Node Name Property

  • บทความ

As you use BizTalk Editor to insert nodes into the schema tree, some nodes are meant to be renamed and others are not. Essentially, you can and should rename Record nodes, Field Element nodes, and Field Attribute nodes. The names that you give to these nodes will become the names of the XML elements and attributes in the message that the schema defines.

In the schema tree, the nodes that you cannot rename are shown in the form of XML tags; that is, with the less than (<) and greater than (>) signs. For example, the Schema node, Choice Group nodes, Any Element nodes, and Any Attribute nodes are represented in the schema tree with the names <Schema>, <Choice>, <Any>, and <AnyAttribute>, respectively. The Node Name property for such nodes is read-only.

Within a given Record node, you cannot have two Field Attribute nodes with the same name. However, you can have more than one Field Element node or Record node with the same name as child nodes of the same Record node, as long as they all have the same data type (as specified by their Data Type property for Field Element nodes or their Data Structure Type for Record nodes).

When you give names to Record nodes, Field Element nodes, and Field Attribute nodes, use names that are descriptive of the role of that element or attribute within the message being defined by the schema. For example, FirstName is probably a good choice for the name of a Field Element node that will be used to store the first name of someone in an address structure. In an XML instance message where the first name James occurs, the corresponding element would look like the following.

    <FirstName>James</FirstName>

When you are renaming Record nodes, Field Element nodes, and Field Attribute nodes, you should be aware that not all characters are allowed in node names. For information about these disallowed characters, see Which Node Name Characters Get Encoded. Although BizTalk Editor allows you to use disallowed characters by encoding them, it is often simpler to avoid such characters altogether. For information about how disallowed characters are encoded, see How Node Name Characters Get Encoded.

In addition to the characters that are disallowed in node names, unless they are encoded in the XSD representation of the schema, you should not use C# reserved words as the names of any root nodes in the schema tree (unless you provide a valid RootNode TypeName property value) or as schema file names.
