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 <code>//IDENTIFIER[string-length(@tokenValue) >= 10]</code> 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;
