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
Here is an example of an XPath expression to log an issue on each GO TO statement:
//gotoStatement
