Generating XML schemas from instance documents
An XSD (XML Schema Definition) is required for running structure validation checks on a Web content file. WebStorm can scan any XML file for the existing elements and attributes and generate a Schema for it.

and select the desired file in the dialog that opens.In the Result Schema File Name text box, specify the name of the output file to place the generated Schema in.
Specify the location of the generated Schema. By default, the generated Schema file will be placed in the same directory as the source XML instance document. To specify another location, click Browse
and select the desired path in the dialog that opens.From the Design Type list, select the way to declare elements and complex types.
From the Detect Simple Content Type list, select the type to use for leaf text.
