Hello,
We are using the final release BaseX 11.0 and Xerces 2.12.2 XSD 1.1 engine.
There is a need to validate XML file and check XML file name for naming convention. Unfortunately, the assert with the base-uri(.) function is not working as expected in the assert expression.
Observations: The XPath expression on the XML file emits, as expected, the following: o XPath: base-uri(.) o Results: file:/C:/Users/i300179/Downloads/ATF_NESS/base-uri/input.xml
The XPath expression on the XML file emits, as expected, the following: o XPath: tokenize(base-uri(.),"/")[last()] o Results: input.xml
I tried multiple expressions around base-uri(.) function. None of them worked. You will find all my attempts in the XSD file.
The test case XQuery/XML/XSD is below.
We are using Xerces, but the following Saxon excerpt could be pointing to the root cause of the problem.
For the reference: https://www.saxonica.com/html/documentation10/functions/fn/base-uri.html "It is possible for the base URI of a document to be absent (unknown). This happens when the document is supplied to Saxon with no location information: for example when the node is represented using a tree model such as DOM that has no base URI information; or when a Source is supplied for which getSystemId() returns null. The most common example of this is a Source created using new StreamSource(new FileInputStream("input.xml")). The problem can be fixed by using the second argument of the StreamSource constructor, or by using the constructor that expects a File rather than an InputStream."
