+Package html implements an HTML5-compliant tokenizer and parser.
+
+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 html.ErrorToken:
+ return z.Err()
+ case html.TextToken:
+ if depth > 0 {
+ // emitBytes should copy the []byte it receives,
+ // if it doesn't process it immediately.
+ emitBytes(z.Text())
+ }
+ case html.StartTagToken, html.EndTagToken:
+ tn, _ := z.TagName()
+ if len(tn) == 1 && tn[0] == 'a' {
+ if tt == html.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 := n.FirstChild; c != nil; c = c.NextSibling {
+ f(c)
+ }
+ }
+ f(doc)
+

+https://html.spec.whatwg.org/multipage/syntax.html and
+https://html.spec.whatwg.org/multipage/syntax.html#tokenization
+*/
+package html // import "golang.org/x/net/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.

+// Calling Parse on arbitrary input typically results in a 'well-formed' parse
+// tree. However, it is possible for Parse to yield a 'badly-formed' parse tree.

+// Similarly, in a 'well-formed' parse tree, no <a> element is a child of a

+* The client work has just started but shares a lot of code
+ is coming along much quicker.

+Package trace implements tracing of requests and long-lived objects.
+It exports HTTP interfaces on /debug/requests and /debug/events.
+
+A trace.Trace provides tracing for short-lived objects, usually requests.
+A request handler might be implemented like this:
+
+ func fooHandler(w http.ResponseWriter, req *http.Request) {
+ tr := trace.New("mypkg.Foo", req.URL.Path)
+ defer tr.Finish()
+ ...
+ tr.LazyPrintf("some event %q happened", str)
+ ...
+ if err := somethingImportant(); err != nil {
+ tr.LazyPrintf("somethingImportant failed: %v", err)
+ tr.SetError()
+ }
+ }
+
+The /debug/requests HTTP endpoint organizes the traces by family,
+errors, and duration. It also provides histogram of request duration
+for each family.
+
+A trace.EventLog provides tracing for long-lived objects, such as RPC
+connections.
+
+ // A Fetcher fetches URL paths for a single domain.
+ type Fetcher struct {
+ domain string
+ events trace.EventLog
+ }

+ func NewFetcher(domain string) *Fetcher {

+ }
+ f.events.Printf("Get(%q) = %s", path, resp.Status)
+ ...
+ }
+
+ func (f *Fetcher) Close() error {
+ f.events.Finish()
+ return nil
+ }
+
+The /debug/events HTTP endpoint organizes the event logs by family and
+by time since the last error. The expanded view displays recent log
+entries and the log's call stack.
