解析html中的table内容

最近接受了一个需求 需要解析网页源码来实现，所以写了一个解析网页中table的方法，给大家分享一下

这里面用到了htmlparser，下载地址：http://htmlparser.sourceforge.net/

 

URL url = new URL("http://");
		HttpURLConnection connection = (HttpURLConnection) url
				.openConnection();
		Parser parser = new Parser();
		parser.setConnection(connection);
		parser.setEncoding(parser.getEncoding());
		NodeFilter filter_tab = new TagNameFilter("table");
		NodeList nodelist = parser.parse(filter_tab);
		HashMap map = null;
		ArrayList list = new ArrayList();
		if (nodelist != null && nodelist.size() > 0) {
			for (int i = 0; i < nodelist.size(); i++) {
				TableTag table = (TableTag) nodelist.elementAt(i);
				TableRow[] rows = table.getRows();

				if (rows != null && rows.length > 0) {
					for (int j = 0; j < rows.length; j++) {
						map = new HashMap();
						TableColumn[] cols = rows[j].getColumns();
						
						for (int k = 0; k < cols.length; k++) {
							System.out.println(cols[k].toHtml().trim());
							map.put(k, cols[k].toPlainTextString().trim());
						}
						
					}
				}
			}
		}
