Watson1978 · 2024-07-19T09:28:06Z

This patch will add the test cases to verify that it raises an exception properly when parsing malformed entity declaration.

Could you use syntax part name such as GeneralEntityDeclration instead of GarbgedValue for test case name? We want to organize tests based of syntax part not invalid type to avoid missing case.

Suggested change

Could you also add generic entity declaration definition (and related definitions in this test case) as a comment for easy to understand?

For example, "valid-name" and invalid-external-id.

@kou Thank you for your review. I fixed the tests.

not-ndata or something is better than invalid-external-entity because it should be NDATA.

REXML::Document.new('<!DOCTYPE root [<!ENTITY % valid-name "valid-entity-value" NDATA valid-ndata-value > ]>')

BTW, should we use the ExternalID NDataDecl? part instead of the EntityValue part in EntityDef ::= EntityValue | ExternalID NDataDecl?)? If we want to use the EntityValue part, we should use "garbage" or something instead of ndata_declaration because all contents (including NDataDecl) are invalid after the EntityValue.

Make sence.
We should make sure to check that any unnecessary NDataDecl after EntityValue will raise an exception.

Thank you for adding test cases which follows XML's entity declarations.

https://www.w3.org/TR/2006/REC-xml11-20060816/#sec-entity-decl

Should we test PEReference or Reference which are included in EntityValue although those test cases might be out of scope ?
And also, how about adding the following test cases?

Using single quotes
Using mixed quotes (' dummy " or " dummy ')
Removing necessary spaces

Could you move this to TestEntityDefinition and use test_entity_value_and_notation_data_declaration?

This test case is for EntityValue not EntityDef.

Watson1978 · 2024-07-23T05:43:08Z

* Using single quotes

I want to add invalid cases in this PR. I think this case is valid test.
So, I didn't add this case.

* Using mixed quotes (`' dummy "` or `" dummy '`)

* Removing necessary spaces

I added at
