+Package html implements an HTML5-compliant tokenizer and parser.
+INCOMPLETE.
+
+Tokenization is done by creating a Tokenizer for an io.Reader r. It is the
+caller's responsibility to ensure that r provides UTF-8 encoded HTML.
+
+ z := html.NewTokenizer(r)
+
+Given a Tokenizer z, the HTML is tokenized by repeatedly calling z.Next(),
+which parses the next token and returns its type, or an error:
+
+ for {
+ tt := z.Next()
+ if tt == html.ErrorToken {
+ // ...
+ return ...
+ }
+ // Process the current token.
+ }
+
+There are two APIs for retrieving the current token. The high-level API is to
+call Token; the low-level API is to call Text or TagName / TagAttr. Both APIs
+allow optionally calling Raw after Next but before Token, Text, TagName, or
+TagAttr. In EBNF notation, the valid call sequence per token is:
+
+ Next {Raw} [ Token | Text | TagName {TagAttr} ]
+
+Token returns an independent data structure that completely describes a token.
+Entities (such as "<") are unescaped, tag names and attribute keys are
+lower-cased, and attributes are collected into a []Attribute. For example:
+
+ for {
+ if z.Next() == html.ErrorToken {
+ // Returning io.EOF indicates success.
+ return z.Err()
+ }
+ emitToken(z.Token())
+ }
+
+The low-level API performs fewer allocations and copies, but the contents of
+the []byte values returned by Text, TagName and TagAttr may change on the next
+call to Next. For example, to extract an HTML page's anchor text:
+
+ depth := 0
+ for {
+ tt := z.Next()
+ switch tt {
+ case ErrorToken:
+ return z.Err()
+ case TextToken:
+ if depth > 0 {
+ // emitBytes should copy the []byte it receives,
+ // if it doesn't process it immediately.
+ emitBytes(z.Text())
+ }
+ case StartTagToken, EndTagToken:
+ tn, _ := z.TagName()
+ if len(tn) == 1 && tn[0] == 'a' {
+ if tt == StartTagToken {
+ depth++
+ } else {
+ depth--
+ }
+ }
+ }
+ }
+
+Parsing is done by calling Parse with an io.Reader, which returns the root of
+the parse tree (the document element) as a *Node. It is the caller's
+responsibility to ensure that the Reader provides UTF-8 encoded HTML. For
+example, to process each anchor node in depth-first order:
+
+ doc, err := html.Parse(r)
+ if err != nil {
+ // ...
+ }
+ var f func(*html.Node)
+ f = func(n *html.Node) {
+ if n.Type == html.ElementNode && n.Data == "a" {
+ // Do something with n...
+ }
+ for _, c := range n.Child {
+ f(c)
+ }
+ }
+ f(doc)
+
+The relevant specifications include:
+http://www.whatwg.org/specs/web-apps/current-work/multipage/syntax.html and
+http://www.whatwg.org/specs/web-apps/current-work/multipage/tokenization.html
+*/
+package html
+
+// The tokenization algorithm implemented by this package is not a line-by-line
+// transliteration of the relatively verbose state-machine in the WHATWG
+// specification. A more direct approach is used instead, where the program
+// counter implies the state, such as whether it is tokenizing a tag or a text
+// node. Specification compliance is verified by checking expected and actual
+// outputs over a test suite rather than aiming for algorithmic fidelity.
+
+// TODO(nigeltao): Does a DOM API belong in this package or a separate one?
+// TODO(nigeltao): How does parsing interact with a JavaScript engine?
