# MyHTML — a pure C HTML parser
[](https://travis-ci.org/lexborisov/myhtml)
MyHTML is a fast HTML Parser using Threads implemented as a pure C99 library with no outside dependencies.
## Now
### Important announcement!
Please use the HTML parser from the [Lexbor project](https://github.com/lexbor/lexbor). It is stable, has more features, and — yes — it's very fast.
## Features
- Asynchronous Parsing, Build Tree and Indexation
- Fully conformant with the [HTML5 specification]
- Two API - [high] and [low]-level
- Manipulation of elements: add, change, delete and other
- Manipulation of elements attributes: add, change, delete and other
- Support 39 character encoding by specification [encoding.spec.whatwg.org]
- Support detecting character encodings
- Support Single Mode parsing
- Support Build without POSIX Threads
- Support for fragment parsing
- Support for [parsing by chunks]
- No outside dependencies
- C99 support
- Passes all tree construction tests from [html5lib-tests]
- Tested by 1 billion HTML pages (by [commoncrawl.org])
## Changes
Please, see [CHANGELOG.md] file
## Further developments
- [Modest] — Modest is a fast HTML Render implemented as a pure C99 library with no outside dependencies
- [MyCSS] — Fast C/C++ CSS Parser (Cascading Style Sheets Parser)
## Support encodings for InputStream
```text
X_USER_DEFINED, UTF_8, UTF_16LE, UTF_16BE, BIG5, EUC_KR, GB18030,
IBM866, ISO_8859_10, ISO_8859_13, ISO_8859_14, ISO_8859_15, ISO_8859_16, ISO_8859_2, ISO_8859_3,
ISO_8859_4, ISO_8859_5, ISO_8859_6, ISO_8859_7, ISO_8859_8, KOI8_R, KOI8_U, MACINTOSH,
WINDOWS_1250, WINDOWS_1251, WINDOWS_1252, WINDOWS_1253, WINDOWS_1254, WINDOWS_1255, WINDOWS_1256,
WINDOWS_1257, WINDOWS_1258, WINDOWS_874, X_MAC_CYRILLIC, ISO_2022_JP, GBK, SHIFT_JIS, EUC_JP, ISO_8859_8_I
```
## Support encodings for output
**Program working in UTF-8 and returns all in UTF-8**
## Detecting character encodings
Now it UTF-8, UTF-16LE, UTF16BE and russian windows-1251, koi8-r, iso-8859-5, x-mac-cyrillic, ibm866

char html[] = "
HTML";
// 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;
