this code is unable to read values of the dcr..plz help

Amrita1

Hi,
I am trying to read values from an array of dcrs. This seems to get the dcr names, but I am not getting the values.. Please suggest..

Thanks in advance..

my $directory="/default/main/2008_10_dev/WORKAREA/users/templatedata/ContentTypes/CATALOG/data";
print LOG "directory is $directory\n";
opendir(DIR, $directory) or die "could not open $directory: $!\n";
my @files = grep { $_ ne '.' && $_ ne '..' } readdir DIR;
my $iwhome = TeamSite::Config::iwgethome();
my $path = iwpt_get_dcr_name();
$path =~ s#\\#/#g;
$path =~ s#(.*/WORKAREA)/(\w+)(.*)#$1/$2#;
$path =~ s|/.iwmnt||;
foreach my $index ( @files ) {
my $xmlin = "/templatedata/ContentTypes/CATALOG/data/$index";
my $parser = TeamSite: Smiley Very Happy

CRparser->new();
my $fullpatha = $path.$xmlin;
if (!open (FH, "$fullpatha")){
print LOG "Error Opening $xmlin\n";
}
my $xml = do { local $/; };
my $rootnode = $parser->parse("$xml",'dcr');
print LOG "rootnode is $rootnode\n";
if ($rootnode) {

$Value1 = $rootnode->value('CONTENT_ID');
print LOG "catlog_value is $Value1\n";

}

}

Print out your path. I suspect it is not what you need it to be.

thanks a lot for the response..

I tried to hardcode the required /default path, still its not finding the dcr values..Is there anything with the parsing..?

My question is that is it really reading the XML Can you print out the XML when it reads the file or is it failing on the open ?

Amrita1

yes, this is reading the xml..
it returned the rootnode when i printed it:

rootnode is TeamSite:: DCRnode=ARRAY(0x5044d8)

does not this mean, it is reading the xml?

nipper

Yes then it is reading the XML Then the issue is with this statement,

$Value1 = $rootnode->value('CONTENT_ID');

Can you post the DCR ? It certainly not parsing it the way you think it is.

Amrita1

plz find in the attachment

nipper

and what is *that* supposed to be ?

nipper

You are not getting the correct fields. You are asking for CONTENT_ID off of root, but it is not, it is a sub of CATALOG

try $rootnode->value('CATALOG.CONTENT_ID');

I use XML style DCRs so I am not as familar with using Perl to get to the IWOV style DCR.

Amrita1

thank you very much..that was it..awesome!!!

thanks again.. Smiley Happy

hi, I am facing some weird issue in regards to getting values from DCR.

this is what I am doing now .. in the logs it prints me node value for sure.

code goes here
[html]
my $docnode = $parser->parse($sampleXMLstring,'document');
if ($docnode){
open(LOG,">C:/inDIRCALLOUT.txt");
$imagevaluejustitem = $docnode->value('txtImage');
$imagevaluefromImageContent = $docnode->value('cntImageContent.txtImage');
$imagevaluefromparent = $docnode->value('globaltile.cntImageContent.txtImage');
print LOG "DOCNODE is: $docnode\n";
print LOG "imAGE VALUE IS: $imagevaluejustitem\n";
print LOG "imAGE VALUE IS: $imagevaluefromparent\n";
print LOG "image value is : $imagevaluefromImageContent\n";
close(LOG);
}
[/html]

In log I get
[html]
DOCNODE is: TeamSite: Smiley Very Happy

CRnode=ARRAY(0x1527cd4)
imAGE VALUE IS:
imAGE VALUE IS:
imAGE VALUE IS:
[/html]

Weird thing is if I run the same code from command line it gives me the dcr node information in the logs when I do just the child node request

[html]
my $docnode = $parser->parse($sampleXMLstring,'document');
if ($docnode){
open(LOG,">C:/inDIRCALLOUT_commndline.txt");
$imagevaluejustitem = $docnode->value('txtImage');
print LOG "$imagevaluejustitem\n";
close(LOG);
[/html]

Is it that I am missing something. All my dcrs are xml

nipper

1st things 1st, print $sampleXMLstring to a log in both examples and see that the data is identical.

Andy, your suggestion was helpful.
I have to loop through a list of dcrs and have to get the value of the node in each dcr. Previously(before posting my query) while logging I wasnt appending the log. Now I can see the value in the log. I should work now on how should I capture value of the node from each dcr into a variable before it fetches another dcr.

Thanks again.
