- 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 {
