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
71 New in libxml2dom 0.3.6 (Changes since libxml2dom 0.3.5)
72 --------------------------------------------------------
73
74 * Added cloneNode almost as a synonym for importNode (which, unlike in the
75 DOM specification, is present on all nodes).
76 * Introduced Debian stable package details - suggested by Robert Siemer.
77 * Changed libxml2mod import details to try libxmlmods - suggested by Lucian
78 Wischik.
79
80 New in libxml2dom 0.3.5 (Changes since libxml2dom 0.3.4)
81 --------------------------------------------------------
82
83 * Fixed nodeType for HTML document elements - reported by Robert Siemer.
84 * Fixed string results from XPath expressions - reported by Robert Siemer.
85
86 New in libxml2dom 0.3.4 (Changes since libxml2dom 0.3.3)
87 --------------------------------------------------------
88
89 * Attempted to introduce generated prefixes for attributes having namespaces
90 but whose names are unprefixed.
91 * Added support for xmlns attribute retrieval (getAttributeNS) and detection
92 (hasAttributeNS).
93 * Added the length attribute to NamedNodeMap; renamed the length method on
94 NodeList, adding a length attribute.
95
96 New in libxml2dom 0.3.3 (Changes since libxml2dom 0.3.2)
97 --------------------------------------------------------
98
99 * Removed redundant weakref usage.
100 * Added explicit copyright and licensing information to source files.
101
102 New in libxml2dom 0.3.2 (Changes since libxml2dom 0.3.1)
103 --------------------------------------------------------
104
105 * Improved the xmlns attribute creation controls.
106
107 New in libxml2dom 0.3.1 (Changes since libxml2dom 0.3)
108 ------------------------------------------------------
109
110 * Fixed empty namespace declarations on elements created with namespaceURI
111 set to None. Previously, such declarations were missing.
112 * Fixed attribute creation and introduced stricter controls over the
113 construction of xmlns attributes.
114
115 New in libxml2dom 0.3 (Changes since libxml2dom 0.2.4)
116 ------------------------------------------------------
117
118 * Imposed much stricter tests on strings used with the libxml2dom API.
119 Strings given as arguments to methods and functions must now only contain
120 ASCII characters; any other character data must be provided as Unicode
121 objects. This change fixes various issues with XPath expressions, and
122 quite probably various other things.
123 * Fixed parentNode on Document objects (which caused xml.dom.ext.PrettyPrint
124 to crash).
125 * Added some support for the doctype attribute and related information.
126 * libxml2dom is now licensed under the LGPL - see docs/COPYING.txt for
127 details.
128
129 New in libxml2dom 0.2.4 (Changes since libxml2dom 0.2.3)
130 --------------------------------------------------------
131
132 * Fixed Unicode conversions in the Node's xpath method.
133
134 New in libxml2dom 0.2.3 (Changes since libxml2dom 0.2.2)
135 --------------------------------------------------------
136
137 * Fixed the parse function's docstring.
138 * Added the owner element to obtained attribute nodes.
139 * Fixed Debian package changelog distribution identifiers.
140
141 New in libxml2dom 0.2.2 (Changes since libxml2dom 0.2.1)
142 --------------------------------------------------------
143
144 * Fixed exception raising in parseURI, adding a docstring to explain the
145 current limitations around HTML parsing.
146
147 New in libxml2dom 0.2.1 (Changes since libxml2dom 0.2)
148 ------------------------------------------------------
149
150 * Moved libxml2macro script to the tools directory.
151 * Added getElementsByTagNameNS.
152 * Added a normalize implementation.
153 * Added HTML parsing support.
154 * Added prettyprinting support.
155 * Fixed parseURI.
156 * Introduced better testing for Unicode objects, especially since things
157 like rdflib like to subclass the unicode type, and it might be more
158 convenient to detect such subclasses and convert their values
159 automatically.
160 * Improved some of the API documentation.
161 * Introduced better suppression of warnings, network access, and other
162 potentially intrusive libxml2 features.
163 * Reorganised the documentation, expanding the README.txt file at the
164 expense of the HTML documentation, but removing older, less relevant
165 information.
166 * Added Debian package support.
167
168 New in libxml2dom 0.2 (Changes since libxml2dom 0.1.3)
169 ------------------------------------------------------
170
171 * Adopted libxml2macro code within the libxml2dom classes, removing any
172 dependencies on the libxml2 module - this makes everything much faster
173 and virtually removes any necessity to use libxml2macro.
174 * Improved attribute and document node handling.
175 * Introduced document reference management.
176 * Introduced NodeList wrapper objects.
177
178 New in libxml2dom 0.1.3 (Changes since libxml2dom 0.1.2)
179 --------------------------------------------------------
180
181 * Fixed createElement.
182 * Introduced experimental libxml2macro tools, tests and libraries.
183
184 New in libxml2dom 0.1.2 (Changes since libxml2dom 0.1.1)
185 --------------------------------------------------------
186
187 * Fixed getAttributeNode and getAttributeNodeNS.
188 * Added comment node creation.
189 * Fixed empty namespace usage with elements and attributes.
190 * Introduced usage of the libxml2 file and memory parsing features.
191 * Introduced suppression of DTD retrieval and validation as the default
192 behaviour.
193 * Added experimental XPath method support.
194
195 New in libxml2dom 0.1.1
196 -----------------------
197
198 * Fixed text node creation.
199 * Fixed setAttributeNS.
200 * Added encoding parameters to convenience methods.
201 * Added the missing previousSibling property.
202 * Added release number to the package.
203

220 Making Packages
221 ---------------
222
223 To make Debian-based packages:
224
225 1. Create new package directories under packages if necessary.
226 2. Make a symbolic link in the distribution's root directory to keep the
227 Debian tools happy; choose one of the following:
228
229 ln -s packages/ubuntu-hoary/python2.4-libxml2dom/debian/
230 ln -s packages/debian-stable/python2.3-libxml2dom/debian/
231
232 3. Run the package builder:
233
234 dpkg-buildpackage -rfakeroot
235
236 4. Locate and tidy up the packages in the parent directory of the
237 distribution's root directory.
