16 Dependencies
17 ------------
18
19 libxml2 Tested with libxml2 2.6.17.
20 Use --with-python=<path to python executable> if building from
21 source. Previous releases of libxml2 in the 2.6 series may work,
22 but releases before 2.6.16 are not recommended.
23
24 For Windows users, see also the packages for libxml2, available
25 from the following site:
26
27 http://users.skynet.be/sbi/libxml-python/
28
29 Python Tested with Python 2.4.
30 Python releases from 2.2 onwards should be compatible with
31 libxml2dom. The principal requirement from such releases is the
32 new-style class support which permits the use of properties in
33 the libxml2dom implementation.
34
35 Testing
36 -------
37
38 Some of the tests require libxml2macro.py to be run on the test source code
39 first. Read the docstrings for the various test files before attempting to run
40 any of them. See also docs/NOTES_libxml2macro.txt for more information. Note
41 that such tests are retained for historical purposes and/or curiosity since
42 libxml2macro.py is no longer supported.
43
44 Issues
45 ------
46
47 The presence of xmlns attributes in serialised documents was called into
48 question, and the tests/namespace*.py files attempt to show the current
49 behaviour of libxml2dom.
50
51 Use of importNode seems to cause some kind of memory issue, probably related
52 to nodes being shared across documents. This was observed in libxml2 2.6.0 but
53 appears to be fixed in libxml2 2.6.16.
54
55 Even compared to minidom, importNode may seem very slow (even the
56 libxml2dom.macrolib implementation, too). A way is needed to get libxml2 to do
57 the node copying itself.
58
59 New in libxml2dom 0.4 (Changes since libxml2dom 0.3.6)
60 ------------------------------------------------------
61
62 * Changed the nodeValue property to return None for various node types, as
63 specified in the DOM specification (Level 3).
64 * Fixed various "not supported" exceptions and added tests which can raise
65 "wrong document" exceptions.
66 * Introduced an Implementation class, permitting specialised node creation.
67 * Added SVG-specific document support.
68 * Made parseURI work for HTML documents.
69 * Fixed getElementsByTagName(NS), as reported by Christian Seiler.
70 * Fixed previousSibling, nextSibling and parentNode crashes using
71 suggestions from Christian Seiler.
72 * Reintroduced node comparisons using suggestions from Christian Seiler.
73 * Added the textContent property to nodes.
74 * Added a getDOMImplementation function.
75 * Added an experimental events module.
76
77 New in libxml2dom 0.3.6 (Changes since libxml2dom 0.3.5)
78 --------------------------------------------------------
79
80 * Added cloneNode almost as a synonym for importNode (which, unlike in the
81 DOM specification, is present on all nodes).
82 * Introduced Debian stable package details - suggested by Robert Siemer.
83 * Changed libxml2mod import details to try libxmlmods - suggested by Lucian
84 Wischik.
85
86 New in libxml2dom 0.3.5 (Changes since libxml2dom 0.3.4)
87 --------------------------------------------------------
88
89 * Fixed nodeType for HTML document elements - reported by Robert Siemer.
90 * Fixed string results from XPath expressions - reported by Robert Siemer.
91
92 New in libxml2dom 0.3.4 (Changes since libxml2dom 0.3.3)
93 --------------------------------------------------------
94
95 * Attempted to introduce generated prefixes for attributes having namespaces
96 but whose names are unprefixed.
97 * Added support for xmlns attribute retrieval (getAttributeNS) and detection
98 (hasAttributeNS).
99 * Added the length attribute to NamedNodeMap; renamed the length method on
100 NodeList, adding a length attribute.
101
102 New in libxml2dom 0.3.3 (Changes since libxml2dom 0.3.2)
103 --------------------------------------------------------
104
105 * Removed redundant weakref usage.
106 * Added explicit copyright and licensing information to source files.
107
108 New in libxml2dom 0.3.2 (Changes since libxml2dom 0.3.1)
109 --------------------------------------------------------
110
111 * Improved the xmlns attribute creation controls.
112
113 New in libxml2dom 0.3.1 (Changes since libxml2dom 0.3)
114 ------------------------------------------------------
115
116 * Fixed empty namespace declarations on elements created with namespaceURI
117 set to None. Previously, such declarations were missing.
118 * Fixed attribute creation and introduced stricter controls over the
119 construction of xmlns attributes.
120
121 New in libxml2dom 0.3 (Changes since libxml2dom 0.2.4)
122 ------------------------------------------------------
123
124 * Imposed much stricter tests on strings used with the libxml2dom API.
125 Strings given as arguments to methods and functions must now only contain
126 ASCII characters; any other character data must be provided as Unicode
127 objects. This change fixes various issues with XPath expressions, and
128 quite probably various other things.
129 * Fixed parentNode on Document objects (which caused xml.dom.ext.PrettyPrint
130 to crash).
131 * Added some support for the doctype attribute and related information.
132 * libxml2dom is now licensed under the LGPL - see docs/COPYING.txt for
133 details.
134
135 New in libxml2dom 0.2.4 (Changes since libxml2dom 0.2.3)
136 --------------------------------------------------------
137
138 * Fixed Unicode conversions in the Node's xpath method.
139
140 New in libxml2dom 0.2.3 (Changes since libxml2dom 0.2.2)
141 --------------------------------------------------------
142
143 * Fixed the parse function's docstring.
144 * Added the owner element to obtained attribute nodes.
145 * Fixed Debian package changelog distribution identifiers.
146
147 New in libxml2dom 0.2.2 (Changes since libxml2dom 0.2.1)
148 --------------------------------------------------------
149
150 * Fixed exception raising in parseURI, adding a docstring to explain the
151 current limitations around HTML parsing.
152
153 New in libxml2dom 0.2.1 (Changes since libxml2dom 0.2)
154 ------------------------------------------------------
155
156 * Moved libxml2macro script to the tools directory.
157 * Added getElementsByTagNameNS.
158 * Added a normalize implementation.
159 * Added HTML parsing support.
160 * Added prettyprinting support.
161 * Fixed parseURI.
162 * Introduced better testing for Unicode objects, especially since things
163 like rdflib like to subclass the unicode type, and it might be more
164 convenient to detect such subclasses and convert their values
165 automatically.
166 * Improved some of the API documentation.
167 * Introduced better suppression of warnings, network access, and other
168 potentially intrusive libxml2 features.
169 * Reorganised the documentation, expanding the README.txt file at the
170 expense of the HTML documentation, but removing older, less relevant
171 information.
172 * Added Debian package support.
173
174 New in libxml2dom 0.2 (Changes since libxml2dom 0.1.3)
175 ------------------------------------------------------
176
177 * Adopted libxml2macro code within the libxml2dom classes, removing any
178 dependencies on the libxml2 module - this makes everything much faster
179 and virtually removes any necessity to use libxml2macro.
180 * Improved attribute and document node handling.
181 * Introduced document reference management.
182 * Introduced NodeList wrapper objects.
183
184 New in libxml2dom 0.1.3 (Changes since libxml2dom 0.1.2)
185 --------------------------------------------------------
186
187 * Fixed createElement.
188 * Introduced experimental libxml2macro tools, tests and libraries.
189
190 New in libxml2dom 0.1.2 (Changes since libxml2dom 0.1.1)
191 --------------------------------------------------------
192
193 * Fixed getAttributeNode and getAttributeNodeNS.
194 * Added comment node creation.
195 * Fixed empty namespace usage with elements and attributes.
196 * Introduced usage of the libxml2 file and memory parsing features.
197 * Introduced suppression of DTD retrieval and validation as the default
198 behaviour.
199 * Added experimental XPath method support.
200
201 New in libxml2dom 0.1.1
202 -----------------------
203
204 * Fixed text node creation.
205 * Fixed setAttributeNS.
206 * Added encoding parameters to convenience methods.
207 * Added the missing previousSibling property.
208 * Added release number to the package.

226 Making Packages
227 ---------------
228
229 To make Debian-based packages:
230
231 1. Create new package directories under packages if necessary.
232 2. Make a symbolic link in the distribution's root directory to keep the
233 Debian tools happy; choose one of the following:
234
235 ln -s packages/ubuntu-hoary/python2.4-libxml2dom/debian/
236 ln -s packages/debian-stable/python2.3-libxml2dom/debian/
237
238 3. Run the package builder:
239
240 dpkg-buildpackage -rfakeroot
241
242 4. Locate and tidy up the packages in the parent directory of the
243 distribution's root directory.
