# Sanitize

sanitize :: Text -> Text #

Sanitize HTML to prevent XSS attacks. This is equivalent to `filterTags safeTags`.

sanitizeBalance :: Text -> Text #

Sanitize HTML to prevent XSS attacks and also make sure the tags are balanced. This is equivalent to `filterTags (balanceTags . safeTags)`.

sanitizeXSS :: Text -> Text #

alias of sanitize function

# Custom filtering

filterTags :: ([Tag Text] -> [Tag Text]) -> Text -> Text #

Parse the given text to a list of tags, apply the given filtering function, and render back to HTML. You can insert your own custom filtering but make sure you compose your filtering function with `safeTags`!

safeTags :: [Tag Text] -> [Tag Text] #

Filters out any usafe tags and attributes. Use with filterTags to create a custom filter.

balanceTags :: [Tag Text] -> [Tag Text] #

Filter which makes sure the tags are balanced. Use with `filterTags` and `safeTags` to create a custom filter.

# Utilities

safeTagName :: Text -> Bool #

sanitizeAttribute :: (Text, Text) -> Maybe (Text, Text) #

low-level API if you have your own HTML parser. Used by safeTags.

sanitaryURI :: Text -> Bool #

Returns `True` if the specified URI is not a potential security risk.
