Pros:
- Allows executing multiple commands in one batch
Cons (at the time of implementation):
- The response document does not contain the original request: log analysis and analysis on the side of third-party systems is difficult

Example:

Request

Code Block

language	xml

<?xml version="1.0" encoding="utf-8"?>
<RK7Query>
	<RK7Command CMD="GetSystemInfo"/>
	<RK7Command CMD="GetRefData" RefName="EventList"/>
</RK7Query>

Response

Code Block

language	xml

<?xml version="1.0" encoding="utf-8"?>
<RK7QueryResult ServerVersion="7.6.5.92" XmlVersion="246" NetName="OA-01-REPS-000" Status="Ok" Processed="2">

Development of RK7Command in order to save information about the original request in the response, in the SourceCommand tag
Pros:
- Allows getting the source text of the request in the resulting XML, which in its turn
  - Simplifies log analysis — a request and a response in one place
  - Simplifies parsing on the side of the external system
Cons (at the time of implementation)
- Increasing traffic. Possible solutions:
  - HTTP: Usage of GZIP
  - RK7XML.DLL compresses the data itself
- Increasing XML parsing time. Possible solutions:
  - To investigate increase: if it is critical, DO NOT use this option
- In the case of not quite correct XML parsing code, code adaptation will be required:
  - For example, if nodes were selected by numbers/lists of child objects

Example:

Request

Code Block

language	xml

<?xml version="1.0" encoding="utf-8"?>
<RK7Query>
	<RK7Command2 CMD="GetSystemInfo"/>
	<RK7Command2 CMD="GetRefData" RefName="EventList"/>
