let titleNode = jiDoc?.xPath("//head/title")?.first
print("title: \(String(describing: titleNode?.content))") // title: Optional("Official Apple Support")

let xmlString = "<?xml version='1.0' encoding='UTF-8'?><note><to>Tove</to><from>Jani</from><heading>Reminder</heading><body>Don't forget me this weekend!</body></note>"
let jiDoc = Ji(xmlString: xmlString)
let bodyNode = jiDoc?.rootNode?.firstChildWithName("body")
print("body: \(String(describing: bodyNode?.content))") // body: Optional("Don\'t forget me this weekend!")

Init with Data:

let googleIndexData = try? Data(contentsOf: URL(string: "http://www.google.com")!)
if let googleIndexData = googleIndexData {
    let jiDoc = Ji(htmlData: googleIndexData)!
    let htmlNode = jiDoc.rootNode!
    print("html tagName: \(String(describing: htmlNode.tagName))") // html tagName: Optional("html")

    let aNodes = jiDoc.xPath("//body//a")
    if let firstANode = aNodes?.first {
        print("first a node tagName: \(String(describing: firstANode.name))") // first a node tagName: Optional("a")
        let href = firstANode["href"]
        print("first a node href: \(String(describing: href))") // first a node href: Optional("http://www.google.ca/imghp?hl=en&tab=wi")
    }
} else {
    print("google.com is inaccessible")
