In sample soap XML request message, I noticed that there are soap envelope tag

  • 0

In sample soap XML request message, I noticed that there are soap envelope tag as 

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Header>
...

Is it okay to remove these tags? For example,change the soap message as,

<soapenv:Envelope>
<Header>
...

Is this standard that all soap message must have?

Thanks.

    The soap message is required, the namespace may be used by the receiving end to determine the version of the soap message. The namespace you are using, from what I understand, says this message follows Soap 1.1 standards. If you try to use Soap 1.2 features in that message, the server will most likely get confused.

    Section 4.1.2 of the soap 1.1 standard

    SOAP does not define a traditional versioning model based on major and
    minor version numbers. A SOAP message MUST have an Envelope element
    associated with the “http://schemas.xmlsoap.org/soap/envelope/”
    namespace. If a message is received by a SOAP application in which the
    SOAP Envelope element is associated with a different namespace, the
    application MUST treat this as a version error and discard the
    message. If the message is received through a request/response
    protocol such as HTTP, the application MUST respond with a SOAP
    VersionMismatch faultcode message (see section 4.4) using the SOAP
    “http://schemas.xmlsoap.org/soap/envelope/” namespace.
