nekohtml经典小例子一个
public class Demo {public static String TextExtractor(Node root){ //若是文本节点的话，直接返回 if (root.getNodeType() == Node.TEXT_NODE) { return root.getNodeValue().trim(); } if(root.getNodeType() == Node.ELEMENT_NODE) { Element elmt = (Element) root; //抛弃脚本 if (elmt.getTagName().equals("STYLE") || elmt.getTagName().equals("SCRIPT")) return ""; NodeList children = elmt.getChildNodes(); StringBuilder text = new StringBuilder(); for (int i = 0; i < children.getLength(); i++) { text.append(TextExtractor(children.item(i))); } return text.toString(); } //对其它类型的节点，返回空值 return "";}public static void main(String[] args) throws Exception{ //生成html parser DOMParser parser = new DOMParser(); //设置网页的默认编码 parser.setProperty( "http://cyberneko.org/html/properties/default-encoding", "gb18030"); //input file BufferedReader in = new BufferedReader(new FileReader("input.htm")); parser.parse(new InputSource(in)); Document doc = parser.getDocument(); //获得body节点，以此为根，计算其文本内容 Node body = doc.getElementsByTagName("BODY").item(0); System.out.println(TextExtractor(body));}}
