使用JSOUP解析HTML文档，无法选择表节点？
[英]Parsing HTML Document with JSOUP, can't select table node?
问题描述
I've already looked into several Stack Overflow topics with similar questions. 
我已经查看了几个类似问题的Stack Overflow主题。
I have the following problem: I have a simple html page, downloaded and saved locally as .html File, I am parsing it with JSoup to read the content of that table. 我有以下问题：我有一个简单的html页面，下载并在本地保存为.html文件，我用JSoup解析它以读取该表的内容。 Unfortunately when I look for my table with .select("table") it returns me no Elements. 不幸的是，当我用.select（“table”）查找我的表时，它没有返回任何元素。 Hence I have debugged it, what I could notice is... my body node has one childnode, which appears to be solely String, and thus I assume I can't find any table node? 因此我调试了它，我能注意到的是......我的身体节点有一个子节点，它看起来只是字符串，因此我假设我找不到任何表节点？
Can anyone help me out please? 有人可以帮帮我吗？
Here is my code snippet: 这是我的代码片段：
for (Element table : doc.select("table.creditsuisse")) {
for (Element row : table.select("tr")) {
for (Element tds : row.select("td")){
for(Element link : row.select("href")){
System.out.println(link.text());
}
System.out.println(tds.text());
}
}
}
And here is how my input File looks like: 这是我的输入文件的样子：
<html>
<head>
</head>
<body>
<table class="creditsuisse" width="100%" cellspacing="0" cellpadding="0">

In order to read a local file in JSoup you would need to use the parse method that takes a File object rather than the one that takes HTML content. 为了读取JSoup的本地文件，您需要使用带有File对象的parse方法而不是带有 HTML内容的对象。 Replace 更换
Document doc = Jsoup.parse("C:\\...\\myFile.html", "UTF-8");
with 同
Document doc = Jsoup.parse(new File("C:\\...\\myFile.html"), "UTF-8");

How are you reading your document? 你是如何阅读你的文件的？ If it is just a string, then you need to convert it to the "Document" first You can try something like this: 如果它只是一个字符串，那么你需要先将它转换为“文档”你可以尝试这样的事情：
Document document = Jsoup.parse(YOUR_STRING);
Elements elements = document.getElementsByTag("table");
Element table = elements[0];
