passing xml attributes to ant build.xml file

I use Ant to build my swf output file. I have got in project directory (along with project src/*.as files) build.xml, package.config and directory.properties files. The package.config file is created outside by Nuget, so I need to rely on values in it:

<packages>
    <package id="Lib1" version="1.0" />
    <package id="Lib2" version="1.0" />
</packages>

now in build.xml I'm adding file:

<property file="package.config" />

then I need to include libraries (compiler.include-libraries) containing in their names package.id and package.version i.e.:

<include name="package.id" + "package.version" + ".swc" />

Unfortunately I can not do it this way. I should probably store packages attributes somewhere and then use it passing to name property in tag. Thanks in advance for any clue.

You probably want to have the package attributes in a .properties file. This will make your life easier with Ant, and won't require extra tools like XMLtask to scoop them out of the XML document you mentioned. Take a good read through Ant's documentation about how properties work. Properties get expanded from references that look like ${this}, and you don't need to concatenate things with the + sign like you're trying to do.

You'll end up writing something that looks more like this:

<include name="${package.id}${package.version}.swc"/>

One possible solution would be using xmlproperty task combined with script task using builtin (since Java 1.6.0_06) javascript engine.

Given xmlfile from Nuget :

<packages>
 <package id="Foo" version="1.0"/>
 <package id="Bar" version="1.0"/>
</packages>

Ant snippet using given xmlfile :

<project>

<xmlproperty file="yournugetfile.xml" collapseAttributes="true"/>

<!-- show properties from xmlpropertyfile -->
<echoproperties prefix="packages"/>

<!-- produce includes from those package properties -->
<script language="javascript">
<![CDATA[
 var pids = project.getProperty('packages.package.id').split(',');
 var pvers = project.getProperty('packages.package.version').split(',');
 var incl = "";
 for (i=0; i < pids.length; i++) {
  incl += pids[i] + pvers[i] + '.swc' + ',';
 }
 project.setProperty('cincludes', incl.substring(0, incl.length - 1));
]]>
</script>

<echo>$${cincludes} => ${cincludes}</echo>

<!-- demonstrate possible use -->
<echoxml>
 <compiler.library-path dir="some/path" append="true">
  <include name="${cincludes}"/>
 </compiler.library-path>
</echoxml>

</project>

output :

[echoproperties] #Ant properties
[echoproperties] #Tue May 20 16:37:54 CEST 2014
[echoproperties] packages.package=,
[echoproperties] packages.package.id=Foo,Bar
[echoproperties] packages.package.version=1.0,1.0
[echo] ${cincludes} => Foo1.0.swc,Bar1.0.swc
<?xml version="1.0" encoding="UTF-8"?>
<compiler.library-path append="true" dir="some/path">
  <include name="Foo1.0.swc,Bar1.0.swc" />
</compiler.library-path>
