You can export the name of a column in a CDATA section using
the syntax <![CDATA[columnname]]>.
You can export the value of a column using the syntax <![CDATA[~t columnname]]>.
The ~t is used to introduce a expression. You can also use an expression
such as ~t columnname*columnname to
export a computed value to the XML.
You can import a value into a column using the syntax <![CDATA[ columnname]]>.
Note that this syntax in a template has different results for import
and export: it imports the column value but exports the column name.
You cannot import an XML file that has a ~t expression in a CDATA section.
Everything else inside a CDATA section is ignored by the parser.
If text contains characters such as less than or greater than signs
(< or >) or ampersands (&) that are significant to the parser,
it should be defined as a CDATA section. A CDATA section starts
with <![CDATA[ and
ends with ]]>. CDATA
sections cannot be nested, and there can be no white space characters inside
the ]]> delimiter—for
example, you cannot put a space between the two square brackets.
<![CDATA[ do not parse me ]]>
This syntax in an export template exports the value of the column emp_salary:
<![CDATA[~t emp_salary]]>
This syntax in an import template imports the value of the column emp_salary:
<![CDATA[emp_salary]]>
