Part of string preceding character in delimiter set

Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is no direct OO equivalent for the $Parse function, but you might 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.

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.

Syntax

%PIECE = $Parse(string, delims, start_pos)

%PIECE is a piece of the first argument string.

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.
