XPathMessageContext Class
Defines several XPath functions and namespace mappings commonly used when evaluating XPath expressions against SOAP documents.
System.Xml::XmlNamespaceManager
System.Xml.Xsl::XsltContext
System.ServiceModel.Dispatcher::XPathMessageContext
Assembly: System.ServiceModel (in System.ServiceModel.dll)
The XPathMessageContext type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | XPathMessageContext() | Creates an instance of XPathMessageContext. |
![]() | XPathMessageContext(NameTable) | Initializes a new instance of the XPathMessageContext class with the specified NameTable. |
| Name | Description | |
|---|---|---|
![]() | DefaultNamespace | Gets the namespace URI for the default namespace. (Inherited from XmlNamespaceManager.) |
![]() | NameTable | Gets the XmlNameTable associated with this object. (Inherited from XmlNamespaceManager.) |
![]() | Whitespace | Gets a value that indicates whether to include white space nodes in the output. (Overrides XsltContext::Whitespace.) |
| Name | Description | |
|---|---|---|
![]() | AddNamespace | Adds the given namespace to the collection. (Inherited from XmlNamespaceManager.) |
![]() | CompareDocument | Compares the base Uniform Resource Identifiers (URIs) of two documents based upon the order the documents were loaded by the XSLT processor. (Overrides XsltContext::CompareDocument(String, String).) |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetEnumerator | Returns an enumerator to use to iterate through the namespaces in the XmlNamespaceManager. (Inherited from XmlNamespaceManager.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetNamespacesInScope | Gets a collection of namespace names keyed by prefix which can be used to enumerate the namespaces currently in scope. (Inherited from XmlNamespaceManager.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | HasNamespace | Gets a value indicating whether the supplied prefix has a namespace defined for the current pushed scope. (Inherited from XmlNamespaceManager.) |
![]() | LookupNamespace | Gets the namespace URI for the specified prefix. (Inherited from XmlNamespaceManager.) |
![]() | LookupPrefix | Finds the prefix declared for the given namespace URI. (Inherited from XmlNamespaceManager.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | PopScope | Pops a namespace scope off the stack. (Inherited from XmlNamespaceManager.) |
![]() | PreserveWhitespace | Evaluates whether to preserve white space nodes or strip them for the given context. (Overrides XsltContext::PreserveWhitespace(XPathNavigator).) |
![]() | PushScope | Pushes a namespace scope onto the stack. (Inherited from XmlNamespaceManager.) |
![]() | RemoveNamespace | Removes the given namespace for the given prefix. (Inherited from XmlNamespaceManager.) |
![]() | ResolveFunction | Resolves a function reference and returns an T:System.Xml.Xsl.IXsltContextFunction that represents the function. (Overrides XsltContext::ResolveFunction(String, String, array<XPathResultType>).) |
![]() | ResolveVariable | Resolves a variable reference and returns an IXsltContextVariable that represents the variable. (Overrides XsltContext::ResolveVariable(String, String).) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
The XPath engine has full XPath context support and uses the .NET Framework's XsltContext class in the same way that XPathNavigator does to implement this support. XsltContext is an abstract class that allows developers to implement custom XPath function libraries and declare XPath variables. XsltContext is an XmlNamespaceManager and thus also contains the namespace prefix mappings.
The filter engine implements an XsltContext named XPathMessageContext. XPathMessageContext defines custom functions that can be used in XPath expressions and it declares several common namespace prefix mappings.
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
