Tree.dataProvider com XML complexo

Essa vai para um novo amigo.

Para construir a Tree foi usado o seguinte XML, para simular a saída produzida pela framework usada.

<?xml version="1.0" encoding="utf-8"?>
<tabela>
<faturamento>
<diafatura><![CDATA[00-00-0000]]></diafatura>
<diafatura><![CDATA[00-00-0000]]></diafatura>
<diafatura><![CDATA[00-00-0000]]></diafatura>
<diafatura><![CDATA[00-00-0000]]></diafatura>
<empresa><![CDATA[1]]></empresa>
<empresa><![CDATA[1]]></empresa>
<empresa><![CDATA[1]]></empresa>
<cliente><![CDATA[1]]></cliente>
<cliente><![CDATA[1]]></cliente>
<cliente><![CDATA[1]]></cliente>
<valor><![CDATA[15.00]]></valor>
<valor><![CDATA[15.00]]></valor>
<valor><![CDATA[15.00]]></valor>
<id><![CDATA[1]]></id>
<id><![CDATA[2]]></id>
<id><![CDATA[3]]></id>
</faturamento>
<empresas>
<id><![CDATA[1]]></id>
<id><![CDATA[2]]></id>
<codigo><![CDATA[1]]></codigo>
<codigo><![CDATA[1]]></codigo>
<razaoSocial><![CDATA[tal]]></razaoSocial>
<razaoSocial><![CDATA[tal]]></razaoSocial>
<cnpj><![CDATA[545]]></cnpj>
<cnpj><![CDATA[545]]></cnpj>
<observacao><![CDATA[obs]]></observacao>
<observacao><![CDATA[obs]]></observacao>
<created_at><![CDATA[00-00-000]]></created_at>
<created_at><![CDATA[00-00-000]]></created_at>
<updated_at><![CDATA[00-00-000]]></updated_at>
<updated_at><![CDATA[00-00-000]]></updated_at>
<lock_version><![CDATA[00-00-000]]></lock_version>
<lock_version><![CDATA[00-00-000]]></lock_version>
</empresas>
</tabela>

E o script Flex fica da seguinte forma.

<?xml version="1.0" encoding="utf-8"?>
