| * Sanitizes an html string by stripping all potentially dangerous tokens. |

| * |
| * The whitelist for URL sanitization of attribute values is configured using the functions |
| * `aHrefSanitizationWhitelist` and `imgSrcSanitizationWhitelist` of {@link ng.$compileProvider |
| * `$compileProvider`}. |
| * |
| * The input may also contain SVG markup if this is enabled via {@link $sanitizeProvider}. |
