XmlQueryContext::getNamespace

APIRef

#include <DbXml.hpp>

std::string XmlQueryContext::getNamespace(const std::string &prefix);

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_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.
