Print new char string in regexp under Java or ANT

Question

I have an ant target that calls the replaceregexp task

<target name="regexp.replace"> <replaceregexp file="${file.temp}" match="(.*)" replace="first operation on \1 second operation on \1" byline="true"/> </target> 

file.temp

 A1 A2 

desired result:

 first operation on A1 second operation on A1 first operation on A2 second operation on A2 

What to insert as a new char string to get the desired result in the ant replaceregexp parameter?

  replace="first operation on \1 %NEW_LINE% second operation on \1" 

Answer 1

The following works for me:

 <replaceregexp file="test.txt" match="(.*)" replace="first operation on \1${line.separator}second operation on \1" byline="true"/>
