PT: Differentiat between "Preview" & "Generate"

I'm trying to write a PT that shows the content in different ways depending on if you have pressed the "Generate" or the "Preview"-Button.

I'm thinking of something like:

<iw_if expr=' {iw_value name="$which_value"/} eq "what" ' >
<iw_then>
whole page red
</iw_then>
<iw_else>
whole page green
</iw_else>
</iw_if>

What value should I replace "$which_value" with. The "$which_value" should be something like preview true/false.

Any suggestions, sample code, advice would be greatly appreciated!

Ah - I was looking for this yesterday for a different thread...
[note: space inserted after '<' to get it to show up reasonably here]

< iw_perl>
    my $outputName = iwpt_get_ofile_name();
    my $dcrName = iwpt_get_dcr_name();
    my $param = iwpt_get_flag_param('-oprefix');
    if($param eq ''){
        #Its a Generate
    }
    else{
    #A preview
   }
< /iw_perl>

I am trying to alter the first line of my generated page into a html or a xml tag, depending on if it is being previewed or generated. Based on ghoti's suggestion, here are the first few lines of my PT. The switch is not happening -- In case of both previewing and generating the < html> or < xml> tags dont show up. Is there something else I should be doing?? Any ideas?? I am using TS 5.01 on Solaris. Thanks in advance.

< ?xml version="1.0" encoding="UTF-8"?>
< iw_pt name="Press_Release">
< iw_perl>
< ![CDATA[
my $outputName = iwpt_get_ofile_name();
my $dcrName = iwpt_get_dcr_name();
my $param = iwpt_get_flag_param('-oprefix');
if($param eq '')
{
< html>
} else {
< xml>
}
]] >
< /iw_perl>
< ![CDATA[
.......Rest of PT.........

yes.
The problem is that you're inside a <iw_perl> tag, so to output something you need to : iwpt_output
In your example:
...
my $param = iwpt_get_flag_param('-oprefix');
if($param eq '')
{
iwpt_output("< html>\n");
} else {
iwpt_output("< xml>\n ");
}
