2.38. String Manipulation on Input Data

The CSV and fixed-length readers allow you to execute string manipulation functions on the input data before the data is converted into SAX events. The following functions are available:
  • upper_case: this returns the upper case version of the string.
  • lower_case: this returns the lower case version of the string.
  • cap_first: this returns the string with the very first word capitalized.
  • uncap_first: this returns the string with the very first word un-capitalized. It is the opposite of cap_first.
  • capitalize: this returns the string with all words capitalized.
  • trim: this returns the string without leading and trailing white-spaces.
  • left_trim: this returns the string without leading white-spaces.
  • right_trim: this returns the string without trailing white-spaces.
You can chain functions via the point separator. Here is an example: trim.upper_case
How you define the functions per field depends on the reader you are using.
