所以，當你使用wash_out寶石Rails和客戶端發送壞XML，反應是這樣的：wash_out解析故障：SOAP錯誤，而不是HTML錯誤
<html>…
<body>
<h1>REXML::ParseException</h1>
…
取而代之的是正確的SOAP響應，像這樣：
<soap:Body>
<soap:Fault>
<faultcode>soap:Client</faultcode>
…
我第一次嘗試修補wash_out本身。我設法在其測試中重現了 REXML :: ParseException，但後來發現我的沮喪 Rails實際上在bad_out之前解析（並且爆炸）了不良的XML，然後012_觸及了參數。
那麼，wash_out gem應該如何鉤入Rails，以便它可以解救那些異常，僅限於它擁有的路由？
這是我們必須合作的回溯。我很肯定有它的一些 點是天造地設掛接到，但我還不知道其中：
