在Robot Framework中运行Netconf未返回正确的输出

Question

当我试图在Robot Framework中执行netconf命令时，出现以下错误。如果我错过了什么/做错了什么，请告诉我。谢谢

Testcase - Netconf Operation Command in Junos Router

    # Manually turn on netconf in Juniper Networks router
    # command = set system services netconf ssh, commit

    # Juniper Network Router's IP Address
    ${dev_ip} =      Set Variable    192.168.0.1

    ${netconf_cmd}=    catenate     SEPARATOR=
    ...    echo '\\<rpc\\>\\n
    ...        \\<get-interface-information/\\>\\n
    ...    \\</rpc\\>\\n
    ...    ' | sshpass -p a_password ssh admin@${dev_ip} netconf

    ${result} =    Run Process    ${netconf_cmd}    shell=True

    Log To Console    ${\n}Netconf command output: $${result.stdout}${\n}

输出不正确，它只是存储netconf的初始问候消息，而不是数据请求的输出。

输出：

Netconf command output: $<!-- No zombies were killed during the creation of this user interface -->
<!-- user regress, class j-superuser -->

从输出消息中，我怀疑xml输入有问题。请验证已发送的rpc消息。响应显示为netconf错误。

Netconf会话与hello交换已完成。发送rpc失败
