how can we extract the file extension of a file using ant script?

Question

The scenario is as follows:

Therea are three files :

test.xls test.txt test.doc

I am working with mqfte right now. When these files are transferred to another location the filenames must be as below :

result_xls.txt result_txt.txt result_doc.txt

Could anyone help on this?

Can this filename renaming done with ant scripts?

Try this:

<target name="test">
  <copy todir="dest">
    <fileset dir="src">
      <include name="test*"/>
    </fileset>
    <globmapper from="test.*" to="result_*.txt"/>
  </copy>
</target>

Input:

  $ find src
  src
  src/test.doc
  src/test.txt
  src/test.xls

Output:

  $ find dest/
  dest/
  dest/result_doc.txt
  dest/result_txt.txt
  dest/result_xls.txt

When i use the following code after a filecopy task in same target with a filecopy task, it is not working. Note the outcome property is defer in filecopy. is the problem due to outcome=defer. – trilawney May 30 '11 at 13:28
I am transferring the file from the source to dest. After reaching the destination i should rename it in the same folder itself. – trilawney May 30 '11 at 13:39

Sure, you can use the Move Ant Task http://ant.apache.org/manual/Tasks/move.html

You mean i should use a glob mapper?. Should there be three different targets? How can i extract the file extension for each file? – trilawney May 26 '11 at 10:58
I guess I would have tried the regexp mapper instead of glob, http://ant.apache.org/manual/Types/mapper.html – Karl-Bjørnar Øie May 26 '11 at 11:06
tale a look at sudocode's answer, seems he have solved your problem right there :-) – Karl-Bjørnar Øie May 26 '11 at 11:51
