python读取xml文件并转换为csv文件

我正在尝试将xml文件转换为csv文件。如何读取和解析xml文件并转换为csv？是否有将xml转换为csv的包

<services>
    <service>
        <ServiceID>1</ServiceID>
        <ServiceName>eVoting Booth</ServiceName>
    </service>
    <service>
        <ServiceID>2</ServiceID>
        <ServiceName>Justice of the Peace</ServiceName>
    </service>
    <service>
        <ServiceID>3</ServiceID>
        <ServiceName>Library</ServiceName>
    </service>
        <service>
        <ServiceID>4</ServiceID>
        <ServiceName>Customer Service</ServiceName>
    </service>
    <service>
        <ServiceID>5</ServiceID>
        <ServiceName>Migrant Service</ServiceName>
    </service>
</services>

类似这样的方法可能会奏效：

从lxml导入etree
作为pd进口熊猫
tree=etree.parse（“input.xml”）
df=pd.DataFrame({
“ServiceID”：tree.xpath（'/services/service/ServiceID/text（）'），
“ServiceName”：tree.xpath（“/services/service/ServiceName/text（）”）
})
df.to_csv（“output.csv”，sep=“|”，index=None）

这就产生了

ServiceID|ServiceName
1|eVoting Booth
2|Justice of the Peace
3|Library
4|Customer Service
5|Migrant Service

你试过什么？看见

ServiceID|ServiceName
1|eVoting Booth
2|Justice of the Peace
3|Library
4|Customer Service
5|Migrant Service
