Subject AW: Multiple properties into one property key
Date Wed, 19 May 2010 05:32:16 GMT
This works for me:

<project xmlns:ac="antlib:net.sf.antcontrib">

    <macrodef name="values2list">
        <attribute name="property"/>
        <attribute name="prefix"/>
        <attribute name="size"/>
        <attribute name="separator" default=","/>
        <sequential>
            <ac:var name="@{property}" value="${@{prefix}1}"/>
            <ac:for param="nr" begin="2" end="@{size}">
                <sequential>
                    <ac:var name="@{property}" value="${@{property}}@{separator}${@{prefix}@{nr}}"/>
                </sequential>
            </ac:for>
        </sequential>
    </macrodef>

    <property name="name.1" value="foo"/>
    <property name="name.2" value="foo"/>
    <property name="name.3" value="abc"/>
    <property name="name.4" value="xyz"/>

    <values2list property="list" prefix="name." size="4"/>

    <echo>List: ${list}</echo>
</project>
