Soap response, not well formed XML, no XOP parts l

问题:

I am consuming a web service in which I send off a request with an attachment and we receive a response from the server with various information. I have documented some problems with getting the request together in another question Adding an attachment to SOAP request but this bit has been resolved and now another problem has cropped up on the response.

We receive the response ok but an error is thrown stating:

Response is not well-formed XML.

The InnerException is:

WSE1608: No XOP parts were located in the stream for the specified content-id: <rootpart*[e-mail]>

The xml that is returned looks like:

--uuid:36875c60-630c-4e23-9e74-f9a9c7547fc7
Content-Type: application/xop+xml;charset=utf-8;type="text/xml";

I'm assuming this is an error due to the MIME parts, but how should this be handled?

Might I just add that this is the exact same XML returned in SoapUI and is the expected returned XML. Also, I might add that WSE is required for 2 reasons, because the third party developer of the web service refuses to change their working methods, and we also have a reliance on VS 2005 and therefore can't utilise WCF, espaecially with a deadline hanging over us.

回答1:

I don't know if it was an oversight when creating the post, but if the response does indeed have two spaces before the <?xml?> declaration, then that is the syntax error. If an xml declaration occurs, it MUST be the first thing in the document, nothing else (even whitespace) first.

http://www.w3.org/TR/REC-xml/#sec-prolog-dtd

Removing those spaces, the document looks well-formed, so I don't know what else it would be.

回答2:

Because of the first line, your XML will only be a valid if it's stored and opened in UTF-8 format. If you were to save this into notepad, say, and save it as "sample.xml", when you open it in Internet Explorer it will display it as a well formed XML.

However, if you were to load this response, in, say, a Unicode string and feed it to an XML parser, it will complain that your string is Unicode whilst the content is UTF-8.

One simple solution is to strip the line before feeding it to your XML parser. This will give you initial success, but, ultimately, for correctness, if you expect to have internationalization, you ought to be providing your content to your XML parser as a byte stream.

回答3:

you can make use of string operators to just extract the 2 lines containing xml code. for instance if you are using javascript you would

• use indexOf("<?xml") to obtain the start of xml code in the string (the one that containt the full response)
• use lastIndexOf("--uuid") to obtain the end of xml code
• calc lastIndexOf("--uuid") - indexOf("<?xml") to obtain the length of code
• finally use substr(xmlstart, xmllength) to obtain xml part of the response

all of this needs to be done after you receive response and before you parse it as xml

if you don't use javascript you can do the same by using regexp

in the even worse case, if your environment doesn't support any of the things i said, you can go for an old way: read line by line , when you first find a "<" as first character, save that line, read one more and stop.
