Transaction ID determination
The TrxID of an XML message is the name of the root element. For messages with no namespace that is associated with the root element, the TrxID is the root element. For messages with a namespace, the TrxID is one of two possibilities:
- The namespace prefix followed by the element name.
- The namespace URL followed by the element name.
Which one is used depends on whether the message definition was generated from a DTD or a schema:
- If it is based on a DTD, then the TrxID is the namespace prefix followed by the element name.
- If the OCM was created from a schema, then the TrxID is the namespace URL followed by the element name.
In the definition of a protocol thread, there is a
DATAFORMAT
key in the Netconfig file that contains a
TYPE
key.
XML TrxID determination uses xml
as the value for this key.
XML (Namespace) TrxID determination uses xml_ns
as the value for this
key. This value uses the namespace URL instead of the namespace prefix.
Specify the correct value based on the message formats. This is configured on the Network Configurator’s property panel.
Examples:
- The root element is prefixed associating it
with a namespace:
<cis:foo xmlns:cis=’http://www.example.com/test’>
- TrxID for
xml
:cis:foo
- TrxID for
xml_ns
:http://www.example.com/test:foo
- TrxID for
- The root element is not prefixed, but belongs
to a default namespace:
<foo xmlns=’http://www.example.com/test’>
- TrxID for
xml
:foo
- TrxID for
xml_ns
:http://www.example.com/test:foo
- TrxID for
- The root element does not belong to a
namespace:
<foo>
- TrxID for
xml
:foo
- TrxID for
xml_ns
:foo
- TrxID for
