Re: [Exist-open] %test:assertXPath help

Hi Bernie, I've just had a look at the XQSuite source where %assertXPath annotations are processed ( https://github.com/eXist-db/exist/blob/develop/exist-core/src/main/resources/org/exist/xquery/lib/xqsuite/xqsuite.xql#L944-L992). It appears to me that XQSuite dynamically constructs namespace declarations based on the in-scope namespaces in the return value of the function. So if your function's return value contained an HTML element with namespace prefix bindings, like: <html:html xmlns:html="http://www.w3.org/1999/xhtml"> ... XQSuite would dynamically create the following namespace declaration: declare namespace xhtml='http://www.w3.org/1999/xhtml'; ... which would be prepended to your %assertXPath annotation and evaluated. Since your function's return value doesn't associate <html> with any namespace prefix - only a namespace URI - then you should construct your %assertXPath annotations with the expectation that elements have a default namespace of "http://www.w3.org/1999/xhtml". Thus I would suggest that you try modifying your %assertXPath annotations to be: %test:assertXPath("$result//html") %test:assertXPath("$result//html/head[title = 'Bad Request']") %test:assertXPath("$result/html/body/p[@class = 'ErrorMessage']") I haven't tested this myself, so if you give this a try, could you let us know the result? If we confirm that my hunch is correct, then we could supply some additional hints in the documentation for this annotation at https://exist-db.org/exist/apps/doc/xqsuite#annotations. Thanks!
