Xml 编辑配置的值Powershell

我熟悉powershell中的引用节点，但不完全确定如何编辑以下节点，因为每个值都没有唯一的标识符。我可以根据路径编辑这些值吗？每个路径引用一个SSIS变量。我只需要编辑configuredValue，但这是跨15个节点的。以下是这些节点的两个示例：

<Configuration ConfiguredType="Property" Path="\Package.Variables[User::var1].Properties[Value]" 
    ValueType="String">
        <ConfiguredValue>SomeValue</ConfiguredValue>
 </Configuration>
 <Configuration ConfiguredType="Property" Path="\Package.Variables[User::var2].Properties[Value]" 
    ValueType="String">
        <ConfiguredValue>AnotherValue</ConfiguredValue>
</Configuration>

有可能：

# xml object to use in example
[xml]$xml = @"
<root>
    <Configuration ConfiguredType="Property" Path="\Package.Variables[User::var1].Properties[Value]" 
        ValueType="String">
            <ConfiguredValue>SomeValue</ConfiguredValue>
     </Configuration>
     <Configuration ConfiguredType="Property" Path="\Package.Variables[User::var2].Properties[Value]" 
        ValueType="String">
            <ConfiguredValue>AnotherValue</ConfiguredValue>
    </Configuration>
</root>
"@

这太有用了！感谢您的快速回复+1.

            <ConfiguredValue>SomeValue</ConfiguredValue>
     </Configuration>
     <Configuration ConfiguredType="Property" Path="\Package.Variables[User::var2].Properties[Value]" 
        ValueType="String">
