I figured out that the issue might relate to a file xsltSchema.js that in my install of the extension (~/.vscode/extensions/deltaxml.xslt-xpath-0.1.7/out/) actually is called xsltschema.hs. Thus, it has a different case and Linux obviously is case-sensitive for file path. I do not know if this is actually the issue but after renaming thins file I get a different error message than before. This time it is:

I think I leave it like that for now, not exactly knowing if I went into a completely wrong direction or not. Probably you have clearer idea about this.

[pgfearo]

Thank you for reporting both issues:

1. Extension activation error due to incorrect module name: xsltschema.js
2. getTextForToken function error: Illegal argument: character must be non-negative

V0.1.8 of this extension has now been published which fixes issue (1).
Regarding issue (2), I've added a check inside the function preventing a negative character number. The change means that if the character number negative a more helpful error should be logged, but the code should still run.

There is still an issue however for (2), the tokenizer should not produce negative character numbers so there is still a bug. Does this error occur when any XML/XSLT file is opened? If it's just for a specific file, could you please attach a file that reproduces the problem.

[Cutuchiqueno]

thx. for the quick feedback. I confirm that since v0.1.8 (1) is solved.

(2) now only happens when I create a new empty stylesheet. Stylesheets that have content already open and load the extension just fine.

(I know this does not belong in an issue report but still I wanted to say that I am so happy that this extension now exists, so thank you for the work!)

[pgfearo]

Ok, thanks for that info on (2) affecting just new empty stylesheets, I should be able to uncover the problem here.

Also, your encouraging comments are much appreciated.
