Fred Drake d157237d51 For Python 2.2, do not use __getattr__(), only use computed properties.
This is probably a little bit faster, but mostly is just cleaner code.
The old-style support is still used for Python versions < 2.2 so this
source file can be shared with PyXML.

Fred Drake 575712eaca Tighten up the new NodeList implementation.
Clean up a little; do not create an alias that is only used once, or store
attributes with constant values in an instance.
2001-09-28 20:25:45 +00:00
Fred Drake 3ac6a09eed For Python 2.2 and newer, actually support the full NodeList interface by
subclassing list to add the length and item() attributes.

Fred Drake fbe7b4fc8c Make the implementations of getElementsByTagName() and
getElementsByTagNameNS() consistent in form as well as functionality
(cosmetic).
2001-07-04 06:25:53 +00:00
Martin v. Löwis ed525fb0df Fix getElementsByTagNameNS:
- actually return a result
  - Compare with tag.localName in getElementsByTagNameNSHelper

Fred Drake 33d2b84b2c CharacterData methods: Update self.length on changes instead of extended
the __getattr__() handler.

Text.splitText():  Update the length and nodeValue attributes.
2001-04-04 15:15:18 +00:00
Fred Drake 87432f42f9 Add support for the CharacterData methods, CDATASection. 2001-04-04 14:09:46 +00:00
Martin v. Löwis cb67ea1d6e Initialize Attr.value with empty string in createAttribute*, as per DOM
spec. Closes bug #412036.
Also reindent toprettyxml.

Fred Drake 6526bf863e When creating an attribute node using createAttribute() or
createAttributeNS(), use the parallel setAttributeNode() or
setAttributeNodeNS() to add the node to the document -- do not assume
that setAttributeNode() will operate properly for both.
2001-03-23 04:39:24 +00:00
Martin v. Löwis 126f2f62db Patch #407965: Improve Level 2 conformance of minidom
- addition of a DocumentFragment implementation and createDocumentFragment method
- proper setting of ownerDocument for all nodes
- setting of namespaceURI to None in Element as a class attribute
- addition of setAttributeNodeNS and removeAttributeNodeNS as aliases
  for setAttributeNode and removeAttributeNode
- support for inheriting from DOMImplementation to extend it with
  additional features (to override the Document class)
in pulldom:
- support for nodes (comment and PI) that occur before he document element;
  that became necessary as pulldom now delays creation of the document
  until it has the document element.

Martin v. Löwis 7edbd4ffb4 Patch #103885: Add dynamic registration and lookup of DOM implementations. 2001-02-22 14:05:50 +00:00
Andrew M. Kuchling bc8f72cccc Patch #103854: raises an exception if a non-Attr node is passed to
NamedNodeMap.setNamedItem().  Martin, should I sync the PyXML tree, too,
 or do you want to do it?  (I don't know if you're wrapping the 0.6.4
 release right now.)
2001-02-21 01:30:26 +00:00
Fred Drake b6a4425392 DOMException._get_code():
New method; this is the "alternate" access to the exception code.
    (Useful for Python DOM implementations that support the accessor
    method approach to retrieving attribute values.)
2001-02-19 14:57:02 +00:00
Martin v. Löwis b417be2ad9 Do not allow empty qualifiedName in createDocument.
Rearrange pulldom to create documents with root element.
Provide clear methods so that the ContentHandler releases its hold on the
document.

Martin v. Löwis 46fa39ab1d Add toprettyxml method into minidom, closes patch #103471. 2001-02-06 00:14:08 +00:00
Guido van Rossum 9e1fe1ec67 A couple of changes to make this more conformant. MvL and Uche agree.
This will make it incompatible with the version found in Python 2.0.
Does this need to be done to PyXML too?

Changes that might break existing code are marked with (!) below.

- Formatting nit: no spaces inside parentheses: foo( a ) -> foo(a).

- Break long lines.

- (!) Fix getAttribute() and getAttributeNS() to return "" instead of
  raising KeyError when the attribute is not found.

- (!) Fix getAttributeNodeNS() to return None instead of raising
  KeyError.  (Curiously, getAttributeNode() already did this.)

- Added hasAttributes(), which returns true iff the node has any
  attributes.  )This is DOM level 3.)

- (!) In createDocument(), if the qualified name is not empty,
  actually create and insert the first element with that name (this
  will become doc.documentElement).  MvL believes that it should be an
  error to specify an empty qualified name; I'm not going there today,
  since it would require making a matching change to pulldom.  Maybe
  MvL will do this.

- In Document.writexml(), insert an xml declaration at the top.  (This
  doesn't include the encoding since there's no way to specify the
  encoding.  If that's preferred, all writexml() methods should be
  fixed to support an optional encoding argument that they pass to
  each other -- and they should use it to encode all text they write,
  too.  Later.)

Guido van Rossum 795ad56b31 Don't get fooled by an empty prefix with a valid namespaceURI -- in
this case, the code used to generate invalid tags and attribute names
with a leading colon, e.g. <:tag> or <tag :attr="foo">.
2001-02-05 18:50:15 +00:00
Fred Drake 2523977fb2 Added Node.isSameNode() support. 2001-02-02 19:40:19 +00:00

Fred Drake daa823ad9a Text.__init__(): Make sure the data parameter is a string (8-bit or
Unicode); raise TypeError if not.

This closes SF bug #126866.

Andrew M. Kuchling 291ed4fb3f Patch #102485 ] Check for legal children when adding children to a DOM node 2000-12-31 03:50:23 +00:00
Martin v. Löwis 011ea47577 Merge with 1.8 of pulldom.py:
Use types.UnicodeType if available, not type(u"").
2000-12-28 18:43:02 +00:00
Martin v. Löwis 156c337f66 Merge changes up to 1.10 from PyXML:
- implement hasAttribute and hasAttributeNS (1.7)
- Node.replaceChild():  Update the sibling nodes to point to newChild.  Set
  the .nextSibling attribute on oldChild instead of adding a .newChild
  attribute (1.9).
2000-12-28 18:40:56 +00:00
Andrew M. Kuchling 04a45e9bb1 Patch #102492, fixing bug #116677:
give minidom.py behaviour that complies with the DOM Level 1 REC,
    which says that when a node newChild is added to the tree, "if the
    newChild is already in the tree, it is first removed."

    pulldom.py is patched to use the public minidom interface instead
    of setting .parentNode itself.  Possibly this reduces pulldom's
    efficiency; someone else will have to pronounce on that.

Fred Drake 279aa6cabc DOMException.__init__(): Remember to pass self to Exception.__init__(). 2000-12-15 21:07:59 +00:00
Fred Drake f7cf40d331 Lots of small bug fixes and DOM API conformance improvements:
Make Node inherit from xml.dom.Node to pick up the NodeType values
defined by the W3C recommendation.

When raising AttributeError, be sure to provide the name of the attribute
that does not exist.

Node.normalize():  Make sure we do not allow an empty text node to survive
                   as the first child; update the sibling links properly.

_getElementsByTagNameNSHelper():  Make recursive calls using the right
                                  number of parameters.

Attr.__setattr__():  Be sure to update name and nodeName at the same time
                     since they are synonyms for this node type.

AttributeList:  Renamed to NamedNodeMap (AttributeList maintained as an
                alias).  Compute the length attribute dynamically to allow
                the underlying structures to mutate.

AttributeList.item():  Call .keys() on the dictionary rather than using
                       self.keys() for performance.

AttributeList.setNamedItem(), .setNamedItemNS():
        Added methods.

Text.splitText():
        Added method.

DocumentType:
        Added implementation class.

DOMImplementation:
        Added implementation class.

Document.appendChild():  Do not allow a second document element to be added.

Document.documentElement:  Find this dynamically, so that one can be
        removed and another added.

Document.unlink():  Clear the doctype attribute.

_get_StringIO():  Only use the StringIO module; cStringIO does not support
                  Unicode.
2000-12-14 18:16:11 +00:00
Fred Drake c16adce273 Adjust PullDOM to use a DOMImplementation instance to create new Document
objects; uses minidom if one is not provided to the constructor.

parse():  Pick up the default_bufsize default value dynamically so that
          the value in the module may be (meaningfully) changed at runtime.

This (partially) closes patch #102477.
2000-12-14 18:00:18 +00:00
Fred Drake 5d1b5eaf55 Add code to DOMException to ensure it cannot be instantiated directly,
since the API documentation will state specifically that the specializations
must be used by the DOM implementations.
2000-12-13 16:35:53 +00:00
Martin v. Löwis 64acf1db22 Add standard DOM exception hierarchy. 2000-12-13 14:21:07 +00:00
Fred Drake 6bcf4c2a0b Update the docstring.
Add a Node class that defines the NodeType constants, based on discussion
in the XML-SIG.
2000-12-11 22:29:23 +00:00
Fred Drake 4ccf4a1e8a Reduce the visibility of imported modules for cleaner "from ... import *"
behavior.

Added support for the Attr.ownerElement attribute.

Everywhere:  Define constant object attributes in the classes rather than
on the instances during object construction.  This reduces the amount of
work needed for object construction and destruction; these need to be
lightweight operations on a DOM.

Node._get_firstChild(),
Node._get_lastChild():  Return None if there are no children (required for
        compliance with DOM level 1).

Node.insertBefore():  If refChild is None, append the new node instead of
        failing (required for compliance).  Also, update the sibling
        relationships.  Return the inserted node (required for compliance).

Node.appendChild():  Update the parent of the appended node.

Node.replaceChild():  Actually replace the old child!  Update the parent
        and sibling relationships of both the old and new children.  Return
        the replaced child (required for compliance).

Node.normalize():  Implemented the normalize() method.  Required for
        compliance, but missing from the release.  Useful for joining
        adjacent Text nodes into a single node for easier processing.

Node.cloneNode():  Actually make this work.  Don't let the new node share
        the instance __dict__ with the original.  Do proper recursion if
        doing a "deep" clone.  Move the attribute cloning out of the base
        class, since only Element is supposed to have attributes.

Node.unlink():  Simplify handling of child nodes for efficiency, and
        remove the attribute handling since only Element nodes support
        attributes.

Attr.cloneNode():  Extend this to clear the ownerElement attribute in
        the clone.

AttributeList.items(),
AttributeList.itemsNS():  Slight performance improvement (avoid lambda).

Element.cloneNode():  Extend Node.cloneNode() with support for the
        attributes.  Clone the Attr objects after creating the underlying
        clone.

Element.unlink():  Clean out the attributes here instead of in the base
        class, since this is the only class that will have them.

Element.toxml():  Adjust to create only one AttributeList instance; minor
        efficiency improvement.

_nssplit():  No need to re-import string.

Document.__init__():  No longer needed once constant attributes are
        initialized in the class itself.

Document.createElementNS(),
Document.createAttributeNS():  Use the defined constructors rather than
        directly access the classes.

_get_StringIO():  New function.  Create an output StringIO using the most
        efficient available flavor.

parse(),
parseString():  Import pulldom here instead of in the public namespace of
        the module.
