microformats
microformats is a go library and tool for parsing microformats, supporting both classic v1 and v2 syntax. It is based on Andy Leap's original library.
Usage
To see this package in action, the simplest way is to install the command line app and use it to fetch and parse a webpage with microformats on it:
% go install willnorris.com/go/microformats/cmd/gomf@latest % gomf https://indieweb.org To use it in your own code, import the package:
import "willnorris.com/go/microformats" If you have the HTML contents of a page in an io.Reader, call Parse like in this example:
content := `<article class="h-entry"><h1 class="p-name">Hello</h1></article>` r := strings.NewReader(content) data := microformats.Parse(r, nil) // do something with data, or just print it out as JSON: enc := json.NewEncoder(os.Stdout) enc.SetIndent("", " ") enc.Encode(data) Alternately, if you have already parsed the page and have an html.Node, then call ParseNode. For example, you might want to select a subset of the DOM, and parse only that for microformats. An example of doing this with the goquery package can be seen in cmd/gomf/main.go.
To see that in action using the gomf app installed above, you can parse the microformats from indieweb.org that appear within the #content element:
% gomf https://indieweb.org "#content" { "items": [ { "id": "content", "type": [ "h-entry" ], "properties": ... "children": ... } ], "rels": {}, "rel-urls": {} }

Overview ¶
Package microformats provides a microformats parser, supporting both v1 and v2 syntax.
Usage:
import "willnorris.com/go/microformats"
Retrieve the HTML contents of a page, and call Parse or ParseNode, depending on what input you have (an io.Reader or an html.Node).
To parse only a section of an HTML document, use a package like goquery to select the root node to parse from. For example, see cmd/gomf/main.go.

Types ¶
type Data ¶
type Data struct { // Items includes all top-level microformats found on the page. Items []*Microformat `json:"items"` // Rels includes all related URLs found on the page (<a> or <link> // elements with a "rel" value). Map keys are the rel value, mapped to // a slice of URLs with that relation. For example: // // map[string][]string{ // "author": {"http://example.com/a", "http://example.com/b"}, // "alternate": {"http://example.com/fr"}, // } // // Relative URL values are resolved to absolute URLs using the base URL // of the page. Rels map[string][]string `json:"rels"` // RelURLs maps related URLs found on the page to additional metadata // about that relationship. If a URL is linked to more than once, only // the metadata for the first link is included here. Relative URL // values are resolved to absolute URLs using the base URL of the page. RelURLs map[string]*RelURL `json:"rel-urls"` } Data specifies all of the microformats and data parsed from a single HTML page.
func Parse ¶
Parse the microformats found in the HTML document read from r. baseURL is the URL this document was retrieved from and is used to expand any relative URLs. If baseURL is nil and the base URL is not referenced in the document, relative URLs are not expanded.
type Microformat ¶
type Microformat struct { ID string `json:"id,omitempty"` Value string `json:"value,omitempty"` HTML string `json:"html,omitempty"` Type []string `json:"type"` Properties map[string][]any `json:"properties"` Shape string `json:"shape,omitempty"` Coords string `json:"coords,omitempty"` Children []*Microformat `json:"children,omitempty"` // contains filtered or unexported fields } Microformat specifies a single microformat object and its properties. It may represent a person, an address, a blog post, etc.
type RelURL ¶
type RelURL struct { Rels []string `json:"rels,omitempty"` Text string `json:"text,omitempty"` Media string `json:"media,omitempty"` HrefLang string `json:"hreflang,omitempty"` Title string `json:"title,omitempty"` Type string `json:"type,omitempty"` } RelURL represents the attributes of a URL. The URL value itself is the map key in the RelURLs field of the Data type.
