Cannot open file from URL

[GiorgioAresu]

Hi,
I'm using a stylesheet which loads an external file like this:

<xsl:variable name="secondaryFileXml" select="document($languageXPath)"/>

where languageXPath contains a relative path and all works, everyone is happy.

The issue is I'm developing an API which transforms the XSL server-side, and I'd like that path to be an URL instead of a filesystem path (or at least a path relative to the stylesheet itself), but if I change $languageXPath with something else, let's say http://localhost:3000/public/[...]/it.xml I get:

I/O warning : failed to load external entity "http://localhost:3000/public/[...]/it.xml"

It goes without saying that opening that url in a browser works just fine, as well as letting a browser perform the transformation.

I took a look at the underlying libxmljs and it seems that the HTTP part is optional, so enabling it would probably work.

Is there anything we could do?

Thanks

Can anyone help please?
