Simple example
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <myhtml/api.h>
int main(int argc, const char * argv[])
{
char html[] = "<div><span>HTML</span></div>";
// basic init
myhtml_t* myhtml = myhtml_create();
myhtml_init(myhtml, MyHTML_OPTIONS_DEFAULT, 1, 0);
// first tree init
myhtml_tree_t* tree = myhtml_tree_create();
myhtml_tree_init(tree, myhtml);
// parse html
myhtml_parse(tree, MyENCODING_UTF_8, html, strlen(html));
// print result
// or see serialization function with callback: myhtml_serialization_tree_callback
mycore_string_raw_t str = {0};
myhtml_serialization_tree_buffer(myhtml_tree_get_document(tree), &str);
printf("%s\n", str.data);
// release resources
mycore_string_raw_destroy(&str, false);
myhtml_tree_destroy(tree);
myhtml_destroy(myhtml);
return 0;
