Maintain format of XML comment section on auto-formatting in Eclipse

Question

In Eclipse (Helios) I have this XML source file:

<?xml version="1.0" encoding="utf-8"?>
<!--
I wanted to 
===========
save this format of the comments.

-->
<x>
</x>

On formatting the file (Ctrl+Shift+F) I got the comment reformatted.

<?xml version="1.0" encoding="utf-8"?>
<!-- I wanted to =========== save this format of the comments. -->
<x>
</x>

Is there an option to switch off pretty-printing comment sections?

Answer 1

I'm using Eclipse 3.6.0.

In Windows > Preferences > XML > XML Files > Editor:

Uncheck the Join lines option.

Answer 2

您只能选择部分XML文件进行格式化，并省略注释部分。
