Obsidian Regex Mark is a plugin for Obsidian that allows you to add custom CSS classes to text based on regular expressions.

Add a regular expression and a CSS class to the plugin settings. The plugin will then add the CSS class to any text that matches the regular expression.

And data-contents will be added to the span tag

The following regular expression will add the CSS class comment to any text that matches the regular expression.

regex: //.*$
class: comment

And the following text

This is a normal line of text. //This is a comment.

will be converted to

<p>This is a normal line of text. <span class="comment" data-contents="//This is a comment">//This is a comment.</span></p>

You can then use the CSS class to style the text in your CSS snippet or any other usages.
