Question

在python中，只需尝试解析XML：

import xml.etree.ElementTree as ET
data = 'info.xml'
tree = ET.fromstring(data)

但得到了错误：

Traceback (most recent call last):
File "C:\mesh\try1.py", line 3, in <module>
tree = ET.fromstring(data)
File "C:\Python27\lib\xml\etree\ElementTree.py", line 1312, in XML
return parser.close()
File "C:\Python27\lib\xml\etree\ElementTree.py", line 1665, in close
self._raiseerror(v)
File "C:\Python27\lib\xml\etree\ElementTree.py", line 1517, in _raiseerror
raise err
xml.etree.ElementTree.ParseError: syntax error: line 1, column 0

那是一些xml，我有：

<?xml version="1.0" encoding="utf-16"?>
<AnalysisData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<BlendOperations OperationNumber="1">

  <Weight>1067.843017578125</Weight>
  <WeightPercent>31.545017776585109</WeightPercent>

为什么会这样？

Answer 1

您尝试解析字符串'info.xml'而不是文件内容。

您可以拨打tree = ET.parse('info.xml')来打开该文件。

或者您可以直接阅读该文件：

ET.fromstring(open('info.xml').read())

尝试使用python解析xml时出错：xml.etree.ElementTree.ParseError：语法错误：第1行，
