Text.HTML.Basic.Tag

We do not define a tag data type here, since this is too much bound to the particular use (e.g. list or tree structure). However we define a tag name and several

Methods

(==) :: Name ident -> Name ident -> Bool

(/=) :: Name ident -> Name ident -> Bool

Methods

compare :: Name ident -> Name ident -> Ordering

(<) :: Name ident -> Name ident -> Bool

(<=) :: Name ident -> Name ident -> Bool

(>) :: Name ident -> Name ident -> Bool

(>=) :: Name ident -> Name ident -> Bool

max :: Name ident -> Name ident -> Name ident

min :: Name ident -> Name ident -> Name ident

Show ident => Show (Name ident)

Methods

showsPrec :: Int -> Name ident -> ShowS

show :: Name ident -> String

showList :: [Name ident] -> ShowS

Tag ident => C (Name ident)

Defined in Text.XML.Basic.Tag

Methods

fromString :: String -> Name ident

toString :: Name ident -> String

doctype :: Tag name => Name name

Deprecated: use doctypeName instead

doctypeName :: Tag name => Name name

doctypeString :: String

cdata :: Tag name => Name name

Deprecated: use cdataName instead

cdataName :: Tag name => Name name

cdataString :: String

isEmpty :: Tag name => Name name -> Bool

Check whether a HTML tag is empty.

isSloppy :: Tag name => Name name -> Bool

Some tags, namely those for text styles like FONT, B, I, are used quite sloppily. That is, they are not terminated or not terminated in the right order. We close them implicitly, if another tag closes and ignore non-matching closing tags.

isInnerOf :: Tag name => Name name -> Name name -> Bool

closes :: Tag name => Name name -> Name name -> Bool

maybeMetaHTTPHeader :: (Tag name, Attribute name) => Name name -> [T name string] -> Maybe (string, string)

maybeMetaEncoding :: (Tag name, Attribute name) => Name name -> [T name String] -> Maybe String

A simple routine that does not check for valid syntax of the Content-Type specification.

In future we might use a distinct Encoding type instead of plain String.

maybeMetaCharset :: (Tag name, Attribute name) => Name name -> [T name string] -> Maybe string

encodingFromContentType :: String -> String

Extract charset from Content-Type declaration.

encodingFromContentType "text/html; charset=UTF-8" == "utf-8"

The routine does not perform any syntax check.
