如何解析HTML并获得CSS样式 [英] How to parse HTML and get CSS styles
问题描述
我需要解析HTML并找到相应的CSS样式。我可以分别解析HTML和CSS，但我无法将它们组合起来。例如，我有一个像这样的XHTML页面：
I need to parse HTML and find corresponding CSS styles. I can parse HTML and CSS separataly, but I can't combine them. For example, I have an XHTML page like this:
<html>
<head>
<title></title>
</head>
<body>
<div class="abc">Hello World</div>
</body>
</html>
我必须搜索hello world并找到它的类名，之后我需要从外部CSS文件中找到它的样式。使用Java，JavaScript和PHP的答案都可以。
I have to search for "hello world" and find its class name, and after that I need to find its style from an external CSS file. Answers using Java, JavaScript, and PHP are all okay.
推荐答案
使用 jsoup 库，它是一个HTML Parser。你可以看看例如这里
例如你可以做类似的事情这个：
Use jsoup library in java which is a HTML Parser. You can see for example here
For example you can do something like this:
String html="<<your html content>>";
Document doc = Jsoup.parse(html);
Element ele=doc.getElementsContainingOwnText("Hello World").first.clone(); //get tag containing Hello world
HashSet<String>class=ele.classNames(); //gives you the classnames of element containing Hello world
您可以进一步探索库以满足您的需求。
You can explore the library further to fit your needs.
