使用lxml模块解析XML时出现未知错误
使用lxml模块解析XML时出现未知错误
提问于 2016-11-29 20:19:33
我现在正在使用Python 101进行学习，在其中一个例子中，我得到了一个错误，并且不知道如何修复它--我的代码与书中的100%相同(已经检查了3次)，它仍然输出这个错误。以下是代码：
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')下面是xml文件(与书中的相同)：
<?xml version="1.0" ?>

</zAppointments>编辑: Sry，对我的第一篇文章非常兴奋，以至于我实际上忘了输入错误代码。

xml中唯一的错误可以在这里找到：<zAppointments reminder-"15">，应该是：<zAppointments reminder="15">。
将来，可以在网上找到验证xml的有用工具。例如：https://www.xmlvalidation.com/
