wordpress使用xmlrpc发布文章错误(parse error. not well formed)

一、背景

wordpress带有一个功能，就是使用xmlrpc发布文章。这样子就可以在一些常用的博客客户端中编辑文章，然后提交到wordpress的网站上去。而不需要每次都打开浏览器进行文章编辑。我使用python的是 python的wordpress_xmlrpc模块。但是写好代码运行的时候报错了。

二、错误详情

Traceback (most recent call last):
  File "wordpress.py", line 13, in <module>
    wp = Client('http://ddghgfh.cn/xmlrpc.php', 'sgh4gsd37', 'gsdhgshhb1')

    return u.close()

    raise Fault(**self._stack[0])
xmlrpclib.Fault: <Fault -32700: 'parse error. not well formed'>

三、错误原因

php中缺少相应的xml模块。

四、解决办法

1. 查看php版本

php -v
#输出

2. 搜索模块
