This interface controls all SOAP messages. It permits easy construction of a message, typically through encoding of parameters and certain properties settable on this interface or through deserialization of a transport stream. It permits easy processing of a message typically through decoding of parameters and certain properties available on this interface. It also encapsulates protocol information interpreted by the transport.

Attributes
An optional URI that can be used to add a SOAPAction HTTP header field. If this attribute is NULL (the default case), no SOAPAction header will be added.
attribute
AString
actionURI
A convenience attribute to obtain the DOM element representing the SOAP body from the envelope. DOM methods may be used to access, add, or modify attributes or elements of the body. If the envelope attribute is null or does not contain a SOAP body element type, then this will be null.
readonly attribute
nsIDOMElement
body
The primary encoding of the message, which is established at the envelope and used unless overridden. By default, this is the SOAP encoding, which may be locally modified or used to obtain alternative encodings, which may be locally modified, but it may be set to an encoding that is shared, or it may be set to null, in which case all non-literal header blocks and parameters must specify an encoding.
attribute
nsISOAPEncoding
encoding
A convenience attribute to obtain the DOM element representing the SOAP envelope from the document. DOM methods may be used to access, add, or modify attributes of the envelope. If the message attribute is null or is not a document containing a root soap envelope element, then this will be null.
readonly attribute
nsIDOMElement
envelope
A convenience attribute to obtain the DOM element representing the SOAP header from the envelope. DOM methods may be used to access, add, or modify attributes or elements of the header. If the envelope attribute is null or does not contain a SOAP header element type, then this will be null.
readonly attribute
nsIDOMElement
header
The document which captures the message, if any. A simple sending application passes parameters to the method encodeSOAPParameters, which calls SOAP encoders to construct this document along with all contained elements. But an application may create and set the message directly instead of invoking encodeSOAPParameters to use encoders or access and manipulate the message after it has been constructed by encodeSOAPParameters. If the message has not been set, invoking a call will fail. A message reciever may also use this accessor to get the document to avoid using decoders.
attribute
nsIDOMDocument
message
The name of the method being invoked. The methodName is set during encoding as the tagname of the single child of body of RPC-style messages. When there is no encoded message this will be null. The value of this attribute for document-style messages may be non-null but should be ignored. It is up to the application to know whether the message is RPC-style or document style because the SOAP specification makes it difficult to tell which way a message was encoded.
readonly attribute
AString
methodName
The target object on which the method is being invoked. This URI is set during encoding as the namespace to qualify the tagname of the single child of body of RPC-style messages. When there is no encoded message, this will be null. The value of this attribute for document-style messages may be non-null but should be ignored. It is up to the application to know whether the message is RPC-style or document style because the SOAP specification makes it difficult to tell which way a message was encoded.
readonly attribute
AString
targetObjectURI
A convenience attribute to obtain the SOAP version number, if it is known, from the envelope. If the message attribute is null or is not a document containing a root soap envelope element, then this will be VERSION_UNKNOWN.
readonly attribute
unsigned short
version
Methods
Encodes the specified parameters into this message, if this message type supports it. @param aMethodName The name of the method being invoked for rpc-style messages. For document-style messages, this must be null. @param aTargetObjectURI The name of the target object for rpc-style messages. For document-style messages, this must be null. @param aHeaderBlockCount Number of header blocks in array to be encoded. Must be 0 if header block array is null. @param aHeaderBlocks Array of header blocks to be encoded, which may be null if there are no header blocks. @param aParameterCount Number of parameters in array to be encoded. Must be 0 if parameter array is null. @param aParameters An array of parameters to be encoded, which may null if there are no parameters.

Gathers the header blocks of a message so that they can be accessed by a recipient. @param aCount Integer to receive the length of the list of header blocks. @return Array of header blocks found in the message.
void
getHeaderBlocks(out unsigned long aCount, [array, size_is(aCount), retval] out nsISOAPHeaderBlock aHeaderBlocks)
Gathers the parameters of a message so that they can be accessed by a recipient. @param aDocumentStyle If true, then the parameters are looked for treating the message as a document style message, otherwise it treated as an RPC-style message. @param aCount Integer to receive the length of the list of parameters. @return Array of parameters found in the message.
