python - 文档元素 : line 13, 第 2 列之后的垃圾

Question

在解析 xml 文件时，我得到以下回溯

ParseError at /addxml/
junk after document element: line 13, column 2
Request Method: POST
Request URL:    http://localhost:8000/addxml/
Django Version: 1.3.7
Exception Type: ParseError
Exception Value:    
junk after document element: line 13, column 2
Exception Location: /root/Samples/DemoApp/DemoApp/views.py in addxml, line 98
Python Executable:  /usr/bin/python

这是我的代码

if request.POST:
        path = "{0}/app_name/filename.xml".format(settings.PROJECT_ROOT)
        xmlDoc = open(path, 'r')
        xmlDocData = xmlDoc.read()
        xmlDocTree = etree.XML(xmlDocData)

下一行给出了错误

xmlDocTree = etree.XML(xmlDocData)

谢谢

Answer 1

您没有单个根元素。尝试在每个 book 元素上方添加一个父元素。也许书籍？

<books>
  <book> ... </book>
  <book> ... </book>
</books>

如果这没有帮助，请尝试查看第 13 行，如错误消息所建议的那样，第 2 列。

bad_line = xmlDocData.splitlines()[12]
