xml的用处越来越广泛了,解析xml得库也非常多,总的来说分为两种,一种是把xml当作一个“树”来进行解析,一种是基于事件类型的
glib就是使用事件类型解析xml。
#include stdio.h>
gchar *current_animal_noise = NULL;
static void start(GMarkupParseContext *context,
const gchar *element_name,
const gchar **attribute_names,
const gchar **attribute_values,
gpointer user_data,
GError **error)
{
const gchar **name_cursor = attribute_names;
const gchar **value_cursor = attribute_values;
while (*name_cursor) {
if (strcmp (*name_cursor, "noise") == 0)
current_animal_noise = g_strdup (*value_cursor);
name_cursor++;
value_cursor++;
}
}
static void end(GMarkupParseContext *context,
const gchar *element_name,
gpointer user_data,
GError **error)
{
if (current_animal_noise)
{
g_free (current_animal_noise);
current_animal_noise = NULL;
}
}
static void text(GMarkupParseContext *context,
const gchar *text,
gsize text_len,
gpointer user_data,
GError **error)
{
if (current_animal_noise)
printf("I am a %*s and I go %s. Can you do it?/n",
text_len, text, current_animal_noise);
printf("test text/n");
}
GMarkupParser parser = {
.start_element = start,
.end_element = end,
.text = text,
.passthrough = NULL,
.error = NULL
};
int main()
{
char *buf;
gsize length;
GMarkupParseContext *context;
g_file_get_contents("test.xml", &buf, &length,NULL);
g_printf("%s/n",buf);
context = g_markup_parse_context_new(&parser, 0, NULL, NULL);
if (g_markup_parse_context_parse(context, buf, length, NULL) == FALSE)
{
printf("Couldn't load xml/n");
g_markup_parse_context_free(context);
return 0;
}
