###

    import com.sleepycat.dbxml.*;

    public XmlValue getVariableValue(String name)
        throws XmlException;

# Description

The XmlQueryContext.getVariableValue method returns the value bound to the variable name.

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

# Errors

The XmlQueryContext.getVariableValue 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.

The XmlQueryContext.getVariableValue 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.getVariableValue method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
