## Member Function Documentation

## initialize_context()

void xmlpp::SchemaValidatorBase::initialize_context | ( |  | ) |

overrideprotectedvirtual

Reimplemented from xmlpp::Validator.

Reimplemented in xmlpp::XsdValidator.

## operator bool()

xmlpp::SchemaValidatorBase::operator bool | ( |  | ) | const

explicitoverridepure virtualnoexcept

Test whether a schema has been parsed.

For instance

if (validator)
do_something();

Implements xmlpp::Validator.

Implemented in xmlpp::RelaxNGValidator, and xmlpp::XsdValidator.

## parse_document()

virtual void xmlpp::SchemaValidatorBase::parse_document | ( | const Document * | document | ) |

pure virtual

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

  document | A preparsed document tree, containing the schema definition.

Exceptions

  xmlpp::parse_error |

Implemented in xmlpp::RelaxNGValidator, and xmlpp::XsdValidator.

## parse_file()

void xmlpp::SchemaValidatorBase::parse_file | ( | const std::string & | filename | ) |

overridepure virtual

Parse a schema definition file.

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

Parameters

  filename | The URL of the schema.

Exceptions

  xmlpp::parse_error |

Implements xmlpp::Validator.

Implemented in xmlpp::RelaxNGValidator, and xmlpp::XsdValidator.

## parse_memory()

void xmlpp::SchemaValidatorBase::parse_memory | ( | const ustring & | contents | ) |

overridepure virtual

Parse a schema definition from a string.

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

Parameters

  contents | The schema definition as a string.

Exceptions

  xmlpp::parse_error |

Implements xmlpp::Validator.

Implemented in xmlpp::RelaxNGValidator, and xmlpp::XsdValidator.

## release_underlying()

void xmlpp::SchemaValidatorBase::release_underlying | ( |  | ) |

overrideprotectedvirtual

Reimplemented from xmlpp::Validator.

Reimplemented in xmlpp::XsdValidator.

## validate() [1/2]

void xmlpp::SchemaValidatorBase::validate | ( | const Document * | document | ) |

overridepure virtual

Validate a document, using a previously parsed schema.

Parameters

  document | Pointer to the document.

Exceptions

  xmlpp::internal_error |
  xmlpp::validity_error |

Implements xmlpp::Validator.

Implemented in xmlpp::RelaxNGValidator, and xmlpp::XsdValidator.

## validate() [2/2]

virtual void xmlpp::SchemaValidatorBase::validate | ( | const std::string & | filename | ) |

pure virtual

Validate an XML file, using a previously parsed schema.

Parameters

  filename | The URL of the XML file.

Exceptions
