asked on

Get <p>, <span>, <ul> and <ol> from DHTMLEdit

How can I get the code from a paragraph or span tag in DHTMLEdit?
What I want to do is change a paragraph tag from <p> to somethig like <p style=""> etc... I want to do the same thing with the span, ol and ul tags, but I have no idea how to do this.

This is not what I ment, I know how to get and replace all of them, but i need the tag from the current line the caret is in.
mmm...you said --> What I want to do is change a paragraph tag from <p> to somethig like <p style="">....

So please explain better what do you need (maybe with some example)

Well I'm trying to make a format paragraph dialog, like in Front Page. It has the align property, then there's indenting and spacing.
This is where I got so far:

procedure TForm1.Button1Click(Sender: TObject);
var
 r: IHTMLTxtRange;
begin
r := DHTMLEdit1.DOM.selection.createRange as IHTMLTxtRange;
FormatParagraphWin.ShowModal;
if FormatParagraphWin.ModalResult = mrOK then
 begin
  if FormatParagraphWin.AlignBox.ItemIndex = 0 then
   r.parentElement.style.textAlign := ''
  else
   r.parentElement.style.textAlign := FormatParagraphWin.AlignBox.Items.Strings[FormatParagraphWin.AlignBox.ItemIndex];
   r.parentElement.style.lineHeight := OleVariant(IntToStr(FormatParagraphWin.SpBox.ItemIndex * 50) + '%');
   r.parentElement.style. <-- here I wanna add the indent and spacing property, but I don't know how. I want to add these : indent before, indent after, indent first line, spacing before, spacing after and word spacing.

Thanks for your help, but I've just solved the problem myself, like this:


procedure TForm1.Button1Click(Sender: TObject);
var
 r: IHTMLTxtRange;
begin
if DHTMLEdit1.DOM.selection.type_ = 'Text' then
 begin
  r := DHTMLEdit1.DOM.selection.createRange as IHTMLTxtRange;
  FormatParagraphWin.ShowModal;
   // set paragraph styles
  if FormatParagraphWin.ModalResult = mrOK then
   begin
    if FormatParagraphWin.AlignBox.ItemIndex = 0 then
     r.parentElement.style.textAlign := ''
    else
     r.parentElement.style.textAlign := FormatParagraphWin.AlignBox.Items.Strings[FormatParagraphWin.AlignBox.ItemIndex];
    r.parentElement.style.marginLeft := OleVariant(FormatParagraphWin.IndBefore.Value);
    r.parentElement.style.marginRight := OleVariant(FormatParagraphWin.IndAfter.Value);
    r.parentElement.style.textIndent := OleVariant(FormatParagraphWin.IndFirst.Value);
    r.parentElement.style.marginTop := OleVariant(FormatParagraphWin.SpBefore.Value);
    r.parentElement.style.marginBottom := OleVariant(FormatParagraphWin.SpAfter.Value);
    r.parentElement.style.wordSpacing := OleVariant(FormatParagraphWin.SpWord.Value);
    r.parentElement.style.lineHeight := OleVariant(IntToStr((FormatParagraphWin.SpBox.ItemIndex + 1)*50) + '%');
    // reset dialog controls
    with FormatParagraphWin do
     begin
      IndBefore.Value := 0;
      IndAfter.Value := 0;
      IndFirst.Value := 0;
      AlignBox.ItemIndex := 0;
      SpBefore.Value := 0;
      SpAfter.Value := 0;
      SpWord.Value := 0;
      SpBox.ItemIndex := 1;
     end;
   end;
 end;
end;
Solved by yourself?
I hope that it is, because it seems just that you got exactly the needed params after my link post....

BTW good work.

Cheers!
