The abstract markup parser base class.
To implement a parser for your markup format, derive from Glib::Markup::Parser and implement the virtual methods.
You don't have to override all of the virtual methods. If a particular method is not implement the data passed to it will be ignored. Except for the error method, any of these callbacks can throw an error exception; in particular the MarkupError::UNKNOWN_ELEMENT, MarkupError::UNKNOWN_ATTRIBUTE, and MarkupError::INVALID_CONTENT errors are intended to be thrown from these overridden methods. If you throw an error from a method, Glib::Markup::ParseContext::parse() will report that error back to its caller.

Constructs a Parser object.
Note that Markup::Parser is an abstract class which can't be instantiated directly. To implement the parser for your markup format, derive from Markup::Parser and implement the virtual methods.

Called for close tags </foo>
.
This virtual method is invoked when the closing tag of an element is seen.
context | The Markup::ParseContext object the parsed data belongs to. |
element_name | The name of the element. |
Glib::MarkupError | An exception you should throw if something went wrong, for instance if an unknown attribute name was encountered. In particular the MarkupError::UNKNOWN_ELEMENT, MarkupError::UNKNOWN_ATTRIBUTE, and MarkupError::INVALID_CONTENT errors are intended to be thrown from user-implemented methods. |
|
protectedvirtual |
Called on error, including one thrown by an overridden virtual method.
context | The Markup::ParseContext object the parsed data belongs to. |
error | A MarkupError object with detailed information about the error. |
|
protectedvirtual |
Called for strings that should be re-saved verbatim in this same position, but are not otherwise interpretable.
This virtual method is invoked for comments, processing instructions and doctype declarations; if you're re-writing the parsed document, write the passthrough text back out in the same position.
context | The Markup::ParseContext object the parsed data belongs to. |
passthrough_text | The text that should be passed through. |
Glib::MarkupError | An exception you should throw if something went wrong, for instance if an unknown attribute name was encountered. In particular the MarkupError::UNKNOWN_ELEMENT, MarkupError::UNKNOWN_ATTRIBUTE, and MarkupError::INVALID_CONTENT errors are intended to be thrown from user-implemented methods. |
|
protectedvirtual |
Called for open tags <foo bar="baz">
.
This virtual method is invoked when the opening tag of an element is seen.
context | The Markup::ParseContext object the parsed data belongs to. |
element_name | The name of the element. |
attributes | A map of attribute name/value pairs. |
Glib::MarkupError | An exception you should throw if something went wrong, for instance if an unknown attribute name was encountered. In particular the MarkupError::UNKNOWN_ELEMENT, MarkupError::UNKNOWN_ATTRIBUTE, and MarkupError::INVALID_CONTENT errors are intended to be thrown from user-implemented methods. |
|
protectedvirtual |
Called for character data.
This virtual method is invoked when some text is seen (text is always inside an element).
context | The Markup::ParseContext object the parsed data belongs to. |
text | The parsed text in UTF-8 encoding. |
Glib::MarkupError | An exception you should throw if something went wrong, for instance if an unknown attribute name was encountered. In particular the MarkupError::UNKNOWN_ELEMENT, MarkupError::UNKNOWN_ATTRIBUTE, and MarkupError::INVALID_CONTENT errors are intended to be thrown from user-implemented methods. |
