Detailed Description

RelaxNG schema validator.

RelaxNG = REgular LAnguage for XML Next Generation

Since libxml++ 2.38:

Constructor & Destructor Documentation

xmlpp::RelaxNGValidator::RelaxNGValidator ( )
xmlpp::RelaxNGValidator::RelaxNGValidator ( const std::string filename)
explicit

Create a validator and parse a schema definition file.

The schema must be defined with XML syntax (.rng file). The compact syntax (.rnc file) is not supported.

Parameters
filenameThe URL of the schema.
Exceptions
xmlpp::parse_error
xmlpp::RelaxNGValidator::RelaxNGValidator ( const Document document)
explicit

Create a validator and parse a schema definition document.

Parameters
documentA preparsed document tree, containing the schema definition.
Exceptions
xmlpp::parse_error
xmlpp::RelaxNGValidator::RelaxNGValidator ( RelaxNGSchema schema,
bool  take_ownership 
)
explicit

Create a validator.

Parameters
schemaA pointer to the schema to use when validating XML documents.
take_ownershipIf true, the validator takes ownership of the schema. The caller must not delete it.

If false, the validator does not take ownership of the schema. The caller must guarantee that the schema exists as long as the validator keeps a pointer to it. The caller is responsible for deleting the schema when it's no longer needed.

Member Function Documentation

RelaxNGSchema* xmlpp::RelaxNGValidator::get_schema ( )
noexcept

Get the schema.

Returns
A pointer to the schema, or nullptr.
const RelaxNGSchema* xmlpp::RelaxNGValidator::get_schema ( ) const
noexcept

Get the schema.

Returns
A pointer to the schema, or nullptr.
void xmlpp::RelaxNGValidator::initialize_context ( )
overrideprotectedvirtual

Reimplemented from xmlpp::Validator.

xmlpp::RelaxNGValidator::operator bool ( ) const
explicitoverridevirtualnoexcept

Test whether a schema has been parsed.

For instance

if (relaxng_validator)
do_something();

Implements xmlpp::SchemaValidatorBase.

void xmlpp::RelaxNGValidator::parse_document ( const Document document)
overridevirtual

Parse a schema definition from a document.

If the validator already contains a schema, that schema is released (deleted if the validator owns the schema).

Parameters
documentA preparsed document tree, containing the schema definition.
Exceptions
xmlpp::parse_error

Implements xmlpp::SchemaValidatorBase.

void xmlpp::RelaxNGValidator::parse_file ( const std::string filename)
overridevirtual

Parse a schema definition file.

The schema must be defined with XML syntax (.rng file). The compact syntax (.rnc file) is not supported.

If the validator already contains a schema, that schema is released (deleted if the validator owns the schema).

Parameters
filenameThe URL of the schema.
Exceptions
xmlpp::parse_error

Implements xmlpp::SchemaValidatorBase.

void xmlpp::RelaxNGValidator::parse_memory ( const ustring contents)
overridevirtual

Parse a schema definition from a string.

The schema must be defined with XML syntax. The compact syntax is not supported.

If the validator already contains a schema, that schema is released (deleted if the validator owns the schema).

Parameters
contentsThe schema definition as a string.
Exceptions
xmlpp::parse_error

Implements xmlpp::SchemaValidatorBase.

void xmlpp::RelaxNGValidator::release_underlying ( )
overrideprotectedvirtual

Reimplemented from xmlpp::Validator.

void xmlpp::RelaxNGValidator::set_schema ( RelaxNGSchema schema,
bool  take_ownership 
)

Set a schema.

If the validator already contains a schema, that schema is released (deleted if the validator owns the schema).

Parameters
schemaA pointer to the schema to use when validating XML documents.
take_ownershipIf true, the validator takes ownership of the schema. The caller must not delete it.

If false, the validator does not take ownership of the schema. The caller must guarantee that the schema exists as long as the validator keeps a pointer to it. The caller is responsible for deleting the schema when it's no longer needed.
void xmlpp::RelaxNGValidator::validate ( const Document document)
overridevirtual

Validate a document, using a previously parsed schema.

Parameters
documentPointer to the document.
Exceptions
xmlpp::internal_error
xmlpp::validity_error

Implements xmlpp::SchemaValidatorBase.

void xmlpp::RelaxNGValidator::validate ( const std::string filename)
overridevirtual

Validate an XML file, using a previously parsed schema.

Parameters
filenameThe URL of the XML file.
Exceptions
xmlpp::internal_error
xmlpp::parse_error
xmlpp::validity_error

Implements xmlpp::SchemaValidatorBase.
