Uses a regular expression to select a sequence of child extractor results.
Child extractor results are referenced using @ExtractorName, where ExtractorName is the name of a child (or referenced) extractor. For example, consider the tabular data below, which represents information from a college transcript:
GE140 WORLD CIVILIZATION I 3.00 A 12.00
PSY212 GENERAL PSYCHOLOGY 3.00 A 12.00
GE185 HEALTH CONCEPTS 2.00 C 4.00
Three extractors are created for the Data Type:
The following collation expression could then be used to select the entire line:
@Course_No .*? @Decimal @Letter_Grade @Decimal
The expression can be further expanded to include group names, mapping values directly to table column names:
(?<Course_No>@Course_No)
(?<Description>[^\r]*?)
(?<Hours>@Decimal)
(?<Grade>@Letter_Grade)
(?<Points>@Decimal)
