我的目标是读取<tr><td>something<td/><td>something<td/><td>something<td/></tr>
这个是我自己写的
public void readHtml() {
Map<String,Object> htmls = new HashMap<String,Object>();
SAXBuilder sb = new SAXBuilder();
try {
Document doc = sb.build(this.getClass().getClassLoader().getResourceAsStream("TYPE.html"));
Element root = doc.getRootElement();
List list = root.getChildren("tr");
for(int i = 0;i<list.size();i++){
Element element=(Element)list.get(i);
String name = element.getChildText("td");
System.out.println(name);
}
} catch (JDOMException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
HtmlDaoImpl hdm = new HtmlDaoImpl();
hdm.readHtml();
}
}请问我改怎么用jdom获取tr下面三个td节点的内容呢.我总是只获取第一个获取不到2和第三个我很少用到jdom所以基本不懂...看我熬夜辛苦帮忙下吧各位写个demo看看....

使用jsoup更方便。http://jsoup.org/
http://jsoup.org/cookbook/extracting-data/selector-syntax
URL url =
Elements tds = Jsoup.parse(url,1000).select("td");
for(Element td : tds){ String text = td.text();}

首先说明LZ贴出来的td结束标签是错的。。。<td/>改为</td>，不然读取根节点就报错。。。改为：即可 public static void readXML3() { // Map<String, Object> htmls = new HashMap<String, Object>(); SAXBuilder sb = new SAXBuilder(); try { Document doc = sb.build(new FileInputStream("f:/test.xml")); // 改为LZ自己的读路径方式 Element root = doc.getRootElement(); List list = root.getChildren("tr"); // 取tr元素 for (int i = 0; i < list.size(); i++) { Element element = (Element) list.get(i); List list_td = element.getChildren(); // 取td元素 for (int k = 0; k < list_td.size(); k++) { Element element_td = (Element) list_td.get(k); String name = element_td.getText(); // 取td文本值 System.out.println(name); } } } catch (JDOMException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } }

与上面一样。。只是调整格式 方便看： public static void readXML3() { // Map<String, Object> htmls = new HashMap<String, Object>(); SAXBuilder sb = new SAXBuilder(); try { Document doc = sb.build(new FileInputStream("f:/test.xml")); // 改为LZ自己的读路径方式 Element root = doc.getRootElement(); List list = root.getChildren("tr"); // 取tr元素 for (int i = 0; i < list.size(); i++) { Element element = (Element) list.get(i); List list_td = element.getChildren(); // 取td元素 for (int k = 0; k < list_td.size(); k++) { Element element_td = (Element) list_td.get(k); String name = element_td.getText(); // 取td文本值 System.out.println(name); } } } catch (JDOMException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } }
