How load attribute "style" in the content?

Hi!

I have a problem, when load content in the CKEditor... I want save all style attribute by HTML-objects, when I load this objects.

For example:

before load in CKEditor:

<p style="some properties"> Hello </p>

after load in CKEditor:

<p> Hello </p>

How I can load content with save all style attributes?

Thanks!
