JAVA解析HTML，获取待定元素属性

Document doc = Jsoup.parseBodyFragment(previewHtml); //html内容解析为Document
int index = 0;
StringBuffer stringBuffer = new StringBuffer();
Elements inputArray = doc.getElementsByTag(“input”);//对应的元素数组
for(int a=0;a<inputArray.size(); a++) {
Element element = inputArray.get(a);
String type = element.attr(“type”); //获取元素属性的值
String field = element.attr(“name”);
if(“text”.equals(type) && index<3) {
String title = element.attr(“title”);
stringBuffer.append(“{field:'”+field+”‘,title:'”+title+”‘,width:100,align:’center’},”);
index++;
} else break;
}
System.out.println(stringBuffer);
