解析XML以导出到CSV

以XML格式从IIS配置文件中获取所需数据时出现问题。实际上，我需要在webappname ie（示例/3780）名称中获取一组受限ip地址以及4个数字，然后导出到csv

XML示例

 <location path="Example/3780_Proxy_Test_01418277">
    <system.webServer>
        <security>
            <ipSecurity>
                <add ipAddress="10.10.199.20" allowed="true" />
                <add ipAddress="10.10.81.80" subnetMask="255.255.255.240" allowed="true" />
                <add ipAddress="10.10.199.16" subnetMask="255.255.255.240" allowed="true" />
                <add ipAddress="10.10.163.150" allowed="true" />
                <add ipAddress="10.10.163.151" allowed="true" />
            </ipSecurity>
        </security>
    </system.webServer>
</location>
<location path="Example/3200_Proxy">
    <system.webServer>
        <security>
            <ipSecurity>
            </ipSecurity>
        </security>
    </system.webServer>
</location>

xPath区分大小写

select xml-path$path-xpath'//ipsecurity'

不返回任何内容，但

select xml-path$path-xpath'//ipsecurity'

返回预期的5个节点。xpath区分大小写

select xml-path$path-xpath'//ipsecurity'

不返回任何内容，但

select xml-path$path-xpath'//ipsecurity'

返回预期的5个节点。

$path = "\path\to\whatever.xml"
$xpath = "/configuration/location/system.webserver/security/ipsecurity"
select-xml -path $path -xpath $xpath |select-object ipaddress
