microdata - a microdata parser in Go microdata - a microdata parser in Go
INSTALLATION
============
Simply run
go get github.com/iand/microdata
Documentation is at [http://go.pkgdoc.org/github.com/iand/microdata](http://go.pkgdoc.org/github.com/iand/microdata)
USAGE
=====
Example of parsing a string containing HTML:
include (
"net/url"
"strings"
)
html = `<div itemscope>
<p>My name is <span itemprop="name">Elizabeth</span>.</p>
</div>`
baseUrl, _ := url.Parse("http://example.com/")
p := NewParser(strings.NewReader(html), baseUrl)
data, err := p.Parse()
if err != nil {
t.Errorf("Expected no error but got %d", err)
}
println("Name: ", data.items[0].properties["name"][0]
