Subject Re: String Manipulation
Date Wed, 09 Jan 2008 15:36:45 GMT
Try this using the AntContrib <propertyregex> task:

<project name="test" default="test" basedir=".">
    <taskdef resource="net/sf/antcontrib/antcontrib.properties"/>
    <target name="test">
        <property name="string.in" value="foo/bar/fubar"/>
        <propertyregex
            property="string.out"
            input="${string.in}"
            regexp="/"
            replace="_"/>
        <echo message="The value is now &quot;${string.out}&quot;"/>
    </target>
</project>
