錯誤試圖使用python解析XML：xml.etree.ElementTree.ParseError：語法錯誤：第1行，

Question

在蟒蛇，只是試圖解析XML：

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

，但得到的錯誤：

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 

這就是一點的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">

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

爲什麼會發生？

Answer 1

您試圖解析字符串'info.xml'而不是文件的內容。您可以撥打tree = ET.parse('info.xml')打開文件。

或者你也可以直接讀取文件：

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