HELLO '); // becomes
+DOMPurify.sanitize(''); // becomes
+```
+
+## What is supported?
+
+DOMPurify currently supports HTML5, SVG and MathML. DOMPurify per default allows CSS, HTML custom data attributes. DOMPurify also supports the Shadow DOM - and sanitizes DOM templates recursively. DOMPurify also allows you to sanitize HTML for being used with the jQuery `$()` and `elm.html()` API without any known problems.
+
+## What about legacy browsers like Internet Explorer?
+
+DOMPurify does nothing at all. It simply returns exactly the string that you fed it. DOMPurify exposes a property called `isSupported`, which tells you whether it will be able to do its job, so you can come up with your own backup plan.
+
+## What about DOMPurify and Trusted Types?
+
+In version 1.0.9, support for [Trusted Types API](https://github.com/w3c/webappsec-trusted-types) was added to DOMPurify.
+In version 2.0.0, a config flag was added to control DOMPurify's behavior regarding this.
+
+When `DOMPurify.sanitize` is used in an environment where the Trusted Types API is available and `RETURN_TRUSTED_TYPE` is set to `true`, it tries to return a `TrustedHTML` value instead of a string (the behavior for `RETURN_DOM` and `RETURN_DOM_FRAGMENT` config options does not change).
+
+Note that in order to create a policy in `trustedTypes` using DOMPurify, `RETURN_TRUSTED_TYPE: false` is required, as `createHTML` expects a normal string, not `TrustedHTML`. The example below shows this.
+
+```js
+window.trustedTypes!.createPolicy('default', {
+ createHTML: (to_escape) =>
+ DOMPurify.sanitize(to_escape, { RETURN_TRUSTED_TYPE: false }),
+});
+```
+
+## Can I configure DOMPurify?
+
+Yes. The included default configuration values are pretty good already - but you can of course override them. Check out the [`/demos`](https://github.com/cure53/DOMPurify/tree/main/demos) folder to see a bunch of examples on how you can [customize DOMPurify](https://github.com/cure53/DOMPurify/tree/main/demos#what-is-this).

+### General settings
+```js
+// strip {{ ... }}, ${ ... } and <% ... %> to make output safe for template systems
+// be careful please, this mode is not recommended for production usage.
+// allowing template parsing in user-controlled HTML is not advised at all.
+// only use this mode if there is really no alternative.
+const clean = DOMPurify.sanitize(dirty, {SAFE_FOR_TEMPLATES: true});
+
+
+// change how e.g. comments containing risky HTML characters are treated.
+// be very careful, this setting should only be set to `false` if you really only handle
+// HTML and nothing else, no SVG, MathML or the like.
+// Otherwise, changing from `true` to `false` will lead to XSS in this or some other way.
+const clean = DOMPurify.sanitize(dirty, {SAFE_FOR_XML: false});
+```
+
+### Control our allow-lists and block-lists
+```js
+// allow only elements, very strict
+const clean = DOMPurify.sanitize(dirty, {ALLOWED_TAGS: ['b']});
+
+// allow only and with style attributes
+const clean = DOMPurify.sanitize(dirty, {ALLOWED_TAGS: ['b', 'q'], ALLOWED_ATTR: ['style']});
+
+// allow all safe HTML elements but neither SVG nor MathML
+// note that the USE_PROFILES setting will override the ALLOWED_TAGS setting
+// so don't use them together

+
+// allow all safe SVG elements and SVG Filters, no HTML or MathML
+const clean = DOMPurify.sanitize(dirty, {USE_PROFILES: {svg: true, svgFilters: true}});
+
+// allow all safe MathML elements and SVG, but no SVG Filters
+const clean = DOMPurify.sanitize(dirty, {USE_PROFILES: {mathMl: true, svg: true}});
+
+// change the default namespace from HTML to something different
+const clean = DOMPurify.sanitize(dirty, {NAMESPACE: 'http://www.w3.org/2000/svg'});
+
+// leave all safe HTML as it is and add Some text';
+
+ $config = HTMLPurifier_Config::createDefault();
+ $config->set('Filter', 'ExtractStyleBlocks', true);
+ $purifier = new HTMLPurifier($config);
+
+ $html = $purifier->purify($dirty);
+
+ // This implementation writes the stylesheets to the styles/ directory.
+ // You can also echo the styles inside the document, but it's a bit
+ // more difficult to make sure they get interpreted properly by
+ // browsers; try the usual CSS armoring techniques.

+
+ Warning: It is possible for a user to mount an
+ imagecrash attack using this CSS. Counter-measures are difficult;
+ it is not simply enough to limit the range of CSS lengths (using
+ relative lengths with many nesting levels allows for large values
+ to be attained without actually specifying them in the stylesheet),
+ and the flexible nature of selectors makes it difficult to selectively
+ disable lengths on image tags (HTML Purifier, however, does disable
+ CSS width and height in inline styling). There are probably two effective
+ counter measures: an explicit width and height set to auto in all
+ images in your document (unlikely) or the disabling of width and
+ height (somewhat reasonable). Whether or not these measures should be
+ used is left to the reader.

+ Defines the domain name of the server, so we can determine whether or

+ subdomains of the domain you post here: i.e. example.com will allow
+ sub.example.com. However, higher up domains will still be excluded:
+ if you set %URI.Host to sub.example.com, example.com will be blocked.
+ Note: This directive overrides %URI.Base because
+ a given page may be on a sub-domain, but you wish HTML Purifier to be
+ more relaxed and allow some of the parent domains too.

+URI.Munge
+TYPE: string/null
+VERSION: 1.3.0
+DEFAULT: NULL
+--DESCRIPTION--
+
+
+ Munges all browsable (usually http, https and ftp)
+ absolute URIs into another URI, usually a URI redirection service.
+ This directive accepts a URI, formatted with a %s where
+ the url-encoded original URI should be inserted (sample:
+ http://www.google.com/url?q=%s).
+
+
+ Uses for this directive:
+
+
+
+ Prevent PageRank leaks, while being fairly transparent
+ to users (you may also want to add some client side JavaScript to
+ override the text in the statusbar). Notice :
+ Many security experts believe that this form of protection does not deter spam-bots.
+
+
+ Redirect users to a splash page telling them they are leaving your
+ website. While this is poor usability practice, it is often mandated
+ in corporate environments.
+
+
+
+ Prior to HTML Purifier 3.1.1, this directive also enabled the munging
+ of browsable external resources, which could break things if your redirection
+ script was a splash page or used meta tags. To revert to
+ previous behavior, please use %URI.MungeResources.
+
+
+ You may want to also use %URI.MungeSecretKey along with this directive
+ in order to enforce what URIs your redirector script allows. Open
+ redirector scripts can be a security risk and negatively affect the
+ reputation of your domain name.
+
+
+ Starting with HTML Purifier 3.1.1, there is also these substitutions:
+
+
+
+
+ Key
+ Description
+ Example <a href="">
+
+
+
+
+ %r
+ 1 - The URI embeds a resource (blank) - The URI is merely a link
+
+
+
+ %n
+ The name of the tag this URI came from
+ a
+
+
+ %m
+ The name of the attribute this URI came from
+ href
+
+
+ %p
+ The name of the CSS property this URI came from, or blank if irrelevant
+
+
+
+
+
+ Admittedly, these letters are somewhat arbitrary; the only stipulation
+ was that they couldn't be a through f. r is for resource (I would have preferred
+ e, but you take what you can get), n is for name, m
+ was picked because it came after n (and I couldn't use a), p is for
+ property.

+URI.MungeSecretKey
+TYPE: string/null
+VERSION: 3.1.1
+DEFAULT: NULL
+--DESCRIPTION--
+
+ This directive enables secure checksum generation along with %URI.Munge.
+ It should be set to a secure key that is not shared with anyone else.
+ The checksum can be placed in the URI using %t. Use of this checksum
+ affords an additional level of protection by allowing a redirector
+ to check if a URI has passed through HTML Purifier with this line:
+
+
+$checksum === hash_hmac("sha256", $url, $secret_key)
+
+
+ If the output is TRUE, the redirector script should accept the URI.
+
+
+
+ Please note that it would still be possible for an attacker to procure
+ secure hashes en-mass by abusing your website's Preview feature or the
+ like, but this service affords an additional level of protection
+ that should be combined with website blacklisting.
+
+
+
+ Remember this has no effect if %URI.Munge is not on.

+// Note [Injector skips]
+// ~~~~~~~~~~~~~~~~~~~~~
+// When I originally designed this class, the idea behind the 'skip'
+// property of HTMLPurifier_Token was to help avoid infinite loops
+// in injector processing. For example, suppose you wrote an injector
+// that bolded swear words. Naively, you might write it so that
+// whenever you saw ****, you replaced it with
**** .
+//
+// When this happens, we will reprocess all of the tokens with the
+// other injectors. Now there is an opportunity for infinite loop:
+// if we rerun the swear-word injector on these tokens, we might
+// see **** and then reprocess again to get
+//
**** ad infinitum.
+//
+// Thus, the idea of a skip is that once we process a token with
+// an injector, we mark all of those tokens as having "come from"
+// the injector, and we never run the injector again on these
+// tokens.
+//
+// There were two more complications, however:
+//
+// - With HTMLPurifier_Injector_RemoveEmpty, we noticed that if
+// you had
, after you removed the
, you
+// really would like this injector to go back and reprocess
+// the
tag, discovering that it is now empty and can be
+// removed. So we reintroduced the possibility of infinite looping
+// by adding a "rewind" function, which let you go back to an
+// earlier point in the token stream and reprocess it with injectors.
+// Needless to say, we need to UN-skip the token so it gets
+// reprocessed.
+//
+// - Suppose that you successfully process a token, replace it with
+// one with your skip mark, but now another injector wants to
+// process the skipped token with another token. Should you continue
+// to skip that new token, or reprocess it? If you reprocess,
+// you can end up with an infinite loop where one injector converts
+// to , and then another injector converts it back. So
+// we inherit the skips, but for some reason, I thought that we
+// should inherit the skip from the first token of the token
+// that we deleted. Why? Well, it seems to work OK.
+//
+// If I were to redesign this functionality, I would absolutely not
+// go about doing it this way: the semantics are just not very well
+// defined, and in any case you probably wanted to operate on trees,
+// not token streams.
