Gunslinger XML

A lightweight XML parser for use with Gunslinger.

At the moment, this library is capable of parsing the following document:

<?xml version="1.0" encoding="UTF-8"?>
<test some_attrib="I'm an attribute!" some_entities="&apos; &amp; &quot; &lt; &gt;" some_number1  =     "384.7" some_bool="true">
	<test_child>Hello, world!</test_child>
	<other_test_child some_bool="false">
		<other_test_child_child>Hello there! &apos; &amp; &quot; &lt; &gt;</other_test_child_child>
	</other_test_child>

	<!-- Hello, I'm a comment. -->

	<some_thing thing="Haha yes" thing1 = "33"/>

	<!-- I'm another comment. -->
</test>

It supports the following entities:

Character	Entity
&	`&`
'	`'`
"	`"`
<	`<`
>	`>`

Usage

Before use, make sure you have Gunslinger set up, including adding gs.h, from the Gunslinger repository to your include path. Then, #define GS_XML_IMPL in one C or C++ source file before you #include gs_xml.h.

Basic Usage

// To parse from memory: gs_xml_parse(const char* source)
gs_xml_document_t* doc = gs_xml_parse_file("./test.xml");
if (!doc)
{
	printf("XML Parse Error: %s\n", gs_xml_get_error());
	return;
}

gs_xml_free(doc);

Examples

A more complete example can be found in example.

Finding Elements

// To find an element that isn't a child
gs_xml_node_t* node = gs_xml_find_node(doc, "test_node");

// To find a child
gs_xml_node_t* child = gs_xml_find_node_child(node, "test_child");

// To find an attribute
gs_xml_attribute_t* attrib = gs_xml_find_attribute(node, "test_attrib");

Getting the Name of Nodes

printf("%s\n", node->name);

Getting the Name & Value of attributes

printf("%s\n", attrib->name);

printf("%g\n", number_attrib->value.number);
printf("%s\n", string_attrib->value.string);
printf("%s\n", boolean_attrib->value.boolean ? "true" : "false");
