我正在使用一個工具，而且我在最後一個步驟中，但是我遇到了一個小問題，將不勝感激，您可以給我一個提示。 我有這3個表格，我只能從第2個數據中獲取數據，我如何才能達到寫入的第三個數據升級保修和服務信息？從HTML中的第三個表格獲取數據
下面是表代碼：
<body>
\t \t <div id="ibm-pcon">
\t \t \t <div id="ibm-content">
\t \t \t \t <div id="ibm-leadspace-head" class="ibm-alternate">

\t \t \t \t \t \t <br></br>
\t \t \t \t \t \t <script type="text/javascript">currentDate();</script>
\t \t \t \t \t \t <br></br>
\t \t \t \t \t \t
\t \t \t \t \t \t \t <!--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>
\t \t \t \t \t \t \t <!--END OPTIONAL BREADCRUMBING-->
\t \t \t \t \t \t

try {
String getTextArea;
getTextArea = textArea.getText();
String[] arr = getTextArea.split("\\n");
String type = null;
String serial = null;
int line = 0;

textArea_1.append("Empty Line" + '\n');
continue;

Document doc = Jsoup.connect(html).get();
Elements tableElements = doc.select("table");
java.util.Iterator<Element> ite = tableElements.select("tr").iterator();

這是一個不錯的主意，但不幸的是它不工作，因爲我的HTML是不是因爲你是顯示的，我必須首先將數據添加到我的工具提出了文本，然後按運行，以便爲每個數據都會給我預期的結果，現在當我嘗試你的代碼時，它給了我大小爲表大小，然後沒有其他打印！ 我使用的網站是類似 http://w3-01.ibm.com/pc/entitle/pg2/Service.wss/mts/Lookup?type=12345&serial=123456789 –
我試圖改變文檔，它的工作原理現在：D Document doc = Jsoup.connect（html）.get（）; –
@AboelmagdSaad我使用的html正是您提供的。我假設你使用Jsoup.connect（）來獲取HTML源代碼。只要返回的HTML源代碼與您在問題中提到的代碼相似，我的代碼/ Jsoup就可以工作。要檢查您獲得的HTML源代碼，請調用Document.html（）。 –
