python - wordpress导出的xml转成.md文件

最近在搭建一个jekyll到Github上，考虑到以前的wordpress站很多文章都是有用的，于是找了很多方法来迁移wordpress上面的文章；
网上找了各种办法，适合windows而且更多人选择的就是exitwp了，但是在使用过程中出现了这个问题：

python exitwp.py

reading: wordpress-xml\wordpress.xml
Traceback (most recent call last):
  File "exitwp.py", line 373, in 
    data = parse_wp_xml(wpe)
  File "exitwp.py", line 85, in parse_wp_xml
    root = tree.parse(file, parser)
  File "C:\Python27\lib\xml\etree\ElementTree.py", line 656, in parse
    parser.feed(data)
  File "C:\Python27\lib\xml\etree\ElementTree.py", line 1653, in feed
    self._raiseerror(v)
  File "C:\Python27\lib\xml\etree\ElementTree.py", line 1517, in _raiseerror
    raise err
xml.etree.ElementTree.ParseError: not well-formed (invalid token): line 13516, column 6

网上找到类似修改exitwp.py的输出格式为utf-8的，尝试无果，求大神指点~
