swifthtml数据解析，在swift中解析html的最佳做法是什么？有⼏个很好的HTML解析库，使⽤Swift和Objective-C，如下所⽰：
看看下⾯的例⼦，在上⾯发布的四个图书馆⾥，主要使⽤XPath 2.0进⾏解析：
hpple:
let data = NSData(contentsOfFile: path)
let doc = TFHpple(HTMLData: data)
if let elements = doc.searchWithXPathQuery("//a/@href[ends-with(.,'.txt')]") as? [TFHppleElement] {
for element in elements {
t)
}
}
NDHpple:
let data = NSData(contentsOfFile: path)!
let html = NSString(data: data, encoding: NSUTF8StringEncoding)!
let doc = NDHpple(HTMLData: html)
if let elements = doc.searchWithXPathQuery("//a/@href[ends-with(.,'.txt')]") {
for element in elements {
println(element.children?.first?.content)
}
}
Kanna (Xpath and CSS Selectors):
let html = "
Hello World 1 Hello World 2
Hello World 2 "
if let doc = Kanna.HTML(html: html, encoding: NSUTF8StringEncoding) {
var bodyNode = doc.body
if let inputNodes = bodyNode?.xpath("//a/@href[ends-with(.,'.txt')]") {
for node in inputNodes {
ts)
}
}
}
html document是什么Fuzi (Xpath and CSS Selectors):
let html = "
Hello World 2 "
Hello World 1 Hello World 2
do {
// if encoding is omitted, it defaults to NSUTF8StringEncoding
let doc = try HTMLDocument(string: html, encoding: NSUTF8StringEncoding) // XPath queries
for anchor in doc.xpath("//a/@href[ends-with(.,'.txt')]") {
print(anchor.stringValue)
}
} catch let error {
print(error)
}
结束功能是Xpath 2.0的⼀部分。
我希望这能帮助你。
