<subst> Element

The <subst> element is a child of the <transform> step. This element specifies a Perl-like substitution pattern to apply as a transformation. One or more <subst> elements can appear as children of the <transform> element, but they cannot be used in conjunction with other child elements. When more than one <subst> element appears, they are applied sequentially.

All occurrences of the pattern in the input file are replaced, including multiple occurrences within a line.

For information about the supported syntax, see Java documentation (class java.util.regex.Pattern).
