Cannot load SEF stylesheet under NW.js
100%
Description
Using Saxon-JS 1.2.0, when trying to load a stylesheet in a NW.js app (v0.35.5) using Saxon-JS 1.2.0, the following is returned.
SaxonJS.js:17943 Uncaught XError: stylesheetLocation should be absolute by now
After digging into the code, the problem appears to come from the regex in the isAbsoluteURI function. Indeed, NW.js fetches the files from an 'chrome-extension://' URL.
Changing the regex to
/^(?:[a-z-]+:)?\/\//i
worked for me.

- Status changed from New to Resolved
- Fix Committed on JS Branch 1.0, Trunk added
The Uniform Resource Identifier (URI) spec (https://tools.ietf.org/html/rfc3986#section-3.1) says:
"Scheme names consist of a sequence of characters beginning with a letter and followed by any combination of letters, digits, plus ("+"), period ("."), or hyphen ("-"). Although schemes are case- insensitive, the canonical form is lowercase and documents that specify schemes must do so with lowercase letters. An implementation should accept uppercase letters as equivalent to lowercase in scheme names (e.g., allow "HTTP" as well as "http") for the sake of robustness but should only produce lowercase scheme names for consistency."
So for completeness, it looks like the regex should actually be /^(?:[A-Za-z][A-Za-z0-9+.-]+:)?\/\//i
Change committed on Saxon-JS 1.x and 2.0 branches.
