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
Methods
__init__(
self,
stream=<open file '<stdout>', mode 'w' at 0xb7e4f068>,
**wargs)
Convenience factory function for Markup writers (based on
xsl:output in XSLT)
simpleElement(
self,
tagName,
namespace=None,
extraNss=None,
attributes=None,
content=u'')
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
tagName - qualified name of the element (must be unicode)
namespace - optional namespace URI
attribute - 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
startElement(
self,
tagName,
namespace=None,
extraNss=None,
attributes=None)
Create a start tag with optional attributes. Must eventually
be matched with an endElement call
tagName - qualified name of the element (must be unicode)
namespace - optional namespace URI
attribute - optional dictionary mapping name to unicode value
the name can either be a unicode QName or a tuple
of (QName, namespace URI)
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
