Does anyone know how to retrieve using OI the data type in an XML schema object or SOM using the getDeclaration method?

from this xml schema I want to retrieve the xs:string value using the getDeclaration method but cannot seem to do it.

I can't get this to work either. The VB example shows:

Set oDecl=oDoc.namespaces.getDeclaration(oDoc.documentElement)

MsgBox oDecl.namespaceURI

Which in Basic+ I tried:

oDoc=OleCreateInstance("Msxml2.DOMDocument.6.0")

oDoc-]ResolveExternals=True

oDoc-]async=False

oDoc-]ValidateOnParse=True

* load the XML and XSD into cache as in my previous example

oDocNS=oDoc-]namespaces

oDocElement=oDoc-]documentElement

oDecl=OleCallMethod(oDocNS,'getDeclaration',oDocElement)

is_ok=(OleStatus()=0)

msgbox=oDecl-]namespaceURI

is_ok returns 0

Perhaps one of the other VB to Basic+ wiz kids can tell us what I'm doing wrong.

The "Walk the SOM" example will work when converted to BASIC+. I don't know if that will help in what you're trying to do though.

Warren,

From what I can determine the only way the getDeclaration() method works is with a v4 DOM document - it fails with a v6.

This is from the example on MSDN:

pre.code {

 background-color: #E5E5E5;

 border: 1px solid #000000;

 width: 940px;

 padding: 5px;

 font-family: courier, verdana, arial, serif;

 margin: 0px 10px auto;

}

compile subroutine cp_test_another_xsd( void )

Thanks! At least I still have a few hairs left on my head.

MSFT removed XDR support in 6.0 but according to the version matrix getDeclaration is still supported. I ran across somewhere that there was a difference in how Namespaces were handled in 6.0 getDeclaration. Ha! Another undocumented feature I ran across on one forum is that in 6.0 you need to set the resolveExternals property to true for most of the schema functions to work in the first place unless using an inline schema.

4.0 has issues that it doesn't appear to support some schema features.
