Hi all,

When upgrading from 1.15.1 to 1.15.2 I appear to have encountered unexpected insertion of spaces - is this a bug or desired behaviour?

In this test with a multiline string:

<h1>This is my comment</h1>

<p>Lorem ipsum</p>

<span>Thanks</span>

1.15.1 output of val parsed = Jsoup.parse(textWithHtml):

<h1>This is my comment</h1>
<p>Lorem ipsum</p><span>Thanks</span>

1.15.2 output of val parsed = Jsoup.parse(textWithHtml):

<h1>This is my comment</h1>
<p>Lorem ipsum</p> <span>Thanks</span>

(space inserted between </p> and <span>)

EDITED: To remove references to using .text() on the output of Jsoup.parse

Thanks for sharing the examples. I'm trying to reproduce this using Jsoup 1.15.2 and Java 17.0.4 since I don't have Kotlin installed on my machine and the following code snippet produces a space between ipsum</p> <span> as well when I use the Jsoup.parse() method without the text() method.

Document jsoupHtml() throws IOException {
    String multiLineHtml = """
        <h1>This is my comment</h1>

        <p>Lorem ipsum</p>

        <span>Thanks</span> """;
    Document resultingHtml = Jsoup.parse(multiLineHtml);

    return resultingHtml;
    }

//The above code produces this Html for me:

<html>
 <head></head>
 <body>
  <h1>This is my comment</h1>
  <p>Lorem ipsum</p> <span>Thanks</span>
 </body>
</html>

When I try using the text() method like you do in your example, I don't see an extra space in the final String result.

String jsoupHtml() throws IOException {
    String multiLineHtml = """
        <h1>This is my comment</h1>

        <p>Lorem ipsum</p>

        <span>Thanks</span> """;
    Document resultingHtml = Jsoup.parse(multiLineHtml);
    String textOfHtml = resultingHtml.text();
    
    return textOfHtml;
    }

The above code snippet produces the following String for me without extra spaces when using text() and System.out.println() to print the result to a Ubuntu Linux terminal:

This is my comment Lorem ipsum Thanks

Thanks for sharing your example but maybe I'm missing something when trying to reproduce this issue?

Thanks so much for your time both, I've edited my post to remove references to using .text() - it didn't line up with the HTML outputs I pasted... I'm not sure what I was smoking there.

I've created a tiny scala repro case located here, also attached as two jars in a zip (each one with a different jsoup version)

I'm Ubuntu / Java 11

I know it looks like it, but jsoup is not inserting a space here. It is actually collapsing a newline into a single space - and would collapse multiples of those if present.

I have improved the pretty-printer to now also collapse this space, similar to the earlier behavior.

Thanks for the report!
