Functions

func Marshal 

func Marshal(d *Document) ([]byte, error)

Marshal returns the Netscape Bookmark encoding of d.

Example 
document := netscape.Document{
	Title: "Bookmarks",
	Root: netscape.Folder{
		Name: "Bookmarks",
		Bookmarks: []netscape.Bookmark{
			{
				URL:   "https://domain.tld",
				Title: "Test Domain",
			},
			{
				Description: "Local\nLocal\nLocal",
				URL:         "https://local.domain.tld",
				Title:       "Local Test Domain",
			},
		},
		Subfolders: []netscape.Folder{
			{
				Name: "Sub",
				Bookmarks: []netscape.Bookmark{
					{
						URL:   "https://domain.tld",
						Title: "Test Domain",
						Attributes: map[string]string{
							"ATTR1": "v1",
							"ATTR2": "42",
						},
					},
					{
						Description: "Local\nLocal\nLocal",
						URL:         "https://local.domain.tld",
						Title:       "Local Test Domain",
					},
				},
			},
		},
	},
}

m, err := netscape.Marshal(&document)
if err != nil {
	panic(err)
}

fmt.Print(string(m))

Output:

<!DOCTYPE NETSCAPE-Bookmark-file-1>
