Transform a delimited string to array or ItemGroup - msbuild

Question

I'm trying to create a MSBuild target to post-process assemblies through a custom executable (e.g. convert.exe).
The target receives a semi-colon ; separated list of assemblies as Input and I would like to batch Exec.
<Target Name="_CollectAssemblies" DependsOnTargets="ResolveReferences">
<ItemGroup>
<_Assemblies Include="#(ReferencePath);#(CopyLocalFiles);#(ResolvedDependencyFiles);#(ReferenceDependencyPaths);$(TargetPath)" />
</ItemGroup>
</Target>
<Target Name="_ConvertFiles" DependsOnTargets="_CollectAssemblies"
Inputs="#(_Assemblies)">
<Exec Command="echo #(_Assemblies)" />
<!--<Exec Command="$(MSBuildThisFileDirectory)convert.exe #(_Assemblies)" />-->
</Target>
The Exec command outputs, echo Assembly1.dll;Assembly2.dll;Assembly3.dll;.
How do I transform the Input so that I can process each assembly individually?
e.g.
echo Assembly1.dll
echo Assembly2.dll
echo Assembly3.dll
So far I have tried:
<Target Name="_ConvertFiles" DependsOnTargets="_CollectAssemblies"
Inputs="#(_Assemblies)">
<ItemGroup>
<_SplitAssemblies Include="$(_Assemblies.Split(';'))" />
</ItemGroup>
<Exec Command="echo %(_SplitAssemblies.Identity)" />
</Target>

Answering my own question. MSBuild already had a way of batching the items (as I thought!).
<Target Name="_ConvertFiles" DependsOnTargets="_CollectAssemblies"
Inputs="#(_Assemblies)">
<ItemGroup>
<_ConvertAssemblies Include="#(_Assemblies)"/>
</ItemGroup>
<Exec Command="$(MSBuildThisFileDirectory)convert.exe %(_ConvertAssemblies.Identity)" />
<Error Text="Stop" />
</Target>
