WordPress currently supports importing data in the form of posts (articles) and most of the details or features supported by the content publishing platform.
Many of the following Content Import scripts can be found under Tools → Import menu of your WordPress administration interface.
If you run into specific problems, a search on the WordPress Support Forum will likely lead to a solution, or try the Codex FAQ. Users of a blogging system not listed here who wish to switch to WordPress are invited to ask for help in the WordPress Support Forum as well.
If your exported file is very large, the import script may run into your host's configured memory limit for PHP.
A message like "Fatal error: Allowed memory size of 8388608 bytes exhausted" indicates that the script can't successfully import your XML file under the current PHP memory limit. If you have access to the php.ini file, you can manually increase the limit; if you do not (your WordPress installation is hosted on a shared server, for instance), you will have to break your exported XML file into several smaller pieces and run the import script one at a time.
If the import process is run again with the same data file after stopping midway through, it could result in duplicate data, missing data or other errors in the destination database.
For those with shared hosting, the best alternative may be to consult hosting support to determine the safest approach for running the import. A host may be willing to temporarily lift the memory limit and/or run the process directly from their end.

First, save the RSS feed you wish to import someplace on your local machine. This would be the source and would come from the site that has the content you wish to import into your WP blog. A simple way to get the feed into a text file is to find the RSS link for that site, click it and view it in your browser, then copy/paste that to a text file. Or, of course, use your preferred tools.
Click the "Browse" button and navigate to the file containing the feed you wish to import and click "Import" to let it run.
Note: Depending on the feed and format, you may not get the entire thing loaded on the first attempt. One option is to determine how much got imported (Manage -> Posts) and remove those sections from your saved RSS file and then re-import. Lather, rinse, repeat as necessary.
Note that newlines will be converted to <br />. Therefore be sure there is no newlines between any <p>..</p>s.
WordPress also has a generic RSS importer, which you can find in your WordPress source at wp-admin/import-rss.php. If your current blogging system can export in a valid RSS format, you can import that into WordPress.
Importing the RSS data is done by running the import-rss.php script from the server. For security reasons you have to edit the script to point to the file where the RSS data is stored.
If you have your blog at http://example.com, you can place your file, for example oldblog.xml, in the wp-admin directory on your site.
Edit import-rss.php by changing the value of RSSFILE in the beginning of the script. After you have changed this, run the script by accessing the script with your browser, in this case you’ll go to http://example.com/wp-admin/import-rss.php.
If the script finds your file, a link marked Begin RSS Import occur, and by pressing this link the import will start.
The RSS data are now imported, and you can remove the RSS file and restore the script.
Using trial and error one can make an e.g., perl script to concatenate [X]HTML files as RSS <item>s, saving into a single file.xml, then import that as RSS. Note however to first remove any newlines between <p>..</p>s, as mentioned above.
The format allowed is quite simple in fact. Just make each HTML file into an <item> as below and concatenate them together:
<item> <pubDate>Wed, 30 Jan 2009 12:00:00 +0000</pubDate> <category>Kites</category> <category>Taiwan</category> <title>Fun times</title> <content:encoded><p>What great times we had...</p><p>And then Bob...</p></content:encoded> </item> <item>...
Just be sure the <content:encoded> line is a single long line with no newlines embedded.
If your HTML is well-formed, you can try using the Import HTML plugin.
