I know that this is Usenet, not the Web. I thought that code is too big 
and instead of posting code here it would be better to prepare a working 
example.

Here's the code:

var is_block_style = function (el) {
     var el_style;
     if (window.getComputedStyle) {
         el_style = window.getComputedStyle(el, 
null).getPropertyValue('display');
     } else {
         el_style = el.currentStyle.display;
     }
     return el_style;
};

var imgClassName = 'testimg';

var tidyHTML = function (node) {
     var elms = node.childNodes,
         i = elms.length,
         text = '',
         elm;

     if (!node.hasChildNodes() && (node.nodeName.toLowerCase() === 'img' 
&& !(new RegExp('(^|\\s)' + imgClassName + 
'(\\s|$)')).test(node.className))) {
         node.parentNode.removeChild(node);
         return text;
     }

     while (i--) {
         elm = elms[i];

         if (elm.nodeType === 1) {
             text += tidyHTML(elm);
         } else if (elm.nodeType === 3) {
             text += elm.data;
         } else if (elm.nodeType !== 3 && elm.nodeType !== 1) {
             elm.parentNode.removeChild(elm);
         }
     }

     if (typeof text !== 'undefined') {
         if (is_block_style(node) === 'block') {
             node.parentNode.insertBefore(document.createElement('br'), 
node.nextSibling);
         }
         //node.parentNode.replaceChild(document.createTextNode(text), 
node);
     }
     return text;
};
