relaxng.compile-schema

function

Library: RELAX NG (OMRELAXNG)
Import : omrelaxng.xmd

Returns: compiled RELAX NG schema

Declaration

export relaxng-schema-type function
   compile-schema value string source schema-input

Purpose

Use compile-schema to compile a RELAX NG schema specified in XML format, so that you may validate XML input against it. Compiling the schema also serves to validate the schema itself.

If the schema is invalid and cannot be compiled, compile-schema throws the compile-error exception.

Example

In this example we compile the schema "my-schema" and validate XML input against it, reporting any errors along the way:

  import "omrelaxng.xmd" prefixed by relaxng.
  
  process
     local relaxng.relaxng-schema-type example-schema
  
     set example-schema to relaxng.compile-schema file "example-schema.rng"
  
     do xml-parse scan file "example-input.xml"
        do markup-parse relaxng.validated #content against example-schema
           output "%c"
        done
     done
  
  element #implied
     output "%c"
