The abstract markup parser base class.
<p>
To implement a parser for your markup format, derive from <a class="el" href="classGlib_1_1Markup_1_1Parser.html" title="The abstract markup parser base class.">Glib::Markup::Parser</a> and implement the virtual methods.<p>
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 <a class="el" href="group__Markup.html#g1422c4a583441bbe490b8ed47d7fe1a72a63efd807b6e40451b57e128b34d9f5">MarkupError::UNKNOWN_ELEMENT</a>, <a class="el" href="group__Markup.html#g1422c4a583441bbe490b8ed47d7fe1a7ef0a541fa2885ffc56d0703a55afa735">MarkupError::UNKNOWN_ATTRIBUTE</a>, and <a class="el" href="group__Markup.html#g1422c4a583441bbe490b8ed47d7fe1a74051754fb4e8f11408fe06445e99761e">MarkupError::INVALID_CONTENT</a> errors are intended to be thrown from these overridden methods. If you throw an error from a method, <a class="el" href="classGlib_1_1Markup_1_1ParseContext.html#1158f306b9d7211d97fa02fdfbfddf50" title="Feed some data to the ParseContext.">Glib::Markup::ParseContext::parse()</a> will report that error back to its caller. <hr><h2>Member Typedef Documentation</h2>
