STRING expressions return text strings. They are used to manipulate non-numeric data. The STRING REPLACE expression returns a string where sections of the string have been replaced by another string.

The replacement occurs by taking an input string from a sub-expression, and replacing all occurrences of a sub-string specified by a TARGET expression node, with a replacement sub-string, specified by a REPLACEMENT expression node. The sub-expression may be a PROPERTY or a STRING expression.

See the EXPRESSION element for DTD and attribute information.
