Saxon-HE 9.7: "no base URI is available" error, when trying to run query string from bash

Question

According to Saxon's documentation,

java net.sf.saxon.Query -qs:doc('a.xml')//p1 selects elements within the file a.xml in the current directory.

I'm trying to do just that from a bash script:

java net.sf.saxon.Query -qs:doc"('myFile.xml')"/rootElt/@myAtt

However, I get the following error: XTDE1162: Relative URI passed to document() function (myFile.xml); but no base URI is available

According to the docs, this shouldn't happen:

The static base URI (used when calling the doc() function) is the current directory.

I have tried using an absolute URI, but surprisingly, I still get the exact same error message.

May I use some help?

Answer 1

Solved. When passing a query string, there is no base URI (no resource in the file system containing the query), so pass one with resolve-uri() as its second argument:

-qs:"doc(resolve-uri('myFile.xml', 'file:$PWD/'))/rootElt/@myAtt/xs:string(.)"

It seems to me that Saxonica should update the documentation for command line option -qs with this detail (it may take a while to figure this out on your own).
