将XML转换为CSV不起作用

<?xml version="1.0"?>
<servstate>
<title>2018-06-11  12:00:01</title>
<services>
<service>
<name>Oracle Weblogic AdminServer 1</name>
<state>RUNNING.</state>
</service>
<service>
<name>Oracle WebLogic NodeManager 1</name>
<state>RUNNING.</state>
</service>
<service>
<name>OracleProcessManager_1</name>
<state>RUNNING.</state>
</service>
<service>
<name>OracleProcessManager_2</name>
<state>RUNNING.</state>
</service>
<service>
<name>Oracle WebLogic NodeManager 2</name>
<state>RUNNING.</state>
</service>
<service>
<name>Oracle Weblogic AdminServer 2</name>
<state>RUNNING.</state>
</service>
</services>
</servstate>

我是PowerShell的新手并编写了一个脚本来解析上面的XML作为CSV文件,但我得到了如下结果.

脚本：

$xml = [xml](Get-Content .\monitoring_services.xml)
$xml.servstate.services.service |
    Select-Object @(@{l="name";e={$_.name."#text"}}, @{l="state";e={$_.state."#text"}}) |
    Export-Csv test.csv -NoTypeInformation

结果：

"name","state"
,

,

预期结果：

"name","state"
Oracle Weblogic AdminServer 1,RUNNING.
Oracle WebLogic NodeManager 1,RUNNING.
OracleProcessManager_1,RUNNING.
OracleProcessManager_2,RUNNING.
Oracle WebLogic NodeManager 2,RUNNING.
Oracle Weblogic AdminServer 1,RUNNING.

你能帮忙纠正脚本出了什么问题吗？

$xml.servstate.services.service | Export-Csv test.csv -NoTypeInformation
