XInclude processing

XInclude processing is normally controlled via the Domlette reader APIs and is implemented within Domlette itself. This module just provides constants and classes to support XInclude processing.

XInclude is defined at http://www.w3.org/TR/xinclude

4XSLT initialization and XSLT pattern tools

These are the most common steps for using this XSLT engine:

1. Create an Ft.Xml.Xslt.Processor.Processor instance:

from Ft.Xml.Xslt import Processor processor = Processor.Processor()

2. Prepare Ft.Xml.InputSource instances (via their factory) for the source XML and for the stylesheet.

3. Call the Processor's appendStylesheet() method, passing it the stylesheet's InputSource.

4. Call the Processor's run() method, passing it the source document's InputSource.

You can call run() multiple times on different InputSources. When you're done, the processor's reset() method can be used to restore a clean slate (at which point you would have to append stylesheets to the processor again), but in most circumstances it is actually less expensive to just create a new Processor instance.

General-purpose utility class for generating XML (may eventually be expanded to produce more output types)

Sample usage:

from Ft.Xml import MarkupWriter writer = MarkupWriter(indent=u"yes") writer.startDocument() writer.startElement(u'xsa') writer.startElement(u'vendor') #Element with simple text (#PCDATA) content writer.simpleElement(u'name', content=u'Centigrade systems') #Note writer.text(content) still works writer.simpleElement(u'email', content=u"info@centigrade.bogus") writer.endElement(u'vendor') #Element with an attribute writer.startElement(u'product', attributes={u'id': u"100\u00B0"}) #Note writer.attribute(name, value, namespace=None) still works writer.simpleElement(u'name', content=u"100\u00B0 Server") #XML fragment writer.xmlFragment('<version>1.0</version><last-release>20030401</last-release>') #Empty element writer.simpleElement(u'changes') writer.endElement(u'product') writer.endElement(u'xsa') writer.endDocument()

Note on the difference between 4Suite writers and printers Writer - module that exposes a broad public API for building output bit by bit Printer - module that simply takes a DOM and creates output from it as a whole, within one API invokation

Convenience factory function for Markup writers (based on xsl:output in XSLT)

Create a simple tag with optional attributes and content. The complete element, start tag, optional text content, end tag, will all be generated by this one call. Must *not* be matched with an endElement call.

Note: all "strings" in these parameters must be unicode objects tagName - qualified name of the element namespace - optional namespace URI attributes - optional dictionary mapping name to unicode value the name can either be a unicode QName or a tuple of (QName, namespace URI) content - optional unicode object with the text body of the simple element extraNss - optional dictionary (defaults to an empty one) that creates additional namespace declarations that the user wants to place on the specific element. Each key is a ns prefix, and each value a ns name (URI). You do not need to use extraNss if you will be using a similar namespace parameter. In fact, most people will never need this parameter.

Create a start tag with optional attributes. Must eventually be matched with an endElement call

Note: all "strings" in these parameters must be unicode objects tagName - qualified name of the element (must be unicode) namespace - optional namespace URI attributes - optional dictionary mapping name to unicode value the name can either be a unicode QName or a tuple of (QName, namespace URI) extraNss - optional dictionary (defaults to an empty one) that creates additional namespace declarations that the user wants to place on the specific element. Each key is a ns prefix, and each value a ns name (URI). You do not need to use extraNss if you will be using a similar namespace parameter. In fact, most people will never need this parameter.

Incorporate a well-formed general entity into the output. fragment of fragment - string (must not be a Unicode object) to be incorporated verbatim into the output, after testing for wellp-formedness

- <attribute '__dict__' of 'MarkupWriter' objects>
- <attribute '__weakref__' of 'MarkupWriter' objects>

PyXML is required by some features of 4Suite (e.g., validating parsing, and 4XSLT's SaxWriter). This is a common function to test whether a correct version of PyXML is installed. It raises a SystemExit if the test result is negative, and returns None otherwise.

The feature argument is a string indicating which feature in 4Suite requires PyXML. It is output as part of the SystemExit message.

Convenience function for parsing XML. Use this function with a single argument, which must either be a string (not Unicode object), file-like object (stream), file path or URI.

Returns a Domlette node.

Only pass strings or streams to this function if the XML is self-contained XML (i.e. not requiring access to any other resource such as external entities or includes). If you get URI resolution errors, do not use this function: use the lower-level APIs instead. As an example, if you want such resolution to use the current working directory as a base, parse as follows for strings:

from Ft.Xml.Domlette import NonvalidatingReader from Ft.Lib import Uri

XML = "<!DOCTYPE a [ <!ENTITY b "b.xml"> ]><a>&b;</a>"

base = Uri.OsPathToUri('') #Turn CWD into a file: URL doc = NonvalidatingReader.parseString(XML, base) # during parsing, the replacement text for &b; # will be obtained from b.xml in the CWD

For streams, use "parseStream" rather than "parseString" in the above.

SplitQName(qualifiedName) -> (prefix, localName)

where 'qualifiedName' is a QName according to XML Namespaces 1.0 <http://www.w3.org/TR/REC-xml-names>. returns the name parts according to the spec.
