[英]jsoup tag extraction problem
Elements size = doc.select("div:contains(test:)");
how can i extract the value example and example1 from this html tag....using jsoup.. 我如何从这个html标记中提取值example和example1。...使用jsoup ..
Since this HTML is not semantic enough for the final purpose you have (a <br>
cannot have children and :
is not HTML), you can't do much with a HTML parser like Jsoup. 由于此HTML的语义不足以实现您的最终目的(
<br>
不能有子对象,而:
不是HTML),因此您无法使用Jsoup之类的HTML解析器做很多事情。 A HTML parser isn't intented to do the job of specific text extraction/tokenizing. HTML解析器无意执行特定的文本提取/标记化工作。
Best what you can do is to get the HTML content of the <div>
using Jsoup and then extract that further using the usual java.lang.String
or maybe java.util.Scanner
methods. 最好的办法是使用Jsoup获取
<div>
的HTML内容,然后使用常规的java.lang.String
或java.util.Scanner
方法进一步提取该内容。
Here's a kickoff example: 这是一个启动示例:
String html = "<div style=\"height:240px;\"><br>test: example<br>test1:example1</div>";
Document document = Jsoup.parse(html);
Element div = document.select("div[style=height:240px;]").first();
String[] parts = div.html().split("<br />"); // Jsoup transforms <br> to <br />.
for (String part : parts) {
int colon = part.indexOf(':');
if (colon > -1) {
System.out.println(part.substring(colon + 1).trim());
}
}
This results in 这导致
example example1
If I was the HTML author, I would have used a definition list for this. 如果我是HTML作者,那么我将为此使用定义列表 。 Eg
例如
<dl id="mydl">
<dt>test:</dt><dd>example</dd>
<dt>test1:</dt><dd>example1</dd>
</dl>
This is more semantic and thus more easy parseable: 这更具语义,因此更易于解析:
String html = "<dl id=\"mydl\"><dt>test:</dt><dd>example</dd><dt>test1:</dt><dd>example1</dd></dl>";
Document document = Jsoup.parse(html);
Elements dts = document.select("#mydl dd");
for (Element dt : dts) {
System.out.println(dt.text());
}
