Hi,
Using a recent 9.1 Beta on windows. I create an XML catalog at c:\tmp\mycatalog.xml
<catalog prefer="system" xmlns="urn:oasis:names:tc: entity:xmlns:xml:catalog"> <uri name="http://nowhere.com/doc" uri="file:///c:/tmp/doc.xml" /> </catalog>
Then in the GUI
fetch:xml("http://nowhere.com/doc", map{"catfile": "C:\tmp\mycatalog.xml"} )
It goes to nowhere, I was hoping to get back c:/tmp/doc.xml Should this work?
/Andy
Hi Andy,
Currently, XML catalog files will only be evaluated by the XML parser, which will be called after the addressed resource has been located and retrieved. In other words: The specified catalog file will be evaluated indeed, but only for URIs that occur within the specified XML document:
fetch:xml('file.xml', map { 'catfile': '/path/to/catalog.xml', 'dtd': true() })
file.xml: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "bla/blu.dtd"> <xml/>
catalog.xml: <catalog prefer="system" xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"> <rewriteSystem systemIdStartString="bla/" rewritePrefix="file:///path/to/dtd/" /> </catalog>
Hope this helps (a little), Christian

Ok, Thanks for the info it is what I guessed, but I note the "currently" :)
It would be good, long term, to look to matching the Saxon capabilties here [1], part of which (xslt) are covered by this issue [2].
And related: I wonder sometimes about a "xmldb:" uri scheme and a custom resolver that could be passed to 3rd party validation and transform libraries to allow them to access BaseX db resources. I seem to remember a number of issues on the list that could be related to the saving temp copies of db resources to the file system as seems to occur currently.
No doubt this would be a big task, if it is even possible :)

Thanks for your suggestions, Andy.
If you (or anyone else) have already worked with custom resolvers for 3rd party libraries in Java, feel free to pass me on examples. They might help us to provide support for xmldb: or basex: URI schemes.
