Question

我正在使用Python 101学习并在一个示例中我收到错误并且不知道如何修复它 - 我的代码与书中的100％相同（已经检查过3次）它仍然输出这个错误。这是代码：

from lxml import etree

def parseXML(xmlFile):
    """
    Parse the xml
    """
    with open(xmlFile) as fobj:
        xml = fobj.read()

    root = etree.fromstring(xml)

    for appt in root.getchildren():
        for elem in appt.getchildren():
            if not elem.text:
                text = 'None'
            else:
                text = elem.text
            print(elem.tag + ' => ' + text)

if __name__ == '__main__':
    parseXML('example.xml')

这里是xml文件（它与书中的相同）：

<?xml version="1.0" ?>
<zAppointments reminder-"15">
    <appointment>
        <begin>1181251600</begin>
        <uid>0400000008200E000</uid>
        <alarmTime>1181572063</alarmTime>
        <state></state>
        <location></location>
        <duration>1800</duration>
        <subject>Bring pizza home</subject>
    </appointment>
    <appointment>
        <begin>1234567890</begin>
        <duration>1800</duration>
        <subject>Check MS office webstie for updates</subject>
        <state>dismissed</state>
        <location></location>
        <uid>502fq14-12551ss-255sf2</uid>
     </appointment>
</zAppointments>

编辑：Sry，对我的第一篇文章感到非常兴奋，我实际上忘记了错误代码。

感谢您的帮助!!

Answer 1

可以在此处找到xml中唯一的错误：<zAppointments reminder-"15">，应为：<zAppointments reminder="15">。

将来可以在线找到验证xml的有用工具。例如：https://www.xmlvalidation.com/

Answer 2

错误可能在

中

<zAppointments reminder-"15">

要进行下一次验证，请尝试使用xmllint：

xmllint --valid --noout example.xml

使用lxml模块时出现未知错误 - 解析XML
