in thread Copy portion of XML elements from one XML file to another exiting XML file

Hi Corion - Sorry for confusing you, Here is my complete function GetMappletList() i am trying to call,but i am calling it from same script in which the function was declared, The variable $SourceTableName used in the if condition is using values from global variable declared in the script.I am trying to copy portion of xml elements from the source file $MappletXmlName to another file $OutFileName which too have some elements.

sub GetMappletList { my ($TableNm,$ColumnNm,$DomainNm,$AlgoNm); my @MaskingAlgorithmList; my @MappletNode; my $MpltRefFile_Dir = shift; my $MappletXmlName; open GET_MAPPLET_LIST, "<","$Profiler_Dir/$MpltRefFile_Dir/Inve +ntory.rpt" or die "ERROR : Couldn't Open $Profiler_Dir/$MpltRefFile_D +ir/Inventory.rpt $!"; while (my $InvtoryCol = <GET_MAPPLET_LIST> ) { chomp $InvtoryCol; ($TableNm,$ColumnNm,$DomainNm,$AlgoNm) = split(/ +,/,$InvtoryCol); if ($TableNm =~ /$SourceTableName/) { $MappletXmlName = "$Mapplet_Dir/$AlgoNm. +XML"; my $MpltParser = XML::LibXML->new(); my $MpltXml = $MpltParser->parse_file("$ +MappletXmlName"); my $TargetXml = $MpltParser->parse_file( +"$OutFileName"); my @MappletNode = $MpltXml->findnodes('/ +POWERMART/REPOSITORY/FOLDER/MAPPLET'); for my $node (@MappletNode) { $TargetXml->appendChild +($node); #print $node->toString( +2); } } } close(GET_MAPPLET_LIST); }

    Again, what steps have you done to ensure that the file you give to ->parse_file exists and contains valid XML?

    Maybe it helps to print out $MappletXmlName and $OutFileName. Also, $AlgoNm seems to play a part in constructing the filename.

      Here is my updated code, i am able to print the exact node and associated sub elements i want to copy but how can i write the content of $node which is also getting printed in the output to the target file

      sub GetMappletList { my $Target_node; my ($TableNm,$ColumnNm,$DomainNm,$AlgoNm); my @MaskingAlgorithmList; my @MappletNode; my $MpltRefFile_Dir = shift; my $MappletXmlName; open GET_MAPPLET_LIST, "<","$Profiler_Dir/$MpltRefFile_Dir/Inve +ntory.rpt" or die "ERROR : Couldn't Open $Profiler_Dir/$MpltRefFile_D +ir/Inventory.rpt $!"; while (my $InvtoryCol = <GET_MAPPLET_LIST> ) { chomp $InvtoryCol; ($TableNm,$ColumnNm,$DomainNm,$AlgoNm) = split(/ +,/,$InvtoryCol); if ($TableNm =~ /$SourceTableName/) { print " The Workflow xml nme is $OutFile +Name\n"; $MappletXmlName = "$Mapplet_Dir/$AlgoNm. +XML"; print "The Dir name is $MappletXmlName\n +"; my $MpltParser = XML::LibXML->new(); my $TargetXml = $MpltParser ->parse_file +("$OutFileName"); my $MpltXml = $MpltParser->parse_file("$ +MappletXmlName"); my @MappletNode = $MpltXml->findnodes( +'//MAPPLET'); for my $node (@MappletNode) { print $node->toString(1 +); } } } close(GET_MAPPLET_LIST); }

      The source file content is given below

      <?xml version="1.0" encoding="Windows-1252"?> <!DOCTYPE POWERMART SYSTEM "powrmart.dtd"> <POWERMART CREATION_DATE="01/24/2014 18:27:23" REPOSITORY_VERSION="181 +.90"> <REPOSITORY NAME="xyz" VERSION="181" CODEPAGE="MS1252" DATABASETYPE="O +racle"> <FOLDER NAME="DM_POC" GROUP="" OWNER="Administrator" SHARED="NOTSHARED +" DESCRIPTION="" PERMISSIONS="rwx---rwx" UUID="c08574eb-cdf5-4bd1-bda +0-d08519348c79"> <MAPPLET DESCRIPTION ="" ISVALID ="YES" NAME ="mplt_Key_Lkp_NID" O +BJECTVERSION ="1" VERSIONNUMBER ="1"> *****----THERE ARE COUPLE of OTHER SUB ELEMENTS WHICH ARE NOT GIVEN HE +RE------**** </MAPPLET> </FOLDER> </REPOSITORY> </POWERMART>

      The Target xml file content looks like the below one

      I want to copy everything between the tags <MAPPLET> </MAPPLET> from source xml to target xml file and the copied content should be placed in the target, between <FOLDER> </FOLDER> tags

      I am totally lost myself in finding correct solution to make this work, Please advise me how can i fix it?
