简单的xml文件解析都报错~

文件名sample1.xml在c盘根目录
内容：
<?xml version=”1.0″ encoding=”utf-8″?>
<catalog>
  <maxid>4</maxid>
  <item id=”1″>
  <caption>Python</caption>
  <item id=”4″>
  <caption>ceshi</caption>
  </item>
  </item>
  <item id=”2″>
  <caption>Zope</caption>
  </item>
</catalog>

python代码如下：
from xml.dom import minidom 

xmldoc=minidom.parseString('c:\sample1.xml')
print xml.doc
print xmldoc.toxml()

报错如下：
Traceback (most recent call last):
  File "C:\Users\Administrator\Desktop\2011-10-26\3.py", line 3, in <module>
  xmldoc=minidom.parseString(r'c:\sample1.xml')
  File "C:\Python26\Lib\site-packages\_xmlplus\dom\minidom.py", line 1925, in parseString
  return expatbuilder.parseString(string)
  File "C:\Python26\Lib\site-packages\_xmlplus\dom\expatbuilder.py", line 942, in parseString
  return builder.parseString(string)
  File "C:\Python26\Lib\site-packages\_xmlplus\dom\expatbuilder.py", line 223, in parseString
  parser.Parse(string, True)
ExpatError: not well-formed (invalid token): line 1, column 2

到底什么意思？怎么第一步都走不通。。。
高人指点啊

Python code

from xml.dom import minidom  

xmldoc=minidom.parse('c:\sample1.xml')
print xmldoc.toxml()

你的代码我复制进去直接报错啊。。哥哥

你的xml文件有问题,造成无法解析!!

修改一下.

XML code

<catalog>
  <maxid>4</maxid>
  <item id=”1″>
      <caption>Python</caption>
  <item id=”4″>
      <caption>ceshi</caption>
  </item>                            !!!!!!!!
  </item>
  <item id=”2″>
      <caption>Zope</caption>
  </item>
</catalog>
