Hi all, I'm working with BDS 2006 Upg1, XPProf SP2, P4 1GBRAM. I'm building a xml doc, like others I've do, but with this doc I have a problem. In the DocumentElement Node, I put the xmlns attrib. ok no problem. but when I insert a new child to the DocumentElement the xmlns attrib is also created in the new node, but empty. How i must do to not create this attrib in the childnodes? My code: ---------------------------------------------------------- xmlDoc := TXMLDocument.Create(tblConfig.Owner); try xmlDoc.Version = '1.0'; xmlDoc.Active := TRUE; xmlElement := xmlDoc.CreateNode(xmlTC_FunctionCallRequest); xmlElement.SetAttribute('xmlns:xsd','myString'); xmlElement.SetAttribute('xmlns:xsi','myOtherString'); xmlElement.SetAttribute('xmlns','myAnotherString'); xmlDoc.DocumentElement := xmlElement; xmlNode := xmlElement.AddChild(xmlTC_TimeStamp); ... ---------------------------------------------------- The result: ----------------------------------------------------- <FunctionCallRequest xmlns:xsd="MyString" xmlns:xsi="MyOtherString" xmlns="MyAnotherString"> <Timestamp xmlns=""> ..... --------------------------------------------------- <Timestamp xmlns=""> is the problem. Must be <TimeStamp> Sorry for my English and thanks in advance. Back to top Remy Lebeau (TeamB) Guest Posted: Thu Feb 15, 2007 12:52 am    Post subject: Re: Self inherited of Node attribute.

That is because you are not actually assigning the namespace for the DocumentElement, so it is not available when child nodes are created. Do not use SetAttribute() to declare a namespace. You need to use the DeclareNamespace() method instead, ie: xmlElement.DeclareNamespace('xsd', 'myString'); xmlElement.DeclareNamespace('xsi', 'myOtherString'); xmlElement.DeclareNamespace('', 'myAnotherString'); Gambit Back to top Mia Gómez Guest Posted: Thu Feb 15, 2007 6:03 pm    Post subject: Re: Self inherited of Node attribute.

Still appears the xmlns="". Is like the namespace is inherited to all child nodes I create in the DocumentElement. Also I've tryied to put the namespace to the DocumentElement after I've added the child nodes, but the empty namespace appears too. Also I've tried modifying xmlDoc.Options, but doesn' work too. Any other idea? Many thanks.... Mia. Back to top Mia Gómez Guest Posted: Thu Feb 15, 2007 10:14 pm    Post subject: Re: Self inherited of Node attribute.

Any other idea? Many thanks.... Mia. Hi all again, I've solved this problem !! Once declared a namespace in the DocumentElement, all child nodes must be created in the same namespace. If the child nodes don't have nameSpace xmlns will be "". If the child nodes have a nameSpace diferent than the father node then the xmlns will be the child nameSpace (this last example may be incongruent, because i can't see why a child may be another nameSpace than the father node.) -BeginCode---------------------------------------- var xmlDoc: TXMLDocument; xmlElement, xmlNode, xmlNode1 : IXMLNode; strNameSpace: string; begin xmlDoc := TXMLDocument.Create(Self.Owner); try strNameSpace := 'myNameSpace'; xmlDoc.Active := TRUE; xmlDoc.Version := '1.0'; xmlElement := xmlDoc.CreateNode(xmlTC_FunctionCallRequest); xmlElement.DeclareNamespace('xsd', 'myXSD'); xmlElement.DeclareNamespace('xsi', 'myXSI'); xmlElement.DeclareNamespace('', strNameSpace); xmlDoc.DocumentElement := xmlElement; /// In the child node creation, we must put the same /// simple namespace than father node!!! xmlNode := xmlElement.AddChild('FirstNode',strNameSpace); xmlNode1 := xmlElement.AddChild('SecondNode',strNameSpace); ... -EndCode---------------------------------------- Thanks a lot Remy. You put me on the way to solve it.
