Deprecated version

This document refers to a deprecated version of the RQL programming language.

Please go here for documentation related to the latest supported version.

TRY_READ_XML behaves similarly to READ_XML but in case of connection or other problems returns null instead of failing with a runtime error after retries are exhausted.

encoding := "utf-8",
cache := <default interval>,
retries := <default int>, retry_interval := <default interval>)
