XML Transformation in Informatica
The XML Parser transformation lets you extract XML data from messaging systems,
such as TIBCO or MQ Series, and from other sources, such as files or databases. The
XML Parser transformation functionality is similar to the XML source functionality,
except it parses the XML in the pipeline.

Types of XML Transformations
 XML Source Qualifier Transformation
 XML Parser Transformation
 XML Generator Transformation Overview

XML Source Qualifier Transformation:
It is an active transformation, as well as connected transformation . Just like the normal Source
Qualifier Transformation we can use the XML Source Qualifier Transformation by dragging an
XML source definition to the Mapping Designer workspace or by manually creating one. The source
definition needs to be connected to the target via XML Source Qualifier Transformation. This
Source qualifier defines the data elements that the Integration Service reads when it executes a
session. XML Source Qualifier has one input or output port for every column in the source. If you
remove an XML source definition from a mapping, the Designer also removes the corresponding
XML Source Qualifier transformation.

XML Parser Transformation
It’s an also active transformation, as well as Connected. We use an XML Parser transformation to
extract XML inside a pipeline and then pass this to the target. The XML is extracted from the source
systems such as files or databases. The XML Parser transformation reads XML data from a single
input port and writes data to one or more output ports.

XML Generator Transformation Overview:
It’s an also active transformation, as well as connected. We use XML Generator Transformation
Overview to create XML inside a pipeline. It reads data from source such as files and databases and
generates XML in the pipeline. The XML Generator transformation accepts data from multiple ports
and writes XML through a single output port.

Steps to performing XML Transformation:
In this example, we use source as a oracle and target as a XML.
 Import source table.
 Create target table in target designer. (if target same as a source then select Non-XML
Source).
 Drag and drop both source and target table in mapping designer window and then create
mapping and save it.
 Create workflow and assign task and specify connection and then save it.
 Preview data and check execution log.

Importing Source and Target Table
Step-1 Click on Start -> All Programs -> Informatica 9.0.1 -> Client -> Power
Center Client -> Power

Center Designer.

Step-2 Then Connect to Repository in Informatica Power Center Designer Right click on repository
name and click on Connect.

Step-3 Then go to Tools Menu and click on Source Analyzer to import source table. First create
ODBC Connection for the RDBMS Source.

Page 5

Step-4 And then go to Sources Menu in Informatica Power Center Designer. When you click on
Source, there are various option available for import source table but these four option are most
important to import source table,
 Import from Database - Import source table form RDBMS.
 Import from File - Import source table from Flatfile.
 Import from Cobol File - Import source table from Cobol source.
 Import XML Definition - Import source table from XML Source.

Step-5 Then click on Import from Database to import table from RDBMS Source database.

Page 6

Step-6 Select ODBC data source (first create ODBC Connection for RDBMS Source ) and then
specify Username, Owner name and password. Then click OK.

Page 7

Step-7 Right click on table and select Preview Data to View data of source table.

Step-8 Specify Username, Owner name and password. Then click connect.

Page 8

Step-9 Now go to Targets Designer in Informatica Power Center Designer and click on target menu.
In target menus also available various options and click on Import XML Definition.

Step-10 Here we have four options available in XML Definition, They are followings.
 Local File - Used local file as a target.
 URL - Give URL for Target
 Non-XML Sources - Used target as a source table.
 Non- XML Targets - Target table as a specified target table.

If your target table same as a source then select Non-XML Sources and select Source table.

Step-11 Select table and click on Open.

Step-12 Click Yes on open window..

Page 10

Step-13 Here some options for change XMLViews and creating and naming options so select options as your
target base and click OK.

Step-13 Here specify XML target table name.

Page 11

Step-11 Right click on table and select Preview Data to View the data.

Create Mapping

Step-1 Go to Mapping Designer and Create New Mapping and then name of mapping and
click OK.

Step-2 Then drag and drop source and target data in Mapping Designer.

Step-3 Then create mapping.

Page 13

Step-9 And then save it (ctrl+s) and check mapping is VALID.

Create Workflow
Step-1 Now go to Informatica Power Center Workflow Manager, and go to Tools menu and select
Workflow Designer.

Step-2 Now to create workflows, go to Workflows menu and select Create. Then Name of workflow
and click OK buttons.

Page 15

Step-3 Work flow Designer windows

Step-
4 Then create Task, Go to Tasks Menu and click Create.

Step-5 Now select session and insert Name of task.

Page 16

Step-6 Select Mapping to associate with the session.

Step-7 Workflow Designer Window.

Step-8 Now create flow B/W Workflow to Task. Select Link Task and link to start to s_XML. Link
task use to connect each workflow task(session). We can specify conditions with link to create
branches in the workflow. The Workflow Manager does not allow us to use links to create loops in
the workflow. Each link in the workflow can run only once.

Step-9 Work Designer Windows

Step-10 After that create relational connection for Oracle.

Step-11 Then specify Name, User Name, Password, Connection String and Attribute and then click
OK.

Page 18

Step-12 Now Configure Connection to Source and Target, Then Right Click on Filter and Edit, Then
Click Mapping tab and configure connection for your source and target table schema in oracle 11g
RDBMS. And then click OK.

Step-13 Select DBConnection for Source and Target Relation Database.

Page 19

Step-14 Set Property of Target Table. In property tab, we set property according to target
requirement. Here set target attribute and its value.

Page 20

Step-15 Now save (ctrl+s) this workflow and check it.

Page 21

Workflow Monitor and View Target Data
Step-1 Now Start Workflow, Right click on Workflow Designer Window and Click on Start
Workflow.

Step-2 Check session in Informatica PowerCenter Workflow Monitor.

Page 22

Step-3 Now check execution log.

Insert Script.

Target Load Summary.

Step-4 Now view data in Target.
