xtract converts an XML document into a table of data values according to user-specified rules.
String constraints use case-insensitive comparisons.
Numeric constraints and selection arguments use integer values.
-num and -len selections are synonyms for Object Count (#) and Item Length (%).
-words, -pairs, and -indices convert to lower case.
