我从顶层检索Xpath和值时，所有值都返回为空/空。

外首循环：

Evaluate xpath expression: [/PayrollFormInfo/CompanyInfo/EmpSummary/SSN]
2015-08-24 16:10:19,646 : XPATH result is EMPTY, for next xpath [/PayrollFormInfo/CompanyInfo/EmpSummary/SSN]
Evaluate xpath expression: [/PayrollFormInfo/CompanyInfo/EmpSummary/IsStatutory]
2015-08-24 16:10:19,646 : XPATH result is EMPTY, for next xpath [/PayrollFormInfo/CompanyInfo/EmpSummary/IsStatutory]
Evaluate xpath expression: [/PayrollFormInfo/CompanyInfo/EmpSummary/HasPensionPlan]
2015-08-24 16:10:19,647 : XPATH result is EMPTY, for next xpath [/PayrollFormInfo/CompanyInfo/EmpSummary/HasPensionPlan]
Evaluate xpath expression: [/PayrollFormInfo/CompanyInfo/EmpSummary/EmployeeType]
2015-08-24 16:10:19,647 : XPATH result is EMPTY, for next xpath [/PayrollFormInfo/CompanyInfo/EmpSummary/EmployeeType]
Evaluate xpath expression: [/PayrollFormInfo/CompanyInfo/FederalReturnType]
2015-08-24 16:10:19,648 : XPATH result is EMPTY, for next xpath [/PayrollFormInfo/CompanyInfo/FederalReturnType]
Evaluate xpath expression: [/PayrollFormInfo/EmployeeInfo/EmployeeType]

第二次循环输出：

Here! []
Here! []
Here! []
Here! []
Here! []
Here! []
Here! []
Here! []
Here! []

我不明白出了什么问题？当元素明确具有值时，为什么它不能找到元素的值。

以下是正在评估的XML文件：
