When you export all your post data from BlogEngine and try to import the data file into WordPress using Aaron Lerch’s BlogML import class, I found that it does not include any of the commentators URL’s, which means all those comments that my readers left would no longer be a link. I find that very unacceptable.
The BlogML import class also left out all tags on my 350 posts. I don’t want to go back through all those posts creating new tags for them after I perform the transition, so I decided that I would spend some time modifying the BlogML class so that these two issues would be resolved.
After some testing and tweaking, I was able to accommodate both of my requirements and make the transition from BlogEngine to WordPress a little more nice.
This version does everything that Aaron’s BlogML class does, with my two additions included.
Installation Instructions
Simply copy to BlogML.php file into your /wp-admin/import/ folder. Once you do, you will see the BlogML import format as a selection on the Tools – Import screen.
Install the Php.XPath class into the same folder as the BlogML class.
Download
You can download the updated class from one of my other sites until I have a chance to make the migration and place the file into a directory on my new host.

You will also need
Php.XPath library available from SourceForge (Get version 3.5)
Support
I’ve tried my best to ensure that everything happens smoothly with the import, however if you have any issues, please feel free to leave a comment here or contact me.

Do you have an updated script for wordpress 2.9

awsome man,thanks a lot
Jeff´s last blog ..Hello world！
I am planning to migrate on WordPress too. Unfortunately link on your updated class is broken. Can you fix it, please?
says:
Fixed! Thanks for alerting me to that.

You can get all the 301 redir info you need from the import log that is created. I used Excel to put the lines altogether properly, and copied to the .htaccess file, done. Each import will wipe any prior logs, so grab the log data after each import.
Right on, just got your email too… thanks for being so responsive – I like that.
I got it to work on my local server on my laptop… the categories were the long ID’s that blogml used, but i just looked at the CDATA that was in the xml associated with the ID’s and manually edited those in the DB. I had to get rid of the tags he used on the blog… TONS of tags… and obviously BlogML doesn’t do proper taxonomy because a lot of the tag slugs were the same as what the category slugs were. He was doing tags all wrong so I wiped them and did the tags properly, but would be something to look at for anybody else in the future.
I don’t think it’ll ever be seamless but getting that initial start, importing the 600+ posts was the biggest thing….
Now I just need to do the 301 redirects… sigh…
Take it easy man! and thanks again!

I know what you’re going though. What I had to do was split the export into several export files, 1, 2 and 3 in my case. By splitting the file up into smaller ones, you can import each one, one after the other.
The xml file has nodes in the beginning and ending part of the big file that you’ll want to have in each of the files you create. Like the category info and what-not. The importer needs that info to be there to work as it will look for it during the import process.
As for the categories, I ignored them in my particular case as I decided to redefine my cats, which subsequently also forced me to give each post a new category once the import was complete for each file.
You might try, and I didn’t test this, but I believe you might be able to edit the exported file and modify the guid’s into category names. You might have to do a find-replace operation on the whole file as I cannot remember if the post items referenced the guid or name of the category. If they reference the guid, then once you change the category definition, you will most likely have to change the posts category guid as well to match whatever text you give them.
I hope that helps. I’m pretty distracted right now as I write this, but I think you might understand all this. If not, feel free to hit me up with any more questions you might have.
I originally found Aaron’s but was having some weird issues with step1 after import of the xml file… Found your post and was hopeful since it was over a year newer… but I’m still having issues using the importer.
Fatal error: Out of memory (allocated 41943040) (tried to allocate 262144 bytes) in /home/username/public_html/wp-admin/import/XPath.class.php on line 2163
Installed a local copy of WP and increased the php memory
ini_set(‘memory_limit’,’128M’);
… that allowed the import to run but only on my local copy, won’t work for the site online. So I have the posts, users, and the categories… well – about the categories…
The categories imported the name and the slug as the ID from blogML… can’t edit them because for some reason the slug already exists? IDK but I’m going through it now to figure out that portion of it…
Wondering if you experienced that at all?

Hi,
Great tool.
I seem to gave a small problem with my BlogML file exported from blogengine.
when I import it to WordPress, It works fine, but most of post are posted without content, while the content is there in BlogML.xml
any solution?
says:
Check to make sure that you’re not running into a character encoding issue. If you’re going from Windows to a Linux system, that might be the cause. I’ve hit that a few times, but that is the only thing I can think of that might cause that issue. Unless there is something about the way the export formatted the file, or something in your content…
says:
You might want to make sure that you didn’t change the character encoding of the file, or *gulp* if I have a different encoding in the file.
I believe that will be the problem now that I’ve had a chance to consider the issue a bit.
Ok, just to double check.. are you using v2.8 of WordPress? If I remove the blogml.php file from the imports dir then all the importers are visible again, weird.
It might just be best to reinstall WordPress and try again.
Thanks!
I’m trying to import my BlogML exported file (from BlogEngine.Net) but when I use your’s/Aaron’s BlogML import class my Tools->Import page is blank.
You wouldn’t happen to have any ideas on how to remedy this?
says:
If you don’t see the list of importers under the Tools – Import page, then I would suspect a bad install of WordPress. I went through several iterations without an issue like you describe, so I’m not sure what might be causing it.
I think the user was talking about to the blank page shown once pressed onto import. That’s what I got. Any idea? BlogML file is in UTF8 as suggested somewhere.
says:
But did the import work? I don’t recall anything of my own effort since it was many months ago…but I might imagine blank page appearing due to the size (timeout?) of the import. I had to break my import into 3 chunks, and import each one to do my entire set of posts.
Perhaps that’s what we’re talking about?
I get the same issue. Blank page after you choose what platform you’re importing from. Before you start the import. I have been trying for weeks to figure it out…
I found the answer. Turn off all of your plugins and then try the import. it worked for me..
says:
Excellent information. Always good to see people share their real experience from transitions like this.
Getting closer….
