## Detailed Description

XML DTD validator.

## Constructor & Destructor Documentation

xmlpp::DtdValidator::DtdValidator | ( |  | ) |

xmlpp::DtdValidator::DtdValidator | ( | const Glib::ustring & | file | ) |
| explicit

Create a validator and parse an external subset (DTD file) immediately.

Parameters

  file | The URL of the DTD.

Exceptions

  xmlpp::parse_error |

xmlpp::DtdValidator::DtdValidator | ( | const Glib::ustring & | external,
|  | const Glib::ustring & | system
| ) |  |
| explicit

Create a validator and parse an external subset (DTD file) immediately.

Parameters

  external | The external ID of the DTD.
  system | The URL of the DTD.

Exceptions

  xmlpp::parse_error |

xmlpp::DtdValidator::~DtdValidator | ( |  | ) |
| override

## Member Function Documentation

Dtd* xmlpp::DtdValidator::get_dtd | ( |  | ) |

Get the parsed DTD.

Returns
  A pointer to the parsed DTD, or `nullptr`.

const Dtd* xmlpp::DtdValidator::get_dtd | ( |  | ) | const

Get the parsed DTD.

Returns
  A pointer to the parsed DTD, or `nullptr`.

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

Test whether a DTD has been parsed.

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

Parse an external subset (DTD file).

If the validator already contains a DTD, that DTD is deleted.

Parameters

  filename | The URL of the DTD.

Exceptions

  xmlpp::parse_error |

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

Parse a DTD from a string.

If the validator already contains a DTD, that DTD is deleted.

Parameters

  contents | The DTD as a string.

Exceptions

  xmlpp::parse_error |

virtual void xmlpp::DtdValidator::parse_stream | ( | std::istream & | in | ) |
| virtual

Parse a DTD from a stream.

If the validator already contains a DTD, that DTD is deleted.

Parameters

  in | The stream.

Exceptions

  xmlpp::parse_error |

virtual void xmlpp::DtdValidator::parse_subset | ( | const Glib::ustring & | external,
|  | const Glib::ustring & | system
| ) |  |
| virtual

Parse an external subset (DTD file).

If the validator already contains a DTD, that DTD is deleted.

Parameters

  external | The external ID of the DTD.
  system | The URL of the DTD.

Exceptions

  xmlpp::parse_error |

void xmlpp::DtdValidator::release_underlying | ( |  | ) |
| override protected virtual

Reimplemented from xmlpp::Validator.

bool xmlpp::DtdValidator::validate | ( | const Document* | doc | ) |

Validate a document, using a previously parsed DTD.

The internal subset (if present) is de-coupled (i.e. not used), which could give problems if ID or IDREF is present.

Parameters

  doc | Pointer to the document.

Returns
  Whether the document is valid.

Exceptions

  xmlpp::internal_error |
  xmlpp::validity_error |
