This rule allows the definition of custom rules using XPath expressions.
Issues are created depending on the return value of the XPath expression. If the XPath expression returns:
- a single or list of AST nodes, then a line issue with the given message is created for each node
- a boolean, then a file issue with the given message is created only if the boolean is true
- anything else, no issue is created
On the following code, the XPath expression //IDENTIFIER[string-length(@tokenValue) >= 10] generates a violation on the identifier
"aaaaaaaaaa":
DECLARE
aaaaaaaaaa NUMBER := 10; /* Non-Compliant, this identifier is 10 characters long */
aaaaaaaaa NUMBER := 9; /* Compliant, this one is only 9 */
BEGIN
NULL;
END;
