Forum OpenACS Q&A: Commenting xql files?

Request notifications

Posted by Randy O'Meara on
I've looked around the source somewhat and don't see an example of comments contained in a .xql file. Is it possible to place comments in .xql files? How?

You could put comments in the SQL of a query with regular SQL comments: -- This is a comment.

But as far as an XML comment tag, I don't know of one.

Hello Roberto,

If the XQL file is valid XML 1.0, the comment could use the valid tag.

Just my 2 cents

I agree that we need comments in the XQL files, but please not in the SQL clause.

It works with tDOM, as long as you do not put a comment within a <querytext> tag.

Good info. I had tried this type of comment outside any "queryset" element, both before and after "xml version" element and the system complained:

  Error: OH OH, error, first node is comment and not 'queryset'

and refused to load the xql file. I didn't take it further before I posted this question.

However, after reading the resonses, I delved a little deeper. And, as Andrei and Bruno indicate above, the standard comment mechanism does work within the "queryset" element but ouside of the "querytext" element.

Is there an emacs expert (Bart?) that can tell me how to make these xml comments stand out in font-lock? I'm using the emacs settings defined by Bart in This article.

BTW, this applies to the 4.6 CVS tip of a coupel weeks ago and AOLserver with nsxml (not checked with tDom), if that makes any difference.
