CSV Map Configuration

   <map id="Map04" enabled="Y" description="GEN Comma Separated Variables">
        <input id="in1" description="Read GEN Comma Separated Variables">

            <XSLT>CSV_to_XML_Example.xsl</XSLT>

        <output id="out1" enabled="Y" description="Write XML Example">

    </map>

The CSV input connector uses the OpenCSV library and requires very little configuration. The are a pair of settings which you should review 

 <optionDelimeter>^</optionDelimeter>

and 

 <csvOptions>separator=,^quote="</csvOptions>

In the <csvOptions>separator=,^quote="</csvOptions> element you will see that 2 values are set, separator and quote. These 2 settings are separated by a delimiter which happens to be **^** in this example. However if by some unfortunate coincedence your CSV file uses that character as a value separater then you might need to use a different delimited in the configuration - which is where the `<optionDelimeter>^</optionDelimeter>` can be used.

NOTE that if you don't want a quote character this should be represented as shown below with _none_ used as the value. 

 <csvOptions>separator=,^quote=none</csvOptions>
