Documents with an Internal Subset DOCTYPE had stopped trying to bind

[zwaldowski]

My organization has documents like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE root [
    <!ENTITY foo "Bar">
]>

I'm trying to bind these documents using fileAssociations, but lsp4xml stops trying to bind at the DOCTYPE. It should continue looking for xsi:schemaLocation and in fileAssociations when the DOCTYPE lacks a DTD reference.

@zwaldowski could you please share a little vscode project with cases that you are describing please and give us trouble that you have (completion that you are waiting). Thanks!

See here. See the screenshots in the gist's comments.

I was having trouble getting the fileAssociations to bind correctly, so it's not a full vscode project; that's not the issue, though (that's my own inexperience 🙂). So it's just the single article.xml demonstrating the issue.

Thank's @zwaldowski for your feedback. I tested with your article.xml and I have the same issue but WTP XML Editor from Eclipse display the same errors. I'm not sure that we can mix internal DTD and XML Schema like this?

[zwaldowski]

I'm not familiar with WTP XML Editor. When we use Jing to render these documents, we bind a RelaxNG schema to it and it handles the entities fine. We've done this for ~15 years. Can you help me understand why this shouldn't work another way, perhaps?

[angelozerr]

It's a limitation of Xerces. But I found a topic about this problem https://www.oxygenxml.com/forum/topic12812.html#p36904 and Oxygen fixes the problem. The idea is to not validate XML with DTD (DOCTYPE) if DOCTYPE doesn't define <!ELEMENT or doesn't define PUBLIC, SYSTEM path.

I will try to follow this rule. I give you feedback if I can manage that.

Amazing work, thanks!

Glad it works for you @zwaldowski .Many thanks for your feedback.
