Part of string preceding character in delimiter set
Note: Many $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Parse function is the Before function. You might also find a more powerful solution in the StringTokenizer class or elements of the Sirius Regex implementation, such as the RegexSplit String function.
This function returns part of a given string: the characters after a specified or implied starting position and until a character in a delimiter set.
The $Parse function accepts three arguments and returns a string result that is a part of the first input string.
Syntax
%piece = $Parse(string, delims, [start_pos])
%piece is a piece of the first argument string.
The first argument is an arbitrary string.
The second argument is a string containing a set of delimiter characters.
The third argument is a starting position in the first argument string and has a default of 1.
Examples
The following statement would set %JUNK to WASTE NOT:
%JUNK = $Parse('WASTE NOT(WANT|NOT', '(|')
The statement below would set %JUNK to WASTE NOT(WANT:
%JUNK = $Parse('WASTE NOT(WANT|NOT', '|')
The following statement would set %JUNK to E NOT(WANT:
%JUNK = $Parse('WASTE NOT(WANT|NOT', '|', 5)
$Parse returns the entire first argument string if none of the delimiter characters are found. The matching function which retrieves the part of the string after the delimiter is $ParseX.
