Question

您好我在解析以下xml文件时遇到以下错误，（无法找到xml文件的任何问题）。我希望这个xml在没有失败的情况下传递解析。我使用xml.etree进行解析，我在etree中使用formtring方法。我正在使用：

import xml.etree.ElementTree as ET
root_payload = ET.fromstring(xml_file)

请帮助。

您的xml未关闭。添加xml的这一行

</adtn-subs-trace:traces>

为xml添加名称空间。并将xmlms更改为xmlns。在您的名称空间中（xmlns = XML名称空间）。

<?xml version="1.0"?>
<adtn-subs-trace:traces xmlns:adtn-subs-trace="http://www.adtran.com/ns/yang/adtran-subsystem-traces">

python XML解析错误：＆＃39; ParseError：未绑定的前缀：＆＃39; （无法找到xml文件的任何问题）
