Generating DTD

A Data Type Definition (DTD) is required for running structure validation checks on a web content file. PhpStorm can scan any XML file for the existing elements and attributes and generate a DTD for it.

Generate a DTD for an XML file

Open the file in the editor.
In the main menu, go to Tools | XML Actions | Generate DTD From XML File. PhpStorm inserts the resulting DTD as a section above the first line of the file.

Open the .dtd file in the editor and select Tools | XML Actions | Convert Schema from the main menu. The Convert Schema File dialog opens.
In the Output type area, specify the format for the generated schema. The available options are:
Specify the encoding, indentation, and maximum line length.
In the Output Destination field, specify where you want the generated schema file to be stored.
Optionally:
Click Advanced and specify additional options in the Advanced Conversion Options dialog that opens. For more information, refer to the RELAX NG official website.
