Merge files in some specific folder order using ant

[Happy S Singh]

I am merging files using below snippet.

But I wat to merge in some specific order of folder. I have folder structure like below

inputfiles
----folder1
----------folder1_delete
----------folder1_update
----------folder1_create
----folder2
----------folder2_delete
----------folder2_update
----------folder2_create

I want to merge files like It should merge all files of inputfiles/folder1/folder1_create then folder1_update and then folder1_delete.

<project default="mergefile">

<target name="mergefile">
    <merge tofile="merged.txt">
        <sourcefiles>
            <fileset dir="inputfiles"></fileset>  \\ path of inputfiles
        </sourcefiles>
    </merge>
</target>


    <macrodef name="merge">
        <attribute name="tofile"></attribute>
        <element name="sourcefiles"></element>

        <sequential>
            <tempfile property="temp.file" prefix="ant.merge." deleteonexit="true"></tempfile>

            <concat destfile="${temp.file}" fixlastline="true">
                <sourcefiles></sourcefiles>
            </concat>

            <copy file="${temp.file}" tofile="@{tofile}">

            </copy>
        </sequential>
    </macrodef>
</project>

What order do you want to merge into? Do you know the names of the files in advance?

[Happy S Singh]

I know the folder names.

inputfile folder in fixed

within

inputfile/XXXX/

, this forlder is dynamic but again within this folder

 inputfile/XXXX/XXXX_Delete
 inputfile/XXXX/XXXX_Update
 inputfile/XXXX/XXXX_Create

this will be fixed. Inside this folders,file names are unknown
