As sayed in title.

The example as below (it is hard to be with repeat ... repeat while) :

skinparam conditionStyle InsideDiamond

:foo as starting label;      //same name 1
:read data;                       //same name 2
:generate diagrams;
if (more data?) then (yes)
  :This is backward1;
  :foo as starting label;    //sanme name 1
else (no)
  if (condition two?) then (no)
    :This is backward2;
    :read data;                  //same name 2
  else (yes)

Actually the only problem with your code is your "comments".  The comment symbol in Plantuml is ' not //.

However, that said, you can't append such comments to code lines like you have tried to do - which surprised me.  But you can use the enclosed comment format:  /' comment '/ at the end of lines.

So, delete all your comments and it works fine - it doesn't care about repeated text.  Put any comments on a line of their own prefixed with ' or embedded in /' and '/.

You are right, my comments cannot be like that.

But I means that I want that the first "foo as starting label" & the second "foo as starting label" can be merged as the first one and at the first place; The first "read data" & the second "read data" should be merge as the first one and at the first place.

OK, sorry, I misunderstood.  I'm afraid Plantuml is not very good at backwards paths on activity diagrams.  I tried 'label & goto' but the result is so poor it is not worth sharing.

The best I can offer is:

Emm, this diagram still can not reach my aim.

Another way, can we add "diamond" shape in  component diagram, then I can using it to draw conditions ? If do this,  I can just draw this activity diagram.

Hexagon is the closest shape Plantuml has to a diamond.  You could put in a Wanted Feature for a diamond shape; given they recently added hexagon I can't imagine adding a diamond would be too difficult.
