Crate html_escape

Expand description

§HTML Escape

This library is for encoding/escaping special characters in HTML and decoding/unescaping HTML entities as well.

§Usage

§Encoding

This crate provides some encode_* functions to encode HTML text in different situations.

For example, to put a text between a start tag <foo> and an end tag </foo>, use the encode_text function to escape every &, <, and > in the text.

assert_eq!("a &gt; b &amp;&amp; a &lt; c", html_escape::encode_text("a > b && a < c"));

The functions suffixed with _to_writer, _to_vec or _to_string are useful to generate HTML.

let mut html = String::from("<input value=");
assert_eq!("Hello&#x20;world&#x21;", html_escape::encode_unquoted_attribute_to_string("Hello world!", &mut html));
html.push_str(" placeholder=\"");
assert_eq!("The default value is &quot;Hello world!&quot;.", html_escape::encode_double_quoted_attribute_to_string("The default value is \"Hello world!\".", &mut html));
html.push_str("\"/><script>alert('");
assert_eq!(r"<script>\'s end tag is <\/script>", html_escape::encode_script_single_quoted_text_to_string("<script>'s end tag is </script>", &mut html));
html.push_str("');</script>");

assert_eq!("<input value=Hello&#x20;world&#x21; placeholder=\"The default value is &quot;Hello world!&quot;.\"/><script>alert(\'<script>\\\'s end tag is <\\/script>\');</script>", html);

§Decoding

assert_eq!("Hello world!", html_escape::decode_html_entities("Hello&#x20;world&#x21;"));

assert_eq!("alert('<script></script>');", html_escape::decode_script(r"alert('<script><\/script>');"));
