How to get ant JUnit result in user defined xml file name?

Question

How to get ant JUnit result in user defined xml file name? Junit (ant task) by default creates TEST-testcasename.xml for results, is there a way to change this xml file name? I am running same testcase multiple times for different browsers and currently the result for one browser is being overwritten by another browser's result.

Here is my code:

<target name="junit1">
<junit fork="true" forkmode="once" haltonfailure="false" logfailedtests="true">
<classpath refid="classpath.project"/>
<formatter type="xml"/>
<jvmarg value="-Dbrowser=${browser}"/>
<batchtest todir="${dir.report}">
    <fileset dir="${dir.src}">
        <include name="${testcase}"/>
    </fileset>
</batchtest>
</junit>

Why don't you just use a different output directory for each browser, or copy the output directory to another one when tests are finished?

<batchtest todir="${dir.report}/${browser}">

If you need all the files to be in the same directory, rename (or copy) them after each batch using the move (or copy) task with a glob mapper :

<mapper type="glob" from="TEST*.xml" to="${browser}-TEST*.xml"/>
