0008 How to Convert XML into CSV

This Example Demonstrates how to convert multiple XML files into CSV files

Here is an XML source example

                    <Table>
<Record>
<ID>1</ID>
<Company>James Bond Production</Company>
<Amount>13</Amount>
</Record>
<Record>
<ID>2</ID>
<Company>Green Cloud</Company>
<Amount>14</Amount>
</Record>
</Table>
                  

Here is XSLT used transformation:

                    <?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="UTF-8"/>
<xsl:template match="Table">
<xsl:text>ID,Company,Amount</xsl:text>
<xsl:text>&#xA;</xsl:text>
<xsl:for-each select="Record">
<xsl:value-of select="ID"/>
<xsl:text>,</xsl:text>
<xsl:value-of select="Company"/>
<xsl:text>,</xsl:text>
<xsl:value-of select="Amount"/>
<xsl:text>&#xA;</xsl:text>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
                  

Notes: We kept XSLT simple so it is easy to understand and modify if necessary.

Steps to follow

• Download and install Advanced ETL Processor [Link]
• Download and Unzip example [Link]
• Create a new transformation and open the .ats file

• Double click on the reader and select source XML Directory

• Repeat the process for the data writer
• Press the green arrow to run the transformation

How it works

1. Data Reader scans the source directory and loads files into memory one by one
2. The transformer converts files in memory into CSV using XSLT
3. Data Writer writes results into the target directory

• To amend the transformation double click on it

The transformation uses XML XSLT Transformation Function to convert XML to CSV and it also changes file name extension

• To change XML XSLT Transformation Function properties double click on it.

• Amend XSLT Transformation if necessary

• Press transform to see the result
