Jsoup删除字符串中的多个空格

Question

I am trying to use jsoup.clean with

    Whitelist.relaxed().preserveRelativeLinks(true);
    Jsoup.clean(html, wl);

My html is a string message = "This is a simple string messages with double spaces"

There are double spaces in the string. But when I do .clean() , it trims the spaces. I want to preserve these spaces. How do I do it? Event .basic() and .simpleText() does not work.

Answer 1

There is an overload for clean that takes in a Document.outputSettings object:

public static String clean​(String bodyHtml, String baseUri, Safelist safelist, Document.OutputSettings outputSettings)

Using that, you can set prettyPrint to false:

public boolean prettyPrint()

Get if pretty printing is enabled. Default is true. If disabled, the HTML output methods will not re-format the output, and the output will generally look like the input.

So you end up with something like this:

Whitelist.relaxed().preserveRelativeLinks(true);
Jsoup.clean(html, "", wl, new Document.OutputSettings().prettyPrint(false));

That should get you what you're looking for.
