Support for xml namespaces in XPathMatcher

[cal-schleupen]

We have round about 4800 WCF Services in our landscape, thus this faker is really helpful. In order to write more easy request body matchers I would like to write more easy xpath expressions using the xpath matcher as follows:

{
    "Title": "wcf test",
    "Request": {
        "Path": {
            "Matchers": [
                {
                    "Name": "WildcardMatcher",
                    "Pattern": "/MyService.svc"
                }
            ]
        },
        "Methods": [
            "post"
        ],
                "Headers": [
                    {
                        "Name": "Content-Type",
                        "Matchers": [
                            {
                                "Name": "WildcardMatcher",
                                "Pattern": "text/xml; charset=utf-8",
                                "IgnoreCase": true
                            }
                        ],
                        "IgnoreCase": true
                    },
                    {
                        "Name": "SOAPAction",
                        "Matchers": [
                            {
                                "Name": "WildcardMatcher",
                                "Pattern": "*urn:https://MyService/Query*",
                                "IgnoreCase": true
                            }
                        ],
                        "IgnoreCase": true
                    }
                ],
        "Body": {
            "Matcher": {
                "Name": "XPathMatcher",
                "Pattern": "/s:Envelope/s:Body/q:QueryRequest",
                "XmlNamespaceMap": [
                    { 
                        "Prefix": "s",
                        "Uri": "http:https://schemas.xmlsoap.org/soap/envelope/"
                    },
                    { 
                        "Prefix": "i",
                        "Uri": "http:https://www.w3.org/2001/XMLSchema-instance"
                    },
                    { 
                        "Prefix": "q",
                        "Uri": "urn:https://Schleupen.AS.MT.BIB.Buecher.BuchQueryService_3.1"
                    }
                ]
            }
        }
    },
    "Response": {
        "StatusCode": 200,
        "Body": "<s:Envelope xmlns:s=\"http:https://schemas.xmlsoap.org/soap/envelope/\"><s:Body><QueryResponse xmlns=\"urn:https://MyService\"></QueryResponse></s:Body></s:Envelope>",
        "Headers": {
            "Content-Type": "text/xml"
        }
    }
}

This implementation handles this so that

<s:Envelope xmlns:s="http:https://schemas.xmlsoap.org/soap/envelope/"><s:Header></s:Header><s:Body><QueryRequest xmlns="urn:https://MyService"><MaxResults i:nil="true" xmlns:i="http:https://www.w3.org/2001/XMLSchema-instance"/><Restriction i:nil="true" xmlns:i="http:https://www.w3.org/2001/XMLSchema-instance"/><SearchMode i:nil="true" xmlns:i="http:https://www.w3.org/2001/XMLSchema-instance"/></QueryRequest></s:Body></s:Envelope> 

matches for example.

Yes, I can use 'local-name()' etc. but I think this way it is more easy.

Thank you for this addition.

I did add some review comments, can you please take a look?

Hi Stef,

thanks a lot for reviewing it so fast! I'm really impressed and I like WireMock.NET a lot. It is also well done under the hood. This weekend I am a little bit busy with my family, but I'll fix it not later than on Monday. Hopefully today ;-)

I am really happy that you could take a look at my pull request!

Kind regards,
Carsten

@cal-schleupen
Thank you.

I'll merge this and create a new NuGet.
