SwiftyExpat 是简单的 Expat XML Parser
的封装，可以使用块，而不用函数指针调用。
SwiftyExpat 包括两个部分：
-
SwiftyExpat
-
SwiftyExpatTests
let p = Expat()
.onStartElement { name, attrs in println("<\(name) \(attrs)") }
.onEndElement { name in println(">\(name)") }
.onStartNamespace { prefix, uri in println("+NS[\(prefix)] = \(uri)") }
.onEndNamespace { prefix in println("-NS[\(prefix)]") }
.onError { error in println("ERROR: \(error)") }p.write("<hello>world</hello>")p.close()
Expat API 示例：
var p = XML_ParserCreate("UTF-8")
XML_SetStartElementHandler(p) { _, name, attrs in println("start tag \(name)") }
XML_SetEndElementHandler (p) { _, name in println("end tag \(name)") }
XML_Parse(parser, "<hello/>", 8, 0)XML_Parse(parser, "", 0, 1)
XML_ParserFree(p); p = nil
