You can open the HTML source code of any Web page in the RubyMine editor.
Note
No matter which programming language was originally used to develop a page (for example, XML or PHP), RubyMine shows the resulting HTML code.
To open the HTML source code of a web page in the editor
Choose File | Open URL.
In the Open URL dialog box that opens, specify the URL address of the desired Web page. Type the URL address manually
or choose a previously specified one from the drop-down list.
