xml:check-format produces false-positives in some mixed-content scenarios

Open sewe opened this issue 4 years ago • 3 comments

When checking (X)HTML documents for correct indentation, I run into some strange false-positives.

The following minimal (X)HTML document is the result of some systematic exploration on my part. It should explain where I see the false-positives, namely in certain cases of mixed content (as is used when HTML inline elements like <em> are involved):

<html>
  <head>
    <title>Example</title>
  </head>
  <body>
    <p>This validates.</p>
    <p>This does, <em>too.</em></p>
    <p>Paragraphs with multiple lines also validate:
      Like this.</p>
    <p>They even validate when inline elements are involved.
      Like <em>here.</em>
      Nice, isn't it?</p>
    <p>But we hit a bug if the inline elements covers the whole line.
      <em>Like here.</em></p>
    <p>Or if more text follows the inline element:
      <em>Like in the next line.</em>
      See?</p>
    <p>But placing the closing paragraph tag on a different line is (whitespace-wise) different:
      <em>This "workaround" will bite you when using p::after in CSS.</em>
    </p>
  </body>
</html>
