## Detailed Description

XSD schema validator.

XSD = XML Schema Definition, a.k.a. XML Schema or W3C XML Schema

Since libxml++ 2.38:

## Constructor & Destructor Documentation

xmlpp::XsdValidator::XsdValidator | ( |  | ) |

xmlpp::XsdValidator::XsdValidator | ( | const Glib::ustring & | filename | ) |

explicit

Create a validator and parse a schema definition file.

Parameters

  filename | The URL of the schema.

Exceptions

  xmlpp::parse_error |

xmlpp::XsdValidator::XsdValidator | ( | const Document* | document | ) |

explicit

Create a validator and parse a schema definition document.

Parameters

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

Exceptions

  xmlpp::parse_error |

xmlpp::XsdValidator::XsdValidator | ( | XsdSchema* | schema,
|  | bool | take_ownership
| ) |  |

explicit

Create a validator.

Parameters

  schema | A pointer to the schema to use when validating XML documents.
  take_ownership | If `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.

xmlpp::XsdValidator::~XsdValidator | ( |  | ) |

## Member Function Documentation

XsdSchema* xmlpp::XsdValidator::get_schema | ( |  | ) |

Get the schema.

Returns
  A pointer to the schema, or `nullptr`.

const XsdSchema* xmlpp::XsdValidator::get_schema | ( |  | ) | const

Get the schema.

Returns
  A pointer to the schema, or `nullptr`.

void xmlpp::XsdValidator::initialize_valid | ( |  | ) |

override protected virtual

Reimplemented from xmlpp::SchemaValidatorBase.

virtual xmlpp::XsdValidator::operator BoolExpr | ( |  | ) | const

virtual

Test whether a schema has been parsed.

For instance

if (xsd_validator)
do_something();

Implements xmlpp::SchemaValidatorBase.

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

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 |

Implements xmlpp::SchemaValidatorBase.

virtual void xmlpp::XsdValidator::parse_file | ( | const Glib::ustring & | filename | ) |

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::SchemaValidatorBase.

virtual void xmlpp::XsdValidator::parse_memory | ( | const Glib::ustring & | contents | ) |

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::SchemaValidatorBase.

void xmlpp::XsdValidator::release_underlying | ( |  | ) |

override protected virtual

Reimplemented from xmlpp::SchemaValidatorBase.

void xmlpp::XsdValidator::set_schema | ( | XsdSchema* | 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

  schema | A pointer to the schema to use when validating XML documents.
  take_ownership | If `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.

virtual void xmlpp::XsdValidator::validate | ( | const Document* | document | ) |

virtual

Validate a document, using a previously parsed schema.

Parameters

  document | Pointer to the document.

Exceptions

  xmlpp::internal_error |
  xmlpp::validity_error |

Implements xmlpp::SchemaValidatorBase.

virtual void xmlpp::XsdValidator::validate | ( | const Glib::ustring & | filename | ) |

virtual

Validate an XML file, using a previously parsed schema.

Parameters

  filename | The URL of the XML file.

Exceptions

  xmlpp::internal_error |
  xmlpp::validity_error |

Implements xmlpp::SchemaValidatorBase.
