Ant & how to parse a properties file to echo back the values

Question

I have a properties file that I want to echo out the values

<HSMKeys>
<Key domain="default" value="TestA" />
<Key domain="fixed" value="TestB" /> 
</HSMKeys>

as

[echo] domain=default value=TestA
[echo] domain=fixed value=TestB

How can I do this, ie loop over the properties file and have the two variables that would be in the echo.

I have tried the following

<for list="${HSMKeys.Key.domain}" param="domain">
<sequential>
<echo>domain=@{domain}</echo>
</sequential>
</for>

ie I can only get at one attribute value at a time, not both at once.

Thanks.

Answer 1

That's not a properties file. Properties files are key/value pairs. How are you populating list?

a property file ant will understand will look like:

domain.default=TestA
domain.fixed=testB

I recommend avoiding ant-contrib at all costs... what are you really trying to do? you could simply use echoproperties

<project name="test" default="echo" basedir=".">

    <property file="build.properties" />

    <target name="echo" >
        <echoproperties prefix="domain."/>
    </target>

</project>

As @thekbb has stated this is not a properties file, however, ANT supports the parsing of XML files as properties.

<project name="demo" default="print">

  <xmlproperty file="properties.xml"/>

  <target name="print">
    <echoproperties prefix="HSMKeys."/>
  </target>

</project>

Produces the following output:

print:
[echoproperties] #Ant properties
[echoproperties] #Tue Dec 03 23:44:14 GMT 2013
[echoproperties] HSMKeys.Key=,
[echoproperties] HSMKeys.Key(domain)=default,fixed
[echoproperties] HSMKeys.Key(value)=TestA,TestB

May not be exactly what you need but has the advantage of not requiring additional jars like Ant-contrib.
