如何使用python将xml属性解析到表中？

Question

你好，我正在尝试将一些xml数据解析到一个表中。我可以使用dom解析器轻松地获取xml元素，但我想知道访问属性然后将它们放入表之类的数据结构的最佳方法。你知道吗

<Module name="Filter_Module1">
    <register name="Control/Status_reg" offset="64">
        <field name="" offset="63" power_upval="0" access="R" isreset="cleared to 0">
            <description> Error:Received two Footer Packets with no corresponding Header or Data Packets.</description> 
        <field>

        <field name="" offset="62" power_upval="0" access="R" isreset="cleared to 0">
            <description> Received no footer packet after a data packet.  Can only be cleared by a reset</description> 
        <field>

        <field name="" offset="61" power_upval="0" access="R" isreset="cleared to 0">
            <description> Received no data packets between a header and a footer packet.  Can only be cleared by a reset.</description> 
        <field>

        <field name="" offset="60" power_upval="0" access="R" isreset="cleared to 0">
            <description> Error:Received two Footer Packets with no corresponding Header or Data Packets.</description> 
        <field>

    </register>
</Module>

<Module name="SRAM"></Module>

使用XPATH。lxml库提供对解析xml和执行XPATH查询的支持
