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 Python Tested with Python 2.4.
24 Python releases from 2.2 onwards should be compatible with
25 libxml2dom. The principal requirement from such releases is the
26 new-style class support which permits the use of properties in
27 the libxml2dom implementation.
28
29 Testing
30 -------
31
32 Some of the tests require libxml2macro.py to be run on the test source code
33 first. Read the docstrings for the various test files before attempting to run
34 any of them. See also docs/NOTES_libxml2macro.txt for more information. Note
35 that such tests are retained for historical purposes and/or curiosity since
36 libxml2macro.py is no longer supported.
37
38 Issues
39 ------
40
41 The presence of xmlns attributes in serialised documents was called into
42 question, and the tests/namespace.py and tests/namespace2.py files attempt to
43 show the current behaviour of libxml2dom.
44
45 Use of importNode seems to cause some kind of memory issue, probably related
46 to nodes being shared across documents. This was observed in libxml2 2.6.0 but
47 appears to be fixed in libxml2 2.6.16.
48
49 Even compared to minidom, importNode may seem very slow (even the
50 libxml2dom.macrolib implementation, too). A way is needed to get libxml2 to do
51 the node copying itself.
52
53 New in libxml2dom 0.3.3 (Changes since libxml2dom 0.3.2)
54 --------------------------------------------------------
55
56 * Removed redundant weakref usage.
57 * Added explicit copyright and licensing information to source files.
58
59 New in libxml2dom 0.3.2 (Changes since libxml2dom 0.3.1)
60 --------------------------------------------------------
61
62 * Improved the xmlns attribute creation controls.
63
64 New in libxml2dom 0.3.1 (Changes since libxml2dom 0.3)
65 ------------------------------------------------------
66
67 * Fixed empty namespace declarations on elements created with namespaceURI
68 set to None. Previously, such declarations were missing.
69 * Fixed attribute creation and introduced stricter controls over the
70 construction of xmlns attributes.
71
72 New in libxml2dom 0.3 (Changes since libxml2dom 0.2.4)
73 ------------------------------------------------------
74
75 * Imposed much stricter tests on strings used with the libxml2dom API.
76 Strings given as arguments to methods and functions must now only contain
77 ASCII characters; any other character data must be provided as Unicode
78 objects. This change fixes various issues with XPath expressions, and
79 quite probably various other things.
80 * Fixed parentNode on Document objects (which caused xml.dom.ext.PrettyPrint
81 to crash).
82 * Added some support for the doctype attribute and related information.
83 * libxml2dom is now licensed under the LGPL - see docs/COPYING.txt for
84 details.
85
86 New in libxml2dom 0.2.4 (Changes since libxml2dom 0.2.3)
87 --------------------------------------------------------
88
89 * Fixed Unicode conversions in the Node's xpath method.
90
91 New in libxml2dom 0.2.3 (Changes since libxml2dom 0.2.2)
92 --------------------------------------------------------
93
94 * Fixed the parse function's docstring.
95 * Added the owner element to obtained attribute nodes.
96 * Fixed Debian package changelog distribution identifiers.
97
98 New in libxml2dom 0.2.2 (Changes since libxml2dom 0.2.1)
99 --------------------------------------------------------
100
101 * Fixed exception raising in parseURI, adding a docstring to explain the
102 current limitations around HTML parsing.
103
104 New in libxml2dom 0.2.1 (Changes since libxml2dom 0.2)
105 ------------------------------------------------------
106
107 * Moved libxml2macro script to the tools directory.
108 * Added getElementsByTagNameNS.
109 * Added a normalize implementation.
110 * Added HTML parsing support.
111 * Added prettyprinting support.
112 * Fixed parseURI.
113 * Introduced better testing for Unicode objects, especially since things
114 like rdflib like to subclass the unicode type, and it might be more
115 convenient to detect such subclasses and convert their values
116 automatically.
117 * Improved some of the API documentation.
118 * Introduced better suppression of warnings, network access, and other
119 potentially intrusive libxml2 features.
120 * Reorganised the documentation, expanding the README.txt file at the
121 expense of the HTML documentation, but removing older, less relevant
122 information.
123 * Added Debian package support.
124
125 New in libxml2dom 0.2 (Changes since libxml2dom 0.1.3)
126 ------------------------------------------------------
127
128 * Adopted libxml2macro code within the libxml2dom classes, removing any
129 dependencies on the libxml2 module - this makes everything much faster
130 and virtually removes any necessity to use libxml2macro.
131 * Improved attribute and document node handling.
132 * Introduced document reference management.
133 * Introduced NodeList wrapper objects.
134
135 New in libxml2dom 0.1.3 (Changes since libxml2dom 0.1.2)
136 --------------------------------------------------------
137
138 * Fixed createElement.
139 * Introduced experimental libxml2macro tools, tests and libraries.
140
141 New in libxml2dom 0.1.2 (Changes since libxml2dom 0.1.1)
142 --------------------------------------------------------
143
144 * Fixed getAttributeNode and getAttributeNodeNS.
145 * Added comment node creation.
146 * Fixed empty namespace usage with elements and attributes.
147 * Introduced usage of the libxml2 file and memory parsing features.
148 * Introduced suppression of DTD retrieval and validation as the default
149 behaviour.
150 * Added experimental XPath method support.
151
152 New in libxml2dom 0.1.1
153 -----------------------
154
155 * Fixed text node creation.
156 * Fixed setAttributeNS.
157 * Added encoding parameters to convenience methods.
158 * Added the missing previousSibling property.
159 * Added release number to the package.

177 Making Packages
178 ---------------
179
180 To make Debian-based packages:
181
182 1. Create new package directories under packages if necessary.
183 2. Make a symbolic link in the distribution's root directory to keep the
184 Debian tools happy:
185
186 ln -s packages/ubuntu-hoary/python2.4-libxml2dom/debian/
187
188 3. Run the package builder:
189
190 dpkg-buildpackage -rfakeroot
191
192 4. Locate and tidy up the packages in the parent directory of the
193 distribution's root directory.
