Method Details [hide private]

__init__(self, filename, sent, tag, strip_space, stem)
(Constructor)

source code 

Create a new corpus view based on a specified XML file.

Note that the XMLCorpusView constructor does not take an encoding argument, because the unicode encoding is specified by the XML files themselves.

Parameters:
  • filename - The name of the underlying file.
  • sent - If true, include sentence bracketing.
  • tag - The name of the tagset to use, or None for no tags.
  • strip_space - If true, strip spaces from word tokens.
  • stem - If true, then substitute stems for words.
Overrides: xmldocs.XMLCorpusView.__init__

handle_elt(self, elt, context)

source code 

Convert an element into an appropriate value for inclusion in the view. Unless overridden by a subclass or by the elt_handler constructor argument, this method simply returns elt.

Parameters:
  • elt - The element that should be converted.
  • context - A string composed of element tags separated by forward slashes, indicating the XML context of the given element. For example, the string 'foo/bar/baz' indicates that the element is a baz element whose parent is a bar element and whose grandparent is a top-level foo element.
Returns:
The view value corresponding to elt.
Overrides: xmldocs.XMLCorpusView.handle_elt
