raptor_new_namespace_from_uri ()

raptor_namespace *
raptor_new_namespace_from_uri (raptor_namespace_stack *nstack,
                               const char *prefix,

                               int depth);

Constructor - create a new namespace from a prefix and URI object.

This declares but does not enable the namespace declaration (or 'start' it) Use raptor_namespaces_start_namespace() to make the namespace enabled and in scope for binding prefixes.

Alternatively use raptor_namespaces_start_namespace_full() can construct and enable a namespace in one call.

raptor_new_namespaces ()

raptor_namespace_stack *
raptor_new_namespaces (raptor_world *world,
                       int defaults);

Constructor - create a new raptor_namespace_stack.

See raptor_namespaces_init() for the values of defaults .

raptor_namespaces_init ()

int
raptor_namespaces_init (raptor_world *world,
                        raptor_namespace_stack *nstack,
                        int defaults);

Initialise an existing namespaces stack object

This sets up the stack optionally with some common RDF namespaces.

defaults can be 0 for none, 1 for just XML, 2 for RDF, RDFS, OWL and XSD (RDQL uses this) or 3+ undefined.

raptor_namespaces_clear ()

void
raptor_namespaces_clear (raptor_namespace_stack *nstack);

Empty a namespace stack of namespaces and any other resources.

raptor_free_namespaces ()

void
raptor_free_namespaces (raptor_namespace_stack *nstack);

Destructor - destroy a namespace stack

raptor_namespaces_start_namespace ()

void
raptor_namespaces_start_namespace (raptor_namespace_stack *nstack,
                                   raptor_namespace *nspace);

Start a namespace on a stack of namespaces.

raptor_namespaces_start_namespace_full ()

int
raptor_namespaces_start_namespace_full
                               (raptor_namespace_stack *nstack,
                                const char *prefix,
                                const unsigned char *ns_uri_string,
                                int depth);

Create a new namespace and start it on a stack of namespaces.

See raptor_new_namespace() for the meanings of prefix , ns_uri_string and depth for namespaces.

raptor_namespaces_end_for_depth ()

void
raptor_namespaces_end_for_depth (raptor_namespace_stack *nstack,
                                 int depth);

End all namespaces at the given depth in the namespace stack.

raptor_namespaces_get_default_namespace ()

raptor_namespace *
raptor_namespaces_get_default_namespace
                               (raptor_namespace_stack *nstack);

Get the current default namespace in-scope in a stack.

raptor_namespaces_find_namespace ()

raptor_namespace *
raptor_namespaces_find_namespace (raptor_namespace_stack *nstack,
                                  const char *prefix,
                                  int prefix_length);

Find a namespace in a namespace stack by prefix.

Note that this uses the length so that the prefix may be a prefix (sic) of a longer string. If prefix is NULL, the default namespace will be returned if present, prefix_length length is ignored in this case.

raptor_namespaces_find_namespace_by_uri ()

raptor_namespace *
raptor_namespaces_find_namespace_by_uri
                               (raptor_namespace_stack *nstack,
                                raptor_uri *ns_uri);

Find a namespace in a namespace stack by namespace URI.

raptor_namespaces_namespace_in_scope ()

int
raptor_namespaces_namespace_in_scope (raptor_namespace_stack *nstack,
                                      const raptor_namespace *nspace);

Test if a given namespace is in-scope in the namespace stack.

raptor_new_namespace ()

raptor_namespace *
raptor_new_namespace (raptor_namespace_stack *nstack,
                      const char *prefix,
                      const unsigned char *ns_uri_string,
                      int depth);

Constructor - create a new namespace from a prefix and URI string with a depth scope.

This declares but does not enable the namespace declaration (or 'start' it) Use raptor_namespaces_start_namespace() to make the namespace enabled and in scope for binding prefixes.

Alternatively use raptor_namespaces_start_namespace_full() can construct and enable a namespace in one call.

The depth is a way to use the stack of namespaces for providing scoped namespaces where inner scope namespaces override outer scope namespaces. This is primarily for RDF/XML and XML syntaxes that have hierarchical elements. The main use of this is raptor_namespaces_end_for_depth() to disable ('end') all namespaces at a given depth. Otherwise set this to 0.

raptor_free_namespace ()

void
raptor_free_namespace (raptor_namespace *ns);

Destructor - destroy a namespace.

raptor_namespace_get_uri ()

raptor_uri *
raptor_namespace_get_uri (const raptor_namespace *ns);

Get the namespace URI.

raptor_namespace_get_prefix ()

const unsigned char *
raptor_namespace_get_prefix (const raptor_namespace *ns);

Get the namespace prefix.

raptor_namespace_get_counted_prefix ()

const unsigned char *
raptor_namespace_get_counted_prefix (const raptor_namespace *ns,
                                     size_t *length_p);

Get the namespace prefix and length.

raptor_namespace_write ()

int
raptor_namespace_write (raptor_namespace *ns,
                        raptor_iostream *iostr);

Write a formatted namespace to an iostream

raptor_namespace_stack_start_namespace ()

int
raptor_namespace_stack_start_namespace
                               (raptor_namespace_stack *nstack,
                                raptor_namespace *ns,
                                int new_depth);

Copy an existing namespace to a namespace stack with a new depth and start it.

The depth is a way to use the stack of namespaces for providing scoped namespaces where inner scope namespaces override outer scope namespaces. This is primarily for RDF/XML and XML syntaxes that have hierarchical elements. The main use of this is raptor_namespaces_end_for_depth() to disable ('end') all namespaces at a given depth. If depths are not being needed it is unlikely this call is ever needed to copy an existing namespace at a new depth.

raptor_namespace_format_as_xml ()

unsigned char *
raptor_namespace_format_as_xml (const raptor_namespace *ns,
                                size_t *length_p);

Format a namespace in an XML style into a newly allocated string.

Generates a string of the form xmlns:prefix="uri", xmlns="uri", xmlns:prefix="" or xmlns="" depending on the namespace's prefix or URI. Double quotes are always used.

If length_p is not NULL, the length of the string is stored in the address it points to.

raptor_xml_namespace_string_parse ()

int
raptor_xml_namespace_string_parse (const char *string,
                                   unsigned char **prefix,
                                   unsigned char **uri_string);

Parse a string containing an XML style namespace declaration into a namespace prefix and URI pair.

The string is of the form xmlns:prefix="uri", xmlns="uri", xmlns:prefix="" or xmlns="". The quotes can be single or double quotes.

Two values are returned from this function into *prefix and *uri_string . Either but not both may be NULL.
