Reformatting mixed content XML in IntelliJ IDEA

Question

I want to prevent IDEA to insert line breaks around certain elements, analogous to HTML formatting where certain elements (like <b>) are kept inline.

I have an XML dialect with a DTD that declares mixed content.

DTD:

<!ELEMENT mixed (#PCDATA|inline)*>
<!ELEMENT inline #PCDATA>

XML file:

<mixed>
  Some text with <inline>inline elements</inline>
  and a line break.
</mixed>

When I reformat the XML file, IDEA transforms it to

<mixed>
  Some text with 
  <inline>inline elements</inline>
  and a line break.
</mixed>

I have looked at all the options on Code style->XML->Other. The "Keep whitespace" option is too restrictive, as I want IDEA to break long lines.

Answer 1

After trying many things, I'm getting the impression that this will not be possible. I've submitted a feature request:

Answer 2

In IDEA 13 you could use new Formatter Control feature to disable autoformat of selected lines of code. To enable this feature you should mark the following checkbox in the project settings:

Then insert selected markers in the comments to demarcate pieces of code that should not be formatted by Reformat Code tool, something like:

<root>
    <!-- @formatter:off -->
    <mixed>
        Some text with <inline>inline elements</inline>
        and a line break.
    </mixed>
    <!-- @formatter:on -->

    <mixed>
        Some text with
        <inline>inline elements</inline>
        and a line break.
    </mixed>
</root>

Unfortunately, there is no such feature in previous versions of IDEA and in that case the only known to me option is to format your code manually and not to use Reformat Code tool.
