Description

The Python program using SaxonC HE 12.5

from saxonche import *

from pathlib import Path

xquery1 = '"Static base uri : " || static-base-uri()'

with PySaxonProcessor() as saxon_proc:
    print(saxon_proc.version)

    xpathProcessor = saxon_proc.new_xpath_processor()

    workingDirPath = str(Path.cwd().absolute())

    print(workingDirPath)

    xpathProcessor.set_cwd(workingDirPath)

    result = xpathProcessor.evaluate(xquery1)

    print(result)

prints out static base URI as empty although I use xpathProcessor.set_cwd(workingDirPath) to attempt to set it.

Output:

I also see the empty result from string provided XPath in the C++ API e.g. code like

	std::cout << "Testing static-base-uri function from XPathProcessor" << std::endl;

	XPathProcessor* xpathProcessor = saxonProc->newXPathProcessor();

	xpathProcessor->setcwd(std::filesystem::current_path().string().c_str());

	try {

		XdmItem* item = xpathProcessor->evaluateSingle("'static base URI in XPath is: ' || static-base-uri()");

		std::cout << item->getStringValue() << std::endl;

	}
	catch (SaxonApiException& exception) {
		std::cout << "Exception: " << exception.what() << std::endl;
	}

outputs nothing for the static base URI:

This issue is similar to #6605 - set the base uri on the XPath compiler. Fixed and available for the next maintenance release.
