A regular expression datatype. Keeps an instance of the
compiled expression for speed purposes. This compiled
expression is lazily evaluated (it is compiled the first
time it is needed). The syntax is the dependent on which
regular expression type you are using. The system property
"ant.regexp.regexpimpl" will be the classname of the implementation
that will be used.
For jdk <= 1.3, there are two available implementations:
org.apache.tools.ant.util.regexp.JakartaOroRegexp (the default)
Based on the jakarta-oro package
org.apache.tools.ant.util.regexp.JakartaRegexpRegexp
Based on the jakarta-regexp package
For jdk >= 1.4 an additional implementation is available:
org.apache.tools.ant.util.regexp.Jdk14RegexpRegexp
Based on the jdk 1.4 built in regular expression package.
<regexp [ [id="id"] pattern="expression" | refid="id" ]
/>
