Synopsis:

import Kanna  let html = "<html>...</html>"  if let doc = Kanna.HTML(html: html, encoding: NSUTF8StringEncoding) {     print(doc.title)      // Search for nodes by CSS     for link in doc.css("a, link") {         print(link.text)         print(link["href"])     }      // Search for nodes by XPath     for link in doc.xpath("//a | //link") {         print(link.text)         print(link["href"])     } }

let xml = "..." if let doc = Kanna.XML(xml: xml, encoding: NSUTF8StringEncoding) {     let namespaces = [                     "o":  "urn:schemas-microsoft-com:office:office",                     "ss": "urn:schemas-microsoft-com:office:spreadsheet"                 ]     if let author = doc.at_xpath("//o:Author", namespaces: namespaces) {         print(author.text)     } }
