Olá tenho que consumir um WebService utilizando apenas javascript

Encontrei um plugin (jqSOAPClient) do JQuery que faz isto...
Para teste eu procurei um WebService de exemplo na internet e o testei com o soapUI, funcionou sem problemas mas quando fui utilizar
O caso é que quando tento usar plugin para consumir o WS, ele gera o xml perfeitamente mas na hora de submeter a requisição ajax post gera um erro:

No firefox:
---------------------------
thrownError:
xhr.status: 0
xhr.responseText:
xhr.statusText: error

Internet Explorer
---------------------------
thrownError: No Transport
xhr.status: 0
xhr.responseText: undefined
xhr.statusText: error

Segue abaixo meu código, se alguém puder me ajudar:
index.html
