使用Pentaho解析XML数据

我有以下xml数据。我需要“additionalList”下的数据直接作为属性。但是我无法使用get XML data步骤来完成它。

<?xml version="1.0"?>
<List>
<Local>
<name>XXUT</name>
<age>38</age>
<additionalList>
    <Info>
    <Key>NameID</Key>
    <Value>321</Value>
    </Info>
    <Info>
    <Key>uOiD</Key>
    <Value>21</Value>
    </Info>
    <Info>
    <Key>NameArrayKey</Key>
    <Value>(5,7,9,9)</Value>
    </Info>
</additionalList>
</Local>
</List>

您的xml错误，您正在使用Key关闭第一个additionalInfoKey标记。应该是这样的：

<?xml version="1.0"?>
<List>
<Local>
<name>XXUT</name>
<age>38</age>
<additionalList>
  <Info>
  <Key>NameID</Key>
  <Value>321</Value>
  </Info>
  <Info>
  <Key>NameArrayKey</Key>
  <Value>(5,7,9,9)</Value>
  </Info>
</additionalList>
</Local>
</List>
