followup =3D

the behaviour described in my first posting occurs with Windows2000, jdk 1.=
5.0_11
i checked with the same propertyfiles, means
  <xmlkey> </xmlkey>
  txtkey=3D *blank*
and antscript with isset condition on my private machine =3D
OpenSuse 11.1/64bit, jdk 1.6.0_13 and got equal ouput for all available ant=
 versions =3D

 [echo] Apache Ant version 1.6.5 compiled on June 2 2005
 [echo] ${xmlkey} =3D=3D ${xmlkey}
 [echo] ${txtkey} =3D=3D ${txtkey}
 [echo] xmlkey not set
 [echo] txtkey not set

 [echo] Apache Ant version 1.7.0 compiled on December 13 2006
 [echo] ${xmlkey} =3D=3D ${xmlkey}
 [echo] ${txtkey} =3D=3D ${txtkey}
 [echo] xmlkey not set
 [echo] txtkey not set

 [echo] Apache Ant version 1.7.1 compiled on June 27 2008
 [echo] ${xmlkey} =3D=3D ${xmlkey}
 [echo] ${txtkey} =3D=3D ${txtkey}
 [echo] xmlkey not set
 [echo] txtkey not set

i rechecked on Windows2000, jdk1.5.0_11

 [echo] Apache Ant version 1.6.5 compiled on June 2 2005
 [echo] ${xmlkey} =3D=3D ${xmlkey}
 [echo] ${txtkey} =3D=3D=20

 [echo] txtkey set and !=3D null

 [echo] Apache Ant version 1.7.0 compiled on December 13 2006

 [echo] ${txtkey} =3D=3D=20

 [echo] txtkey set and !=3D null

 [echo] Apache Ant version 1.7.1 compiled on June 27 2008
 [echo] ${xmlkey} =3D=3D ${xmlkey}
 [echo] ${txtkey} =3D=3D=20
 [echo] xmlkey not set
  [echo] txtkey set and !=3D null


and AIX 5.3.0.0, J2RE 1.5.0 IBM J9 2.3 AIX ppc-32

[echo] Apache Ant version 1.7.1 compiled on June 27 2008
[echo] ${xmlkey} =3D=3D ${xmlkey}
[echo] ${txtkey} =3D=3D
[echo] xmlkey not set
[echo] txtkey set and !=3D null

Conclusion =3D there seems to be a difference related to the handling
of txt- and xmlproperties on different platforms, maybe it's caused by jdk/=
jre ?

So i need to use a workaround like that, to check whether a property
isset or is blank =3D

<if>
  <!--<isset property=3D"xmlkey"/>-->
  <not>
    <or>
      <contains string=3D"${xmlkey}" substring=3D"$${"/>
      <equals arg1=3D"${xmlkey}" arg2=3D"" />
    </or>
  </not>
  <then>
    <echo>xmlkey set and !=3D null</echo>
  </then>
  <else>
    <echo>xmlkey not set</echo>
  </else>
</if>


Any other ideas ?
Should i open a bugreport ?


Regards, Gilbert

Hi,

found another oddity after upgrading to Ant 1.7.1,
regarding the handling of properties and xmlproperties.

<project name=3D"bla" default=3D"main" basedir=3D".">
  <!-- // Taskdefs -->
  <!-- Import AntContrib -->
  <taskdef resource=3D"net/sf/antcontrib/antlib.xml" />
  <!-- Taskdefs // -->

  <!-- // Properties -->
  <property file=3D"props.txt" />
  <xmlproperty file=3D"props.xml" keeproot=3D"false" />
  <!-- Properties // -->

  <target name=3D"main">
    <echo>${ant.version}</echo>
    <echo>$${xmlkey} =3D=3D ${xmlkey}</echo>
    <echo>$${txtkey} =3D=3D ${txtkey}</echo>
    <if>
      <isset property=3D"xmlkey"/>
      <then>
        <echo>xmlkey set and !=3D null</echo>
      </then>
      <else>
        <echo>xmlkey not set</echo>
      </else>
    </if>
    <if>
      <isset property=3D"txtkey" />
      <then>
        <echo>txtkey set and !=3D null</echo>
      </then>
      <else>
        <echo>txtkey not set</echo>
      </else>
    </if>
  </target


Testpropertyfiles
both xmlkey and txtkey are null

<?xml version=3D"1.0" encoding=3D"UTF-8"?>
<root>
  <xmlkey></xmlkey>
  <xmlfoo>bar</xmlfoo>
</root>

------

txtfoo=3Dbar
txtkey=3D


ant 1.6.5
     [echo] Apache Ant version 1.6.5 compiled on June 2 2005
     [echo] ${xmlkey} =3D=3D ${xmlkey}
     [echo] ${txtkey} =3D=3D=20
     [echo] xmlkey not set
     [echo] txtkey set and !=3D null

means txt and xmlproperty behave different
seems to be fixed now, as ant 1.7.1 gives the same
result for txt and xmlproperty =3D

ant 1.7.1
     [echo] Apache Ant version 1.7.1 compiled on June 27 2008
     [echo] ${xmlkey} =3D=3D=20
     [echo] ${txtkey} =3D=3D=20
     [echo] xmlkey set and !=3D null
     [echo] txtkey set and !=3D null


Testpropertyfiles=20
both xmlkey and txtkey are " "

<?xml version=3D"1.0" encoding=3D"UTF-8"?>
<root>
  <xmlkey> </xmlkey>
  <xmlfoo>bar</xmlfoo>
</root>

------

txtfoo=3Dbar
txtkey=3D *blank*

ant 1.6.5
     [echo] Apache Ant version 1.7.1 compiled on June 27 2008
     [echo] ${xmlkey} =3D=3D ${xmlkey}
     [echo] ${txtkey} =3D=3D=20
     [echo] xmlkey not set
     [echo] txtkey set and !=3D null

ant 1.7.1
     [echo] Apache Ant version 1.7.1 compiled on June 27 2008
     [echo] ${xmlkey} =3D=3D ${xmlkey}
     [echo] ${txtkey} =3D=3D=20
     [echo] xmlkey not set
     [echo] txtkey set and !=3D null


means there's a difference between the handling of txtproperties
and xmlproperties that existed in 1.6.5 and still exists in 1.7.1,
should be the same for both kind of properties, i would expect =3D
     [echo] ${xmlkey} =3D=3D=20
     [echo] ${txtkey} =3D=3D


Is that intended behaviour  or just a bug ?

Gilbert
