Syntax

DQEXTTOKENGET (extraction-char, 'token', 'extraction-definition', ' <,'locale'> )

Required Arguments

extraction-char: specifies a character constant, variable, or expression that contains the value that is the extraction character value from which the value of the specified token is returned.

To determine how the extraction definition inserts delimiters, use the DQEXTINFOGET function.

token: the name of the token that is returned from the extraction value. The token must be enabled by the specified extraction definition

extraction-definition: the name of the extraction definition. The definition must exist in the locale that is used. The extraction definition must be the same as the extraction definition that originally extracted the EXTRACTION-CHAR value.

Optional Argument

locale: specifies a character constant, variable, or expression that contains the locale name.

Default:The default locale is the first locale in the locale list. If no value is specified, the default locale is used.

Details

The DQEXTTOKENGET function returns the value of the specified token from a previously extracted character value.

Example

The following example extracts a character value with the DQEXTRACT function and extracts two of the tokens with the DQEXTTOKENGET function.

extValue=dqExtract('Mr. James Joseph Westly', 'NAME', 'ENUSA');
prefix=dqExtTokenGet(extValue, 'Name Prefix', 'NAME', 'ENUSA');
given=dqExtTokenGet(extValue, 'Given Name', 'NAME', 'ENUSA');

After these function calls, the value of prefix is Mr. and the value of given is James.
