- - ### Constructor Detail

    - #### PrefixResolverDefault

          public PrefixResolverDefault(Node xpathExpressionContext)

      Construct a PrefixResolverDefault object.
      Parameters:
        `xpathExpressionContext` - The context from which XPath expression prefixes will be resolved. Warning: This will not work correctly if xpathExpressionContext is an attribute node.

  - ### Method Detail

    - #### getNamespaceForPrefix

          public java.lang.String getNamespaceForPrefix(java.lang.String prefix)

      Given a namespace, get the corrisponding prefix. This assumes that the PrevixResolver hold's it's own namespace context, or is a namespace context itself.
      Specified by:
        `getNamespaceForPrefix` in interface `PrefixResolver`
      Parameters:
        `prefix` - Prefix to resolve.
      Returns:
        Namespace that prefix resolves to, or null if prefix is not bound.

    - #### getNamespaceForPrefix

          public java.lang.String getNamespaceForPrefix(java.lang.String prefix,
                                               Node namespaceContext)

      Given a namespace, get the corrisponding prefix. Warning: This will not work correctly if namespaceContext is an attribute node.
      Specified by:
        `getNamespaceForPrefix` in interface `PrefixResolver`
      Parameters:
        `prefix` - Prefix to resolve.
        `namespaceContext` - Node from which to start searching for a xmlns attribute that binds a prefix to a namespace.
      Returns:
        Namespace that prefix resolves to, or null if prefix is not bound.

    - #### getBaseIdentifier

          public java.lang.String getBaseIdentifier()

      Return the base identifier.
      Specified by:
        `getBaseIdentifier` in interface `PrefixResolver`
      Returns:
        null

    - #### handlesNullPrefixes

          public boolean handlesNullPrefixes()

      Specified by:
        `handlesNullPrefixes` in interface `PrefixResolver`

        `PrefixResolver.handlesNullPrefixes()`
