xmldb api and namespace handling
I'am accessing BaseX 6.5.1 through the XMLDB API. There are some issues with namespace handling when storing resources. Let me clarify that with some examples. First example I want to store the following as a resource: String example = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>" + "<tag xmlns=\"http://example.org\">" + "</tag>"; This yields <tag xmlns="http://example.org"/> in the GUI. So this is OK. Second example I want to store the following as a resource and INTPARSE = false: String example = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>" + "<tns:tag xmlns:tns=\"http://example.org\">" + "</tns:tag>"; This yields the following exception: org.xmldb.api.base.XMLDBException: "null" (Line 1): The prefix "tns" for element "tns:tag" is not bound Third example I want to store the following as a resource and INTPARSE = true: String example = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>" + "<tns:tag xmlns:tns=\"http://example.org\">" + "</tns:tag>"; This yields <tns:tag xmlnstns="http://example.org"/> in the GUI. The colon is missing in ' xmlnstns' . So this is not OK. Are the second and third examples bugs or should I change some setting to get a proper handling of namespaces? Regards, Frans
Hi Frans, could you send me your java class, so i can have a look at it. -- Andreas Am 25.03.2011 um 00:01 schrieb frans@planet:

Third example
I want to store the following as a resource and INTPARSE = true:
String example = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>" + "<tns:tag xmlns:tns=\"http://example.org\">" + "</tns:tag>";

Hi Andreas, Thanks for your answer. I added some cases to your Test-class and I ran it against the newest release of BaseX (6.6). setContent and setContentAsDOM work fine. setContentAsSax works fine for <tag xmlns=\"http://example.org\"/>. For <tns:tag xmlns:tns=\"http://example.org\"/> setContentAsSax gives <tns:tag xmlnstns="http://example.org"/>. The colon is missing in xmlnstns.

Hi Frans, thanks for your further tests, we will have a look at that issue. Kind regards, Andreas Am 26.03.2011 um 17:53 schrieb frans@planet:
