使用JavaScript从多部分XML SOAP响应中打开PDF

Question

我正在尝试从多部分XML soap响应中打开pdf。

我正在使用的FrameWork是Angular 6

这是我的肥皂要求

 var xmlhttp = new XMLHttpRequest();
 xmlhttp.open('POST', 'url', true);
 strRequest =
 '<?xml version="1.0" encoding="UTF-8"?>' +
 '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="urn://ecm.rmv.com/document/2013/06/01">' +
     '<soapenv:Header/>' +
     '<soapenv:Body>' +
         '<ns:searchDocumentRequest>' +
             '<ns:repositoryId>CrashReport</ns:repositoryId>' +
             '<ns:actorId>CrashPortal</ns:actorId>' +
             '<ns:documentType>CrashReport</ns:documentType>' +
             '<ns:properties>' +
             '<ns:property name="CrashDocNum"/>' +
             '</ns:properties>' +
             '<ns:filters>' +
                 '<ns:filter>' +
                     '<ns:condition property="CrashDocNum" operator="eq" value="PR201104900247"/>' +
                 '</ns:filter>' +
             '</ns:filters>' +
             '<ns:options>' +
                 '<ns:option name="retrieveContent">true</ns:option>' +
             '</ns:options>' +
         '</ns:searchDocumentRequest>' +
     '</soapenv:Body>' +
 '</soapenv:Envelope>'
xmlhttp.setRequestHeader('Content-Type', 'text/xml; charset=utf-8');
xmlhttp.setRequestHeader('SOAPAction', 'searchDocument');
xmlhttp.send(strRequest);

以下是部分响应：

我尝试了多种方法，但似乎无济于事：

注意：如果我将回复保存在文本文件中，然后将扩展名更改为pdf，则会显示pdf。

我在网上阅读了很多有关将其转换为Base64的显示代码，但是鉴于肥皂响应的回馈，我不知道是否可以这样做。

在上一次尝试中，我试图使用边界来分割xml，以获取以％PDF-1.6 开头的部分。拆分后，我运行下面的代码下载文件。

downloadReponse(doc_data) {
    var newBlob = new Blob([doc_data], {type: "application/pdf"})
    var url = window.URL.createObjectURL(newBlob);
    var link = document.createElement('a');
    link.href = url;
    link.download = "file.pdf";

    link.click();
    setTimeout(function () {
      URL.revokeObjectURL(url);
    }, 10000);
}

这确实下载了文件，但是当我打开它时，pdf会以三个空白页面打开。本来我想让它在新标签页中打开，但是我在网上找到的代码仅适用于Base64。
