# XmlQueryContext.getNamespace

`

###

    import com.sleepycat.dbxml.*;

    public String getNamespace(String prefix)
        throws XmlException;

# Description

The XmlQueryContext.getNamespace method returns the namespace prefix to URI mapping for prefix.

If no mapping is found, the XmlQueryContext.getNamespace method will return Db.DB_NOTFOUND. Otherwise, the XmlQueryContext.getNamespace method throws an exception that encapsulates a non-zero error value on failure.

# Errors

The XmlQueryContext.getNamespace method may fail and throw an exception encapsulating a non-zero error for the following conditions:

EINVAL
  An invalid flag value or parameter was specified.

If the requested item could not be returned due to insufficient memory, the XmlQueryContext.getNamespace method will fail and throw a DbMemoryException exception.

The XmlQueryContext.getNamespace method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the XmlQueryContext.getNamespace method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
