Introduction

The code generator works with:

  • XML Schemas v1.0 & v1.1
  • WSDL v1.1 definitions with SOAP v1.1 bindings
  • DTD external definitions
  • Directly from XML and JSON Documents

The xsdata.codegen.transformer will detect and switch parsers based on the resource extension otherwise it will do some heuristic content searches. Before you start make sure the cli requirements are installed.

$ pip install xsdata[cli]

Command Line Tool

$ xsdata generate --help

Use a directory as source

You can instruct the cli to search all subdirectories recursively with the -r, --recursive flag.

$ xsdata generate project/schemas
$ xsdata generate project/schemas --recursive

Use a filename or URI as source

$ xsdata generate project/schemas/feed.xsd
$ xsdata generate http://www.gstatic.com/localfeed/local_feed.xsd
