This is a small, efficient, easy-to-useparser. It should not be used if you expect to interoperate with other applications generating full-scale XML. However, it's very useful forapplication data files, config files, etc. where you know yourapplication will be the only one writing the file. Full-scale XMLparsers should be able to parse the subset used by GMarkup, so you caneasily migrate to full-scale XML at a later time if the need arises.</p><p>GMarkup is not guaranteed to signal an error on all invalid XML; theparser may accept documents that an XML parser would not. However, XML documents which are not well-formed<sup>[<a name="wellformed" href="#ftn.wellformed" class="footnote">5</a>]</sup> are not considered valid GMarkup documents. </p><p>Simplifications to XML include:</p><div class="itemizedlist"><ul type="disc"><li><p>Only UTF-8 encoding is allowed.</p></li><li><p>No user-defined entities.</p></li><li><p>Processing instructions, comments and the doctype declaration are "passed through" but are not interpreted in any way.</p></li><li><p>No DTD or validation.</p></li></ul></div><p></p><p>The markup format does support:</p><div class="itemizedlist"><ul type="disc"><li><p>Elements</p></li><li><p>Attributes</p></li><li><p>5 standard entities: <code class="literal">&amp; &lt; &gt; &quot; &apos;</code></p></li><li><p>Character references</p></li><li><p>Sections marked as CDATA</p></li></ul></div><p></p></div><div class="refsect1" lang="en"><a name="id3164723"></a><h2>Details</h2><div class="refsect2" lang="en"><a name="id3164734"></a><h3><a name="GMarkupError"></a>enum GMarkupError</h3><a class="indexterm" name="id3164747"></a><pre class="programlisting">typedef enum{ G_MARKUP_ERROR_BAD_UTF8, G_MARKUP_ERROR_EMPTY, G_MARKUP_ERROR_PARSE, /* The following are primarily intended for specific GMarkupParser * implementations to set. */ G_MARKUP_ERROR_UNKNOWN_ELEMENT, G_MARKUP_ERROR_UNKNOWN_ATTRIBUTE, G_MARKUP_ERROR_INVALID_CONTENT, G_MARKUP_ERROR_MISSING_ATTRIBUTE} GMarkupError;</pre><p>Error codes returned by markup parsing.</p><div class="variablelist"><table border="0"><col align="left" valign="top"><tbody><tr><td><p><span class="term"><a name="G-MARKUP-ERROR-BAD-UTF8:CAPS"></a><code class="literal">G_MARKUP_ERROR_BAD_UTF8</code></span></p></td><td>text being parsed was not valid UTF-8</td></tr><tr><td><p><span class="term"><a name="G-MARKUP-ERROR-EMPTY:CAPS"></a><code class="literal">G_MARKUP_ERROR_EMPTY</code></span></p></td><td>document contained nothing, or only whitespace</td></tr><tr><td><p><span class="term"><a name="G-MARKUP-ERROR-PARSE:CAPS"></a><code class="literal">G_MARKUP_ERROR_PARSE</code></span></p></td><td>document was ill-formed</td></tr><tr><td><p><span class="term"><a name="G-MARKUP-ERROR-UNKNOWN-ELEMENT:CAPS"></a><code class="literal">G_MARKUP_ERROR_UNKNOWN_ELEMENT</code></span></p></td><td>error should be set by <a class="link" href="glib-Simple-XML-Subset-Parser.html#GMarkupParser"><span class="type">GMarkupParser</span></a> functions; element wasn't known</td></tr><tr><td><p><span class="term"><a name="G-MARKUP-ERROR-UNKNOWN-ATTRIBUTE:CAPS"></a><code class="literal">G_MARKUP_ERROR_UNKNOWN_ATTRIBUTE</code></span></p></td><td>error should be set by <a class="link" href="glib-Simple-XML-Subset-Parser.html#GMarkupParser"><span class="type">GMarkupParser</span></a> functions; attribute wasn't known</td></tr><tr><td><p><span class="term"><a name="G-MARKUP-ERROR-INVALID-CONTENT:CAPS"></a><code class="literal">G_MARKUP_ERROR_INVALID_CONTENT</code></span></p></td><td>error should be set by <a class="link" href="glib-Simple-XML-Subset-Parser.html#GMarkupParser"><span class="type">GMarkupParser</span></a> functions; content was invalid</td></tr><tr><td><p><span class="term"><a name="G-MARKUP-ERROR-MISSING-ATTRIBUTE:CAPS"></a><code class="literal">G_MARKUP_ERROR_MISSING_ATTRIBUTE</code></span></p></td><td>error should be set by <a class="link" href="glib-Simple-XML-Subset-Parser.html#GMarkupParser"><span class="type">GMarkupParser</span></a> functions; a required attribute was missing</td></tr></tbody></table></div></div><hr><div class="refsect2" lang="en"><a name="id3164972"></a><h3><a name="G-MARKUP-ERROR:CAPS"></a>G_MARKUP_ERROR</h3><a class="indexterm" name="id3164984"></a><pre class="programlisting">#define G_MARKUP_ERROR g_markup_error_quark ()</pre><p>Error domain for markup parsing.
