编辑wsdl以在asp.net中使用php web服务

Question

I'm having troubles to consume a php web service (which I can't modify) in my asp.net web api project. I tried to use "Add service reference" and "Add web reference", but still it's not working. I'm trying to find a solution that explain me how to edit or reconstruct the wsdl file (which I saved locally) so I can use it to consume the services. I've found another similar threads but without a solution that can help me. My problem is very similar to this one with .NET 2.0 but I'm using .NET 4.5:

Here is my errors message:

The document at the url file:xxx was not recognized as a known document type.
The error message from each known type may help you fix the problem:
- Report from 'XML Schema' is 'The root element of a W3C XML Schema should be <schema> and its     namespace should be 'http://www.w3.org/2001/XMLSchema'.'.
- Report from 'DISCO Document' is 'Discovery document at the URL file:xxx could not be found.'.
- The document format is not recognized.
- Report from 'WSDL Document' is 'There is an error in XML document (29, 6).'.
- The element was not expected in this context: <xsd:element     xmlns:xsd='http://www.w3.org/2001/XMLSchema'>..</xsd:element>.

The lines 28 to 30 are:

Thank you so much, I appreciate any suggestion.

Answer 1

Well, I solved! (I'm the same cxnv who asked this before but it seems I'm a very bad contributor according to the stackoverflow standards, I certainly don't know why, however... here is my answer anyway, I just didn't want to see it unsolved)

Fortunately, I found that The service wasn't using the WSDataArray complexType, so I deleted it in the wsdl and imported the modified the wsdl to my asp.net project (I still don't know what should I do if that WSDataArray were used). But then I was facing a problem because of the response was encoded with iso-8859-1, so I fixed it following this useful article, and voilà!!

The lesson is always avoid exposing web services in php!! The author of this article explain it very well:

"PHP is a weakly typed language (...), therefore reflection to generate WSDL files is impossible. This is a serious limitation for the applicability of PHP as a web services platform as it prevents PHP web services from having easy interoperability with clients written in other languages."

In this case I hadn't access to the service sources, but I hope my partner take into account this advice in the future.
