A Beginner’s Guide to Split Large XML Files in WordPress

XML data is used by most online applications. We can get XML data from various sources, but the data size may be too large. In this article, we will describe how to split large XML files into smaller pieces in WordPress.

Why Splitting Large XML Files in WordPress?

When you are trying to move your blog from WordPress.com to WordPress.org or if you wish to move your content from a self-hosted website to a new server or host you have to export your WordPress content. 

WordPress lets you export your entire website as a single XML file that contains all your posts, pages, images, tag, comments, custom fields, and categories. This is called WXR (WordPress Extended RSS) file.

In some cases, you make find that the file size is larger than the upload limit provided by your WordPress hosting. If in case your file size is large you will not find an error message and you will not be able to import your website content into a new WordPress installation.

Note: The upload limit can vary depending upon the hosting provider.

You can just get in touch with your hosting provider to increase the upload size for a short period of time. But most of the shared hosting providers will not allow it. So in that case you have to split the large XML files into smaller files manually which is a tedious process. 

But there is a better option to do so by installing the WXR File Splitter Tool to reduce your burden.

Reasons to split large XML files in WordPress

There are many reasons why we should split large XML files into smaller parts and then import them into WordPress.

  1. Performance – Loading a file as one chunk does not have any advantage. In fact, it may be slower if the file size is big.
  2. Readability – Reading a large file with more than 5000 lines of code is difficult.
  3. Security – When someone tries to hack your blog, he/she might want to find something interesting inside a single file. So, splitting a file into smaller chunks helps.
