Sharepoint - Importing WordPress to SharePoint

I know this is old, but I was also frustrated, that nobody had done this before. I decided to write my migration script in powershell. If you ever need something like this again, give it a try: http://memyselfandbenchase.blogspot.de/2015/07/migrate-your-wordpress-blog-to.html

Hope it helps someone else.

Here is the script. Sorry that it is so long.

#requires -version 3  
 <#  
 .SYNOPSIS  
  This script migrates a wordpress blog to a sharepoint blog.  
 .DESCRIPTION  
  This script migrates a wordpress blog to a sharepoint blog.  
  It is based on the xml export from wordpress. It then parses all the  
  posts, comments and categories. It changes all of the links and  
  uploads the files/images in the posts to the sharepoint library.  
  In order for this to work, the wordpress blog is expected to still be  
  reachable through the links in the export. The user names are preserved  
  as long as the users are also available in sharepoint. Otherwise, the  
  Post/comment is carried out as another defined user.  
 .PARAMETER   
  none  
 .INPUTS  
  none  
 .OUTPUTS  
  Saves uploads from wordpress in .\uploads
