Generating XML schemas from instance documents

Last modified: 17 March 2022

tip

To suppress Schema enumeration, specify 0.

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

Generate a Schema based on an XML document

  1. With the desired XML document opened in the active editor tab, choose Tools | XML Actions | Generate XSD Schema from XML File on the main menu. The Generate Schema From Instance Document dialog box opens.

  2. In the Instance Document Path text box, specify the location of the file to be used as the basis for Schema generation. By default, the field shows the full path to the current file. Accept this suggestion or click Browse the Browse button and select the desired file in the dialog that opens.

  3. In the Result Schema File Name text box, specify the name of the output file to place the generated Schema in.

    warning

    AppCode suggests the name of the source XML document with the .xsd extension. If you type another name, make sure the extension is correct.

  4. 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 the Browse button and select the desired path in the dialog that opens.

  5. From the Design Type drop-down list, select the way to declare elements and complex types.

  6. From the Detect Simple Content Type drop-down list, select the type to use for leaf text.

  7. In the Detect Enumerations Limit text box, type the number of occurrences to cause appearance of the Schema enumeration.
