Error: It was detected that 'sites' has no namespace, but components with no target namespace are not referenceable from schema document

阅读更多关于 Error: It was detected that 'sites' has no namespace, but components with no target namespace are not referenceable from schema document

问题 I have been working on this "advanced" schema for days with the flu and I cannot figure out why it keeps telling me that "sites" is not found. I re-read the chapter and even created a copy to experiment with (which worked before) and I do not understand. I am trying to import and combine schemas and I am not sure how to get it to work properly... Here are the errors: Ln 16 Col 84 - cvc-elt.1: Cannot find the declaration of element 'sites'. 1 Errors [Xerces-J 2.9.1] Validating XML Schema

WCF Versioning : Update Attribute Namespaces and Support Previous Namespaces

阅读更多关于 WCF Versioning : Update Attribute Namespaces and Support Previous Namespaces

问题 I have three WCF services (.svc) which generate .wsdl references for SOAP messages. Given that part of the namespace needs to change for all ServiceContract, OperationContract, DataContract attributes, for example [DataContract(Namespace = "http://old.com.au/types/")] to [DataContract(Namespace = "http://new.com.au/types/")] How is it that I can still support clients which have the old service reference (without them needing to update, because maybe they wont have time to update immediately)

问题 I am forced to fight with an external XML and I do not understand what is the difference between namespace and prefix in a XML file. I mean, I am using namespace and name of the label to get a value in this file with Linq library. But I do not know the difference between these. -<a:RoutePointsMeteoData z:Id="31" z:Size="10"> -<b:anyType z:Id="32" i:type="a:WaypointFLMeteoData"> <a:DevISA>0</a:DevISA> <a:DisplayTemperatureType>IsaDev</a:DisplayTemperatureType> <a:RelatedRoutePointName

问题 I am using lxml to parse XML from an external service that has namespaces, but doesn't register them with xmlns .

Why is an XML attribute without XMLNS prefix not equal to a prefixed attribute with same local name?

阅读更多关于 Why is an XML attribute without XMLNS prefix not equal to a prefixed attribute with same local name?

问题 When the default namespace and a prefixed namespace resolves to the same namespace URI, why is an attribute with no prefix not equal to a prefixed attribute, when both have the same local name? The "Namespaces in XML" specification just says it's so, but it's very short on why. Anyone knows why it's like this? Excerpt from section "6.3 Uniqueness of Attributes" at http://www.w3.org/TR/xml-names11/#uniqAttrs : For example, each of the bad empty-element tags is illegal in the following: <!--
