Should we use uri-collection() for determine whether binary resources exist or not

[joeytakeda]

Unlike collection(), the function uri-collection() makes no attempt at parsing the document it finds in its collection (since Saxon 9.7); it simply just lists all of the URI's in the collection: https://www.saxonica.com/html/documentation/sourcedocs/collections.html.

So we could list ALL URIs in the project from the outset and then just resolve paths to see whether or not the thing exists.

Sounds like a great idea -- but what do you mean by "just resolve paths"?

[joeytakeda]

I meant that, during our path resolution steps, if we have something like:

graphic:myImage.jpeg

And we know that "graphic" resolves to "../../graphics/"

Then we can resolve ../../graphics/myImage.jpeg into a full URI:

/path/to/my/project/graphics/myImage.jpeg

and then simple see if that path exists in the uri-collection() sequence.

Got it, thanks!
