用WLW发布WordPress乱码解决方案(转自新克蘭德)

Posted on 2009年06月1日 by 老豆豉

换空间之后，用WLW远程发布日志时，出现问题：html标签处理不当(<>&等三个符号显示不出来)，Google了一下原因，才知道是一个处理XML的函式库libxml2出了问题。新克蘭德已经给出了解决办法，按照此办法修改相关页面后，问题解决。把办法转在这里，以后升级WP时备查。

方法简述：

修改下述三个php文件里面的一个function (注意各人文件内容不尽相同)

  • /wp-admin/import/blogger.php — function parse($xml)
  • /wp-includes/rss.php — function MagpieRSS ($source)
  • /wp-includes/class-IXR.php — function parse()

依照下面的方式修改：
