[jira] Created: (MUSE-290) Issue in XmlUtils.setNamespaceAttribute() method

Issue in XmlUtils.setNamespaceAttribute() method
------------------------------------------------

                 Key: MUSE-290
                 URL: https://issues.apache.org/jira/browse/MUSE-290
             Project: Muse
          Issue Type: Bug
          Components: Utilities - General, QName, and XML
    Affects Versions: 2.2.0
         Environment: any
            Reporter: Eitan Plotnik
            Assignee: Dan Jemiolo
            Priority: Minor


The method appends a colon and prefix values to the namespace if the specified prefix isn't null.
It should do the same if the specified prefix is an empty string.
E.g. modify line 1854 from "if (prefix != null)" to "if (prefix != null && !"".equals(prefix))"

Hi Eitan,

The prefix cannot be null, so an empty string is used to indicate "no
prefix".  It doesn't make sense to prepend a colon to the namespace if
there is no prefix.

Otherwise, schema parsers may throw errors that a colon is found but no
prefix is set, because they don't know the intent of why the colon was
specified (i.e. is the prefix missing, or should it be empty string?).

This link provides some insight into the trickery of default/empty/null namespaces:

Hi Vinh,

The current situation _is_ that a colon is appended to the namespace even if the prefix is an empty string, resulting in an invalid namespace (e.g. "xmlns:") which can't be read by parsers.
I suggested to fix the condition to test for empty strings in addition to null prefixes.

Eitan.
