woodyHTML 解析/提取器

woody 是一款基于 Java 的 HTML 解析/提取器，用法非常类似 webmagic，是对其抽取模块的完全重写。

功能：

• 多种结果数据类型（String, char, byte, short int, long, double, float, string[], Set, List,Data）


• 支持用户之定义脚本处理函数（目前支持 Javascript 函数配置处理）


• 支持 css、xpath 内核替换


• 支持 filter 功能


• 对 css、xpath 内核对象的缓存

一个完整的例子：

public class OsChinaBlog {



	public static void main(String[] args) throws Exception {

		Document doc = Jsoup.connect("http://www.oschina.net/news/43879/webmagic-0-3-0").timeout(60000)

				.userAgent("Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:23.0) Gecko/20100101 Firefox/23.0").get();

		String html = doc.html();

		OsChinaBlogModel model = AnnotationExtractor.me().process(html, OsChinaBlogModel.class);

		System.out.println(model.toJson());

	}



	public static class OsChinaBlogModel extends Model {



		public OsChinaBlogModel() {

			//use to reflect

		}



		@Inject

		@ComboExtract(value = { @ExtractBy(value = "h1.OSCTitle", type = ExprType.CSS),

				@ExtractBy(value = "//title/text()", type = ExprType.XPATH) }, op = OP.OR)

		public String title;



		@Inject

		@ExtractBy(value = "div.PubDate a[href~=http://my\\.oschina\\.net/]", type = ExprType.CSS)

		public String author;



		@Inject

		@ExtractBy(value = "发布于.\\s*(\\d+年\\d+月\\d+日)", type = ExprType.REGEX)

		public Date publishDate;



		@Inject

		@ComboExtract(value = {

				@ExtractBy(value = "div.PubDate", type = ExprType.CSS, setting = @Setting(outerHtml = true)),

				@ExtractBy(value = "(\\d+)评", type = ExprType.REGEX) }, op = OP.AND)

		public int commentNum;



		@Inject

		@ExtractBy(value = "span#p_favor_count", type = ExprType.CSS, setting = @Setting(function = @Function(value = "replace", args = {

				"+", "" })))

		public int collectNum;



		@Inject

		@ComboExtract(value = {

				@ExtractBy(value = "div[id=userComments]", type = ExprType.CSS, setting = @Setting(outerHtml = true)),

				@ExtractBy(value = "div.TextContent", type = ExprType.CSS) }, op = OP.AND, multi = true)

		public List commentContents;



		@Inject

		@ExtractBy(value = "div[id=toolbar_wrapper]", setting = @Setting(fliters = { "b", "span" }), type = ExprType.CSS, impl = Document.class)

		public String weibo;
