I have an XML to XML mapping where I have to map Incoming XML attribute to Outgoing XML Element.

Incoming XML message is:
<?xml version = "1.0" encoding = "UTF-8"?>
<Input_Root_Tag>
<Child_Tag Identifier = "100" >
</Child_Tag>
</Input_Root_Tag>

Desired Output XML is:

<Output_Root_Tag>
<Out_Child_Tag>
<Out_Identifier>100</Out_Identifier>
</Out_Child_Tag>
</Output_Root_Tag>

1) I tried mapping :
SET OutputRoot.XML.Output_Root_Tag.Out_Child_Tag.Out_Identifier = InputRoot.XML.Input_Root_Tag.Child_Tag.(XML.Attribute)Identifier;

I get output
<Output_Root_Tag>
<Out_Child_Tag Out_Identifier = "100" \>
</Output_Root_Tag>


2) When I tried mapping:

SET OutputRoot.XML.Output_Root_Tag.Out_Child_Tag.(XML.Element)Out_Identifier = InputRoot.XML.Input_Root_Tag.Child_Tag.(XML.Attribute)Identifier;

I get output
<Output_Root_Tag>
<Out_Child_Tag>
<Out_Identifier/>
</Out_Child_Tag>
</Output_Root_Tag>

??
Can anyone tell me what is missing here??

Thanks in advance.

dev,
in my previous project I ran into similar problem, while mapping XML attribute with an Element. I think error may be due to the XML parsing and trying to assign Element to an attribute.
One of the way to solve it, make use of temp variable to assign the value. It may not be the best ... but works perfect.

Code:

declare X char;

set X = InputRoot.XML.Input_Root_Tag.Child_Tag.(XML.Attribute)Identifier ;
SET OutputRoot.XML.Output_Root_Tag.Out_Child_Tag.Out_Identifier = X;



best of luck

M
