java - 使用 JSoup 返回来自特定 div 的链接中的所有文本

Question

我正在使用 JSoup 来解析特定 div 中的链接列表。我可以使用 #div>a cssQuery 语法很好地获取链接。但是我无法从里面获取文本:

private static Elements getLinkList(String URL) throws IOException {
 /* Download HTML page */
 URL website = new URL(URL);
 ReadableByteChannel readableByteChannel = Channels.newChannel(website.openStream());
 FileOutputStream fileOutputStream = new FileOutputStream(HTML_DOC);
 fileOutputStream.getChannel().transferFrom(readableByteChannel, 0, Long.MAX_VALUE);

 /* Collect list of links */
 File input = new File(HTML_DOC);
 Document document = Jsoup.parse(input, "UTF-8", URL);

 return document.select("#div>a");
}

我试图从标签中获取文本，但它是空白的。

<div id="div">
    <a href="http://www.sample.com/doc.doc" target="_blank">Installation guideline - Citrix XenApp 7.6 for PAS-X.doc<br></a>
</div>

Answer 1

答案不需要对我在 OP 中发布的代码进行代码更改:

private static Elements getLinkList(String URL) throws IOException {
 /* Download HTML page */
 URL website = new URL(URL);
 ReadableByteChannel readableByteChannel = Channels.newChannel(website.openStream());
 FileOutputStream fileOutputStream = new FileOutputStream(HTML_DOC);
 fileOutputStream.getChannel().transferFrom(readableByteChannel, 0, Long.MAX_VALUE);

 /* Collect list of links */
 File input = new File(HTML_DOC);
 Document document = Jsoup.parse(input, "UTF-8", URL);

 return document.select("#div>a");
}

但是在处理数据时，从链接 Element 本身检索文本，即 String titleText = link.text()，并完成:

Elements links = getLinkList(URL); // Retrieve list of Elements from above method

for (Element link: links) {
 String linkText = link.toString();
 String titleText = link.text();
 String formattedLink = org.apache.commons.lang3.StringUtils.substringBetween(linkText, "<a href=\"", "\"");

 System.out.println(titleText);
 System.out.println(formattedLink);
}
