ant-contrib has propertyregex. You can use it in this case. Here is an example
build file:
<project name="test" basedir="." default="doit"
xmlns:ac="antlib:net.sf.antcontrib">
<property name="orig" value="010203"/>
<property name="theregex" value="^0([0-9])0([0-9])0([0-9])$$"/>
<target name="doit">
<ac:propertyregex property="first" input="${orig}"
regexp="${theregex}"
select="\1" override="true"/>
<ac:propertyregex property="second" input="${orig}"
regexp="${theregex}"
select="\2" override="true"/>
<ac:propertyregex property="third" input="${orig}"
regexp="${theregex}"
select="\3" override="true"/>
<echo>First is ${first}
Second is ${second}
Third is ${third}</echo>
</target>
</project>
