我正在研究一种工具而且我已经完成了最后一步，但是我遇到了一个小问题，请您能给我一个提示。 我有这3个表，我只能从前2个获得数据，如何才能到达第三个表格，升级保修和服务信息？
这是表格代码：
<body>
<div id="ibm-pcon">
<div id="ibm-content">
<div id="ibm-leadspace-head" class="ibm-alternate">
<div id="ibm-leadspace-body">
<br></br>
<script type="text/javascript">currentDate();</script>
<br></br>
<!--BEGIN OPTIONAL BREADCRUMBING--> <span style="font-size: small;"><a href="/pc/entitle/pg2/Service.wss/display/MachineHome">Machine Lookup</a> > <a href="/pc/entitle/pg2/Service.wss/mts/Lookup">Warranty Information</a> > </span>
<!--END OPTIONAL BREADCRUMBING-->
<br></br>
<h1>PEW | Warranty Information</h1>
</div>
</div>
<!-- CONTENT_BODY -->
<div id="ibm-content-body">

我的工作代码是：

try {
String getTextArea;
getTextArea = textArea.getText();
String[] arr = getTextArea.split("\\n");
String type = null;
String serial = null;
int line = 0;
for(String s : arr) {
line++;
if(s.isEmpty()) {
textArea_1.append("Empty Line" + '\n');
continue;
}
type = s.substring(0, 4);
serial = s.substring(5, 12);
String html = "bla bla bla + type + serial;
Document doc = Jsoup.connect(html).get();
Elements tableElements = doc.select("table");
java.util.Iterator<Element> ite = tableElements.select("tr").iterator();
Elements tableElement = doc.select("tr");
java.util.Iterator<Element> ite1 = tableElement.select("table").iterator();
ite.next();
ite1.next();
String result,result1,result2;
result = ite.next().text();
result1 = ite1.next().text();
Scanner sr = new Scanner(result);
Scanner sr1 = new Scanner(result1);
// System.out.println(result);
// System.out.println(result1);
// result of first table
while(sr.hasNext()) {
result = result;
ite.next().text();
String lineOfType;
lineOfType = ite.next().text();

String model;
model = lineOfType.substring(18, 21);

textArea_1.append(line + "-" + type + '\t' + model + '\t' + serial + " " + country + " ");

// getting the elements for the 3rd table, but not working as expected, it gets the secnd table data.

让＆＃39;说改变另一种更容易获得这些表的方法。我建议使用org.jsoup.nodes.Element.select()逐个获取表格。
结帐link了解如何使用jsoup-selector-syntax获取元素。
