有没有办法在DOM中的HTML标签之间逐字提取文本?
问题描述:
例如,对于HTML文档:
For example, for an HTML document:
<html>
<body>
<p>Hello <b>world</b></p>
</body>
</html>
我知道我可以使用 getTextContent()
要获得Hello world
,但是有没有办法获取Hello< b> world< / b>
?
I know I can use getTextContent()
to get "Hello world"
, but is there a way to get "Hello <b>world</b>"
?

在Java中,您可以应用XSLT转换: https://docs.oracle.com/javase/tutorial/jaxp/xslt/writingDom.html

您需要的是检索元素子树的XML内容。解决这个问题的SO有几个问题:
