rdflib.plugins.parsers.notation3.base()[source]¶

The base URI for this process - the Web equiv of cwd

Relative or absolute unix-standard filenames parsed relative to this yield the URI of the file. If we had a reliable way of getting a computer name, we should put it in the hostname just to prevent ambiguity

Use URL encoding to return an ASCII string corresponding to the given UTF8 string

>>> hexify("http://example/a b")
b'http://example/a%20b'

rdflib.plugins.parsers.notation3.join(here, there)[source]¶

join an absolute URI and URI reference (non-ascii characters are supported/doctested; haven’t checked the details of the IRI spec though)

here is assumed to be absolute. there is URI reference.

>>> join('http://example/x/y/z', '../abc')
'http://example/x/abc'

Raise ValueError if there uses relative path syntax but here has no hierarchical path.

>>> join('mid:foo@example', '../foo') 
Traceback (most recent call last):
    raise ValueError(here)
ValueError: Base <mid:foo@example> has no slash
after colon - with relative '../foo'.

>>> join('http://example/x/y/z', '')
'http://example/x/y/z'

>>> join('mid:foo@example', '#foo')
'mid:foo@example#foo'

We grok IRIs

>>> len(u'Andr\xe9')
5

>>> join('http://example.org/', u'#Andr\xe9')
u'http://example.org/#Andr\xe9'

rdflib.plugins.parsers.notation3.runNamespace()[source]¶: Returns a URI suitable as a namespace for run-local objects

('abcdef', '')

>>> # is the name of entity E10009 "Arco Publications"?
>>> #   (in graph http://bibliographica.org/entity/E10009)

__module__ = 'rdflib.plugins.parsers.rdfxml'¶

absolutize(uri)[source]¶

add_reified(sid, spo)[source]¶

characters(content)[source]¶

Receive notification of character data.

The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity so that the Locator provides useful information.

convert(name, qname, attrs)[source]¶

property current¶

document_element_start(name, qname, attrs)[source]¶

endElementNS(name, qname)[source]¶

Signals the end of an element in namespace mode.

The name parameter contains the name of the element type, just as with the startElementNS event.

endPrefixMapping(prefix)[source]¶

End the scope of a prefix-URI mapping.

See startPrefixMapping for details. This event will always occur after the corresponding endElement event, but the order of endPrefixMapping events is not otherwise guaranteed.

error(message)[source]¶

get_current()[source]¶

get_next()[source]¶

get_parent()[source]¶

ignorableWhitespace(content)[source]¶

Receive notification of ignorable whitespace in element content.

Validating Parsers must use this method to report each chunk of ignorable whitespace (see the W3C XML 1.0 recommendation, section 2.10): non-validating parsers may also use this method if they are capable of parsing and using content models.

SAX parsers may return all contiguous whitespace in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.

list_node_element_end(name, qname)[source]¶

literal_element_char(data)[source]¶

literal_element_end(name, qname)[source]¶

literal_element_start(name, qname, attrs)[source]¶

property next¶

node_element_end(name, qname)[source]¶

node_element_start(name, qname, attrs)[source]¶

property parent¶

processingInstruction(target, data)[source]¶

Receive notification of a processing instruction.

The Parser will invoke this method once for each processing instruction found: note that processing instructions may occur before or after the main document element.

A SAX parser should never report an XML declaration (XML 1.0, section 2.8) or a text declaration (XML 1.0, section 4.3.1) using this method.

property_element_char(data)[source]¶

property_element_end(name, qname)[source]¶

property_element_start(name, qname, attrs)[source]¶

reset()[source]¶

setDocumentLocator(locator)[source]¶

Called by the parser to give the application a locator for locating the origin of document events.

SAX parsers are strongly encouraged (though not absolutely required) to supply a locator: if it does so, it must supply the locator to the application by invoking this method before invoking any of the other methods in the DocumentHandler interface.

The locator allows the application to determine the end position of any document-related event, even if the parser is not reporting an error. Typically, the application will use this information for reporting its own errors (such as character content that does not match an application’s business rules). The information returned by the locator is probably not sufficient for use with a search engine.

Note that the locator will return correct information only during the invocation of the events in this interface. The application should not attempt to use it at any other time.

startDocument()[source]¶

Receive notification of the beginning of a document.

The SAX parser will invoke this method only once, before any other methods in this interface or in DTDHandler (except for setDocumentLocator).

startElementNS(name, qname, attrs)[source]¶

Signals the start of an element in namespace mode.

The name parameter contains the name of the element type as a (uri, localname) tuple, the qname parameter the raw XML 1.0 name used in the source document, and the attrs parameter holds an instance of the Attributes class containing the attributes of the element.

The uri part of the name tuple is None for elements which have no namespace.

startPrefixMapping(prefix, namespace)[source]¶

Begin the scope of a prefix-URI Namespace mapping.

The information from this event is not necessary for normal Namespace processing: the SAX XML reader will automatically replace prefixes for element and attribute names when the http://xml.org/sax/features/namespaces feature is true (the default).

There are cases, however, when applications need to use prefixes in character data or in attribute values, where they cannot safely be expanded automatically; the start/endPrefixMapping event supplies the information to the application to expand prefixes in those contexts itself, if necessary.

Note that start/endPrefixMapping events are not guaranteed to be properly nested relative to each-other: all startPrefixMapping events will occur before the corresponding startElement event, and all endPrefixMapping events will occur after the corresponding endElement event, but their order is not guaranteed.

class rdflib.plugins.parsers.rdfxml.RDFXMLParser[source]¶
