Parse a XML from URL.

doc, err := xmlquery.LoadURL("http://www.example.com/sitemap.xml")

Parse a XML from string.

s := `<?xml version="1.0" encoding="utf-8"?><rss version="2.0"></rss>`
doc, err := xmlquery.Parse(strings.NewReader(s))

Parse a XML from io.Reader.

f, err := os.Open("../books.xml")
doc, err := xmlquery.Parse(f)

Find authors of all books in the bookstore.

list := xmlquery.Find(doc, "//book//author")
// or
list := xmlquery.Find(doc, "//author")

Find the second book.

book := xmlquery.FindOne(doc, "//book[2]")

Find all book elements and only get id attribute self. (New Feature)

list := xmlquery.Find(doc,"//book/@id")

Find all books with id is bk104.

list := xmlquery.Find(doc, "//book[@id='bk104']")

Find all books that price less than 5.

list := xmlquery.Find(doc, "//book[price<5]")

Evaluate the total price of all books.

expr, err := xpath.Compile("sum(//book/price)")
price := expr.Evaluate(xmlquery.CreateXPathNavigator(doc)).(float64)
fmt.Printf("total price: %f\n", price)

Evaluate the number of all books element.

expr, err := xpath.Compile("count(//book)")
price := expr.Evaluate(xmlquery.CreateXPathNavigator(doc)).(float64)

Create XML document.

doc := &xmlquery.Node{
	Type: xmlquery.DeclarationNode,
	Data: "xml",
	Attr: []xml.Attr{
		xml.Attr{Name: xml.Name{Local: "version"}, Value: "1.0"},
root := &xmlquery.Node{
	Data: "rss",
	Type: xmlquery.ElementNode,
doc.FirstChild = root
channel := &xmlquery.Node{
	Data: "channel",
	Type: xmlquery.ElementNode,
root.FirstChild = channel
title := &xmlquery.Node{
	Data: "title",
	Type: xmlquery.ElementNode,
title_text := &xmlquery.Node{
	Data: "W3Schools Home Page",
	Type: xmlquery.TextNode,
title.FirstChild = title_text
channel.FirstChild = title
// <?xml version="1.0"?><rss><channel><title>W3Schools Home Page</title></channel></rss>

	doc, err := Parse(strings.NewReader(s))
	if err != nil {
	channel := FindOne(doc, "//channel")
	fmt.Printf("title: %s\n", channel.SelectElement("title").InnerText())
	fmt.Printf("link: %s\n", channel.SelectElement("link").InnerText())
	for i, n := range Find(doc, "//item") {
		fmt.Printf("#%d %s\n", i, n.SelectElement("title"))
