base-uri throws Error XQST0046 when I trying to apply base-uri to nodes

[donaldjohn]

My XQuery like this:
for $cit in /*:CitedReferenceCIT[@status = 'D'] where contains($cit/@file, "#") return string-join(base-uri($cit/@file))
When I run this query, I got the error prompt like this:
Error: Stopped at C:/Users/Administrator/Desktop/XQuery/233Update.xq, 3/28: [XQST0046] URI '/STD_KR_CIT_ZIP/20160927/20070102/20070102-1-001.ZIP/1/KR202007000003512KR00200700003560ACITKO20070102KR00#/KR202007000003512KR00200700003560ACITKO20070102KR00#.XML' is invalid.
It seems related to the '#', but this is what it is in the file path, there is no way to overcome this, Can anyone tell me how to overcome this?

Various characters (#, ^) are no legal URI characters. They would need to be encoded before they are stored in a database. As this introduces backword compatibility issues (…after the change, a file #.xml will need to be adressed by db:open('db', '%23.xml'), it has not been fixed so far.

A hack to overcome this could be to create your uri manually (e.g. via 'iri-to-uri(file:///' || $your-root-directory || $cit/@file)). Maybe you don’t even need to encode the path to a base URI, but this depends on what you what you do with it. And I assume that your usage of string-join is obsolete?

As this is a duplicate of #1172, I’ll be closing this issue. For general questions and unconfirmed bugs, please write to our basex-talk mailing list.

I want to get the document path of the node, I checked #1172 and found that db:path is more suitable
