Mapping and transforming XML data

The following scenario creates a three-component Job that maps and transforms data from an XML source file Customer.xml, and generates an XML output flow which could be reused for various purposes, such as for an ESB request, in the future based on the XML tree structure of the file Customer_State.xml.

For more technologies supported by Talend, see Talend components.

These three components are:

tFileInputXML: provides the input data to tXMLMap.
tXMLMap: maps and transforms the received XML data flows into one single XML data flow.
tLogRow: displays the output data.

The content of the XML file Customer.xml is as follows:

<?xml version="1.0" encoding="ISO-8859-15"?>
<Customers>
	<Customer RegisterTime="2001-01-17 06:26:40.000">
		<Name>
			<id>1</id>
			<CustomerName>Griffith Paving and Sealcoatin</CustomerName>
		</Name>
		<Address>
			<CustomerAddress>talend@apres91</CustomerAddress>
			<idState>2</idState>
		</Address>
		<Revenue>
			<Sum1>67852</Sum1>
		</Revenue>
	</Customer>
	<Customer RegisterTime="2002-06-07 09:40:00.000">
		<Name>
			<id>2</id>
			<CustomerName>Bill's Dive Shop</CustomerName>
		</Name>
		<Address>
			<CustomerAddress>511 Maple Ave. Apt. 1B</CustomerAddress>
			<idState>3</idState>
		</Address>
		<Revenue>
			<Sum1>88792</Sum1>
		</Revenue>
	</Customer>
	<Customer RegisterTime="1987-02-23 17:33:20.000">
		<Name>
			<id>3</id>
			<CustomerName>Glenn Oaks Office Supplies</CustomerName>
		</Name>
		<Address>
			<CustomerAddress>1859 Green Bay Rd.</CustomerAddress>
			<idState>2</idState>
		</Address>
		<Revenue>
			<Sum1>1225.</Sum1>
		</Revenue>
	</Customer>
	<Customer RegisterTime="1992-04-28 23:26:40.000">
		<Name>
			<id>4</id>
			<CustomerName>DBN Bank</CustomerName>
		</Name>
		<Address>
			<CustomerAddress>456 Grossman Ln.</CustomerAddress>
			<idState>3</idState>
		</Address>
		<Revenue>
			<Sum1>64493</Sum1>
		</Revenue>
	</Customer>
</Customers>

The content of the XML file Customer_State.xml is as follows:

<?xml version="1.0" encoding="ISO-8859-15"?>
<customers>
	<customer id="1">
		<CustomerName>Griffith Paving and Sealcoatin</CustomerName>
		<CustomerAddress>talend@apres91</CustomerAddress>
		<idState>2</idState>
	</customer>
	<customer id="2">
		<CustomerName>Bill's Dive Shop</CustomerName>
		<CustomerAddress>511 Maple Ave.  Apt. 1B</CustomerAddress>
		<idState>3</idState>
	</customer>
</customers>
