hi,
you should be able to reference it like this:

(DHTMLEdit1.DOM.all.item('id1', 0) as IHTMLElement).setAttribute('background', 'D:\spawntest.jpg', 0);

where cell has a id of id1
<td id=id1>
and after tag should end up like:
<td id=id1 background=D:\spawntest.jpg>

If I select object (cell, page, etc...) in DHTMLEdit, I want to recognite selection in text.

Selected part of page is :
<td id=id1 background=D:\spawntest.jpg>

hi,
just ignore ReplaceInfo(St);
it is someones private function and unless they tell you it you never know.
i dont know what they were trying to do but it looks like all you need to do to replace the text is to :
do it like:
 

var
HTMLDoc : IHTMLDocument2;
Selection : IHTMLSelectionObject;
TextRange : IHTMLTxtRange;
St : String;
begin
HTMLDoc := DHTMLEdit1.DOM as IHTMLDocument2;
Selection := HTMLDoc.Selection as IHTMLSelectionObject;
if Selection.type_ = 'Text' then
begin
TextRange := Selection.CreateRange as IHTMLTxtRange;
St := DHTMLEdit1.FilterSourceCode(TextRange.htmlText);
St := 'hello';
TextRange.pasteHTML(St);
end;
end;

if you want to know what the text is thats is being replaced st contains it here:

<snip>
St := DHTMLEdit1.FilterSourceCode(TextRange.htmlText);
showmessage(st); //current selected text
St := 'hello'; //now change it
