在 Java 中使用同级标签解析 HTML 内容(或)在两个之间查找内容标签
背景:我正在编写一个 Java 程序来遍历 HTML 文件,并将标签中除 或
之外的所有内容替换为 Lorem Ipsum 。我最初是用正则表达式来做到这一点的,只是删除了 > 之间的所有内容。和 a <,实际上效果很好(我知道这是亵渎的),但我试图将其变成其他人可能会觉得有用的工具,所以我不敢再通过尝试使用正则表达式来威胁宇宙的神圣性在 HTML 上。
我正在尝试使用 HtmlCleaner,这是一个吸引我的 Java 库,因为它没有其他依赖项。但是,尝试实现它时我无法像这样处理 html:
<div>
This text is in the div <span>but this is also in a span.</span>
</div>
问题很简单。当 TagNodeVisitor 到达 div 时,如果我用适量的 Lipsum 替换其内容,它将消除 span 标签。但如果我只深入到没有其他子节点的 TagNode,我就会错过第一段文本。
HtmlCleaner 有一个 ContentNode 对象,但该对象没有替换方法。我能想到的解决这个问题的任何方法似乎都太复杂了。有谁熟悉使用 HtmlCleaner 或您更熟悉的其他解析库来处理此问题的方法吗?
Background: I'm writing a Java program to go through HTML files and replace all the content in tags that are not <script>
or <style>
with Lorem Ipsum. I originally did this with a regex just removing everything between a > and a <, which actually worked quite well (blasphemous I know), but I'm trying to turn this into a tool others may find useful so I wouldn't dare threaten the sanctity of the universe any more by trying to use regex on html.
I'm trying to use HtmlCleaner, a Java library that attracted me because it has no other dependencies. However, trying to implement it I've been unable to deal with html like this:
<div>
This text is in the div <span>but this is also in a span.</span>
</div>
The problem is simple. When the TagNodeVisitor reaches the div, if I replace its contents with the right amount of lipsum, it will eliminate the span tag. But if I drill down to only TagNodes with no other children, I would miss the first bit of text.
HtmlCleaner has a ContentNode object, but that object has no replace method. Anything I can think of to deal with this seems like it must be far too complicated. Is anyone familiar with a way to deal with this, with HtmlCleaner or some other parsing library you're more familiar with?

您几乎可以使用 JSoup setters 做任何您想做的事情,
这适合您吗?
You can pretty much do anything you want with JSoup setters
Would that suit you ?
HtmlCleaner 的 ContentNode 有一个方法 getContent() ,返回 java.lang.StringBuilder。这是可变的,可以更改为您想要的任何值。
HtmlCleaner's ContentNode has a method getContent() that returns a java.lang.StringBuilder. This is mutable and can be changed to whatever value you want.
