Is it possible - yes, is it reasonable to do so - unclear?

The PT can call arbitrary programs and/or Perl code to do all sorts of things, one of which could be to go and modify the contents of a DCR - but I think you'd have to provide a good use-case scenario fo why you'd need to do this before implementing it because there are a number of factors that make this less than a "safe" or trivial thing to do.

HI,
It's very simple use-case.

Contributor fills a DCR Template and generates a relative html page and submit his work for approval.
After approval workflow engine starts Opendeploy and DataDeploy process.
I must deploy in a database table some values of a DCR Fieds and the URL of HTML Page tha it was generate.
So I tried to parse a DCR after generation process and modify a value of a node URLProducts.
I put this code in TPL

sub WriteUrlNode{

my $OutputPath = shift;
my $DcrPath = shift;
my (@line,$PathPage,$strToCompare,$IndexValue);
my $line;

$line=1;
$strToCompare="<item name=\"urlprodotto\">";
$PathPage = &decodePath($OutputPath,$WorkArea);
$FileName ="$DcrPath"."_prova";

open (INPUTDCR,"$DcrPath");
while(<INPUTDCR>){
push @line,$_;
}
close (INPUTDCR);

open(OUTPUTDCR,">$DcrPath");
for($i;$i<scalar(@line);$i++){
if(index($line[$i],$strToCompare)>0){
$line[$i+1] =~ s/^(.*)/<value>$PathPage<\/value>/g;
}
print OUTPUTDCR $line[$i];
}
close(OUTPUTDCR);

Are you saying that you want to change the contents of the DCR to include a field that provides the path / URL of the page that was generated from that DCR??

What happens if you generate more than one page from a single DCR?

Why not use TeamSite Extended Attributes to store the name of the generated page ? That way you wouldn't have to parse through the DCR nor attempt to change it's contents - you could use iwextattr to retrieve any previous value and/or to set or append any new value.

DataDeploy works with extended attributes as well as DCR content.

I guess I'm still failing to see why you need to programatically alter the contents of the DCR after the contributor has finished entering the data.

Thanks Fish!

First of all, where I can find documentation about iwextattr and his integration with datadeploy?

Adam Stoller

For information about iwextattr - try iwextattr -h or look in the TeamSite Command Line Tools manual.

For information about DataDeploy - read the Data Deploy manuals.
