Mapping to Variables

Mapping to Variables

You can map an anchor to a data holder that is an XML element, an XML attribute, or a variable. The variable option is useful if you want to use the data in a subsequent processing step, but you do not want to include the raw data in the Parser output.
For example, suppose you want to extract several numbers from a source document and output their sum in the XML. You do not want the individual numbers in the output. You can map the
Content
anchors that retrieve the numbers to variables, and use a
CalculateValue
action to compute and output the sum.
You might also map to a variable that you use in a subsequent anchor, for example, to define a dynamic search text for a
Marker
anchor.
