  • Method Details

    • getSource

      public static Source getSource(String baseURI, String relativeURI, SchemaCompiler compiler, NamespaceUri targetNamespaceUri) throws SchemaException
      Resolve and dereference a URI to get a Source object representing a schema document
      Parameters:
      baseURI - the base URI
      relativeURI - the URI to be resolved relative to the base URI
      compiler - the pipeline configuration (which may define a URIResolver to be used)
      targetNamespaceUri - the targetNamespace of the schema document required (this is set to null when doing an include or redefine, because in those cases the targetNamespace cannot be used to locate the schema document)
      Returns:
      the JAXP Source object representing the deferenced URI, or null if no source could be located
      Throws:
      SchemaException - if any errors occur

    • getSources

      public static Source[] getSources(String baseURI, String[] relativeURIs, SchemaCompiler compiler, NamespaceUri targetNamespace) throws SchemaException
      Resolve and dereference a set of URIs to get a set of Source objects representing schema documents
      Parameters:
      baseURI - the base URI
      relativeURIs - the URIs (location hints) to be resolved relative to the base URI
      compiler - the pipeline configuration (which may define a URIResolver to be used)
      targetNamespace - the targetNamespace of the schema document required (this is set to null when doing an include or redefine, because in those cases the targetNamespace cannot be used to locate the schema document)
      Returns:
      the JAXP Source object representing the deferenced URI
      Throws:
      SchemaException - if any errors occur

    • read

      public static SchemaDocument read(Source source, SchemaCompiler compiler, PipelineConfiguration pipe, SchemaElement referrer) throws SchemaException
      Read the Schema from a source XML document and return the Schema document. The schema document is validated against the XML Representation Constraints, but the resulting schema components are not validated against schema component constraints: this must be done by the caller after all schema components are assembled, by calling SchemaCompiler.validate(com.saxonica.ee.schema.sdoc.SchemaDocument)
      Parameters:
      source - the JAXP Source containing the schema document. This may be either a source XSD schema document, or a compiled SCM schema document.
      compiler - used for tracking source documents read, and for error reporting
      pipe - the pipeline configuration
      referrer - if the schema document is referenced from an xs:import, xs:include, or xs:redefined, this parameter identifies that element; otherwise, null.
      Returns:
      the new SchemaDocument created from the source of this SchemaReader. This may be either a source XSD schema document, or a compiled SCM schema document.
      Throws:
      SchemaException - if the schema module can't be read or parsed, or if the schema module is an invalid schema

    • buildSchemaDocument

      public static SchemaDocument buildSchemaDocument(Source source, SchemaCompiler compiler, PipelineConfiguration pipe, SchemaElement referrer) throws SchemaException
      Build the tree representation of a schema document, without doing any processing or XSD-specific validation of the content
      Parameters:
      source - the source of the module
      compiler - the SchemaCompiler (holds configuration information and keeps track of errors)
      pipe - the Pipeline Configuration
      referrer - the xs:import or xs:include element, etc, that requested processing of this module
      Returns:
      the root Document node of the tree containing the schema document
      Throws:
      SchemaException - if XML parsing or tree construction fails

    • setupSourceWithReader

      public static void setupSourceWithReader(Source source, SchemaCompiler compiler, Valve valve, Configuration config, ParseOptions options) throws XPathException
      Throws:
      XPathException
