Attachments and Rules

After identifying the appropriate group to which an XML file belongs, the system takes each message in the file and applies the appropriate XSL transformation to the message to produce a record on the upload staging table.

To process the messages in a file, the system needs to know how to identify each message in a file containing multiple messages. A file may use the same root element for each message or different root elements for different types of messages. For each XAI group, you must indicate the root element(s) that identifies a message by defining one or more attachments. Each attachment defines a root element, which tells the system when a new message begins.

Once the system has identified each separate message in the file, it must determine the correct XSL transformation script to apply. Once again the system uses an XPath and XPath value to identify the correct XSL to apply. For each XAI group, you define one XAI rule for every possible type of message you may receive in the file. Each XAI rule defines an XPath, XPath value and XSL transformation script.

Note you may assign a priority to each of your rules. The rules for more common messages may be assigned a higher priority. This enhances performance by ensuring that rules for more common messages are processed before rules for less common messages.
