ikiwiki/doc/tips/Importing_posts_from_Wordpress.mdwn

Use case: You want to move away from Wordpress to Ikiwiki as your blogging/website platform, but you want to retain your old posts.

[This](http://git.chris-lamb.co.uk/?p=ikiwiki-wordpress-import.git) is a simple tool that generates [git-fast-import](http://www.kernel.org/pub/software/scm/git/docs/git-fast-import.html)-compatible data from a WordPress export XML file.

WordPress categories are mapped onto Ikiwiki tags. The ability to import comments is planned.

The script uses the [BeautifulSoup][] module.

I include a modified version of this script. This version includes the ability to write \[[!tag foo]] directives, which the original intended, but didn't actually do.

Perhaps slightly insane, but here's an XSLT style sheet that handles my pages.  It's basic, but sufficient to get started.
Note that I had to break up the ikiwiki meta strings to post this.
