解析XML以导出为CSV

Question

从XML格式的IIS配置文件中获取我想要的数据时遇到问题。基本上，我需要获取一堆受限的IP地址以及webappname中的4个数字，即（Example / 3780）名称，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>

现在，我只停留在基础知识上，只是想让所有东西匹配

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