class	fixed	This attribute must assume the value it.greenvulcano.gvesb.gvdte.transformers.bin.bin2xml.CSVToXMLTransformer
name	required	Transformation name. The attribute's value cannot be null.
FieldDelimiter	required	CSV field delimiter. Default ','. The attribute's value cannot be null.
UseCDATA	required	Defines if the fields values must be enclosed in a CDATA section. The attribute's admitted values are: True False

CSV2XMLTransformation might contain the following sub-elements:

• Description
• TransformationAlias

How To

To add a new CSV2XMLTransformation go to the VulCon^® Core view. Expand the GVDataTransformation element and right clicking Transformation -> Insert after or Insert before -> CSV2XMLTransformation.

The following example shows the use of CSV2XMLTransformation to transform CDR data, passed in input as CSV files, into an XML.

There have been defined two Transformations and a SequenceTransformation which performs both:

<CSV2XMLTransformation FieldDelimiter="," UseCDATA="False"
          class="it.greenvulcano.gvesb.gvdte.transformers.bin.bin2xml.CSVToXMLTransformer"
          name="ERICSSON_cdrToXml" type="transformation"/>
<XSLTransformation DataSourceSet="Default"
          XSLMapName="DataHandler/Ericsson/CaMa/InsertCDRDataBis.xsl"
          class="it.greenvulcano.gvesb.gvdte.transformers.xslt.XSLTransformer"
          name="InsertCDRData" type="transformation"/>
<SequenceTransformation DumpInOut="true" Output="OUT2"
          class="it.greenvulcano.gvesb.gvdte.controller.SequenceTransformer"
          name="UpdateCDRData" type="transformation">
     <SequenceElement Input="IN" Output="OUT1" Transformer="ERICSSON_cdrToXml"/>
     <SequenceElement Input="OUT1" Output="OUT2" Transformer="InsertCDRData"/>
</SequenceTransformation>

The following dh-call operation has been defined in order to convert the input as CSV data into a XML that will be successively transformed for inserting or updating the read data into the database.

<dh-call class="it.greenvulcano.gvesb.virtual.datahandler.DataHandlerCallOperation"
         name="ChangeCDRToXML" type="call">
     <DBOBuilder class="it.greenvulcano.gvesb.datahandling.dbobuilder.DBOBuilder"
                 jdbc-connection-name="ds.gv_cama" make-dump="text"
                 name="ChangeCDRToXML" output-data="InsertOrUpdate"
                 type="dbobuilder">

                 <DHVariable name="format" value="#0.00"/>

                      values((select ID from MESSAGES where MMS_ID = ?),?,?,?,'',sysdate)
                 </statement>
                 <statement id="1" type="update">UPDATE cama.cdr_event
