How to force exist to retrieve an HTML file "as is", not adding <?xml and not merging </-s? -

does know how force exist retrieve html file "as is", not adding <?xml , not merging </-s?

even wikipedia wikipedia says:

• include space in empty-element tags: example <br /> instead of <br/>.
• include explicit close tags elements permit content left empty (for example, <div></div>, not <div />).

case:

html file stored in exist db:

<div id="idadadscreen">   <div id="idadadtop"></div>   <div id="idadadmiddle">     <div id="idadadleft"></div>     <div id="idadadcenter"></div>     <div id="idadadright"></div>   </div>   <div id="idadadbottom"></div> </div> 

when retrieved wget, empty tags melt:

<?xml... ?>  <div id="idadadscreen">     <div id="idadadtop"/>     <div id="idadadmiddle">        <div id="idadadleft"/>         <div id="idadadcenter"/>         <div id="idadadright"/>      </div>      <div id="idadadbottom"/> </div> 

in chrome , others, object hierarchy laughs on />

<div id="idadadscreen">     <div id="idadadtop">         <div id="idadadmiddle">             <div id="idadadleft">                 <div id="idadadcenter">                     <div id="idadadright"></div>                     <div id="idadadbottom"></div>                 </div>             </div>
