## Constructor & Destructor Documentation

xmlpp::TextReader::TextReader | ( | struct _xmlTextReader * | cobj ) |

Wraps a TextReader object from an underlying libxml object.

The TextReader takes ownership of cobj.

Parameters:

  cobj | The underlying libxml xmlTextReader object.

xmlpp::TextReader::TextReader | ( | const Glib::ustring & | URI ) |

Creates a new TextReader object to parse a file or URI.

Parameters:

  URI | The URI to read.

xmlpp::TextReader::TextReader | ( | const unsigned char * | data,
|  | size_type | size,
|  | const Glib::ustring & | uri = `Glib::ustring()`
| ) |  |

Creates a new TextReader object which parses in memory data.

Parameters:

  data | The data to parse.
  size | The number of bytes in data.
  uri | The base URI of the file.
