    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 
    69 New in libxml2dom 0.3.6 (Changes since libxml2dom 0.3.5)
    70 --------------------------------------------------------
    71 
    72   * Added cloneNode almost as a synonym for importNode (which, unlike in the
    73     DOM specification, is present on all nodes).
    74   * Introduced Debian stable package details - suggested by Robert Siemer.
    75   * Changed libxml2mod import details to try libxmlmods - suggested by Lucian
    76     Wischik.
    77 
    78 New in libxml2dom 0.3.5 (Changes since libxml2dom 0.3.4)
    79 --------------------------------------------------------
    80 
    81   * Fixed nodeType for HTML document elements - reported by Robert Siemer.
    82   * Fixed string results from XPath expressions - reported by Robert Siemer.
    83 
    84 New in libxml2dom 0.3.4 (Changes since libxml2dom 0.3.3)
    85 --------------------------------------------------------
    86 
    87   * Attempted to introduce generated prefixes for attributes having namespaces
    88     but whose names are unprefixed.
    89   * Added support for xmlns attribute retrieval (getAttributeNS) and detection
    90     (hasAttributeNS).
    91   * Added the length attribute to NamedNodeMap; renamed the length method on
    92     NodeList, adding a length attribute.
    93 
    94 New in libxml2dom 0.3.3 (Changes since libxml2dom 0.3.2)
    95 --------------------------------------------------------
    96 
    97   * Removed redundant weakref usage.
    98   * Added explicit copyright and licensing information to source files.
    99 
   100 New in libxml2dom 0.3.2 (Changes since libxml2dom 0.3.1)
   101 --------------------------------------------------------
   102 
   103   * Improved the xmlns attribute creation controls.
   104 
   105 New in libxml2dom 0.3.1 (Changes since libxml2dom 0.3)
   106 ------------------------------------------------------
   107 
   108   * Fixed empty namespace declarations on elements created with namespaceURI
   109     set to None. Previously, such declarations were missing.
   110   * Fixed attribute creation and introduced stricter controls over the
   111     construction of xmlns attributes.
   112 
   113 New in libxml2dom 0.3 (Changes since libxml2dom 0.2.4)
   114 ------------------------------------------------------
   115 
   116   * Imposed much stricter tests on strings used with the libxml2dom API.
   117     Strings given as arguments to methods and functions must now only contain
   118     ASCII characters; any other character data must be provided as Unicode
   119     objects. This change fixes various issues with XPath expressions, and
   120     quite probably various other things.
   121   * Fixed parentNode on Document objects (which caused xml.dom.ext.PrettyPrint
   122     to crash).
   123   * Added some support for the doctype attribute and related information.
   124   * libxml2dom is now licensed under the LGPL - see docs/COPYING.txt for
   125     details.
   126 
   127 New in libxml2dom 0.2.4 (Changes since libxml2dom 0.2.3)
   128 --------------------------------------------------------
   129 
   130   * Fixed Unicode conversions in the Node's xpath method.
   131 
   132 New in libxml2dom 0.2.3 (Changes since libxml2dom 0.2.2)
   133 --------------------------------------------------------
   134 
   135   * Fixed the parse function's docstring.
   136   * Added the owner element to obtained attribute nodes.
   137   * Fixed Debian package changelog distribution identifiers.
   138 
   139 New in libxml2dom 0.2.2 (Changes since libxml2dom 0.2.1)
   140 --------------------------------------------------------
   141 
   142   * Fixed exception raising in parseURI, adding a docstring to explain the
   143     current limitations around HTML parsing.
   144 
   145 New in libxml2dom 0.2.1 (Changes since libxml2dom 0.2)
   146 ------------------------------------------------------
   147 
   148   * Moved libxml2macro script to the tools directory.
   149   * Added getElementsByTagNameNS.
   150   * Added a normalize implementation.
   151   * Added HTML parsing support.
   152   * Added prettyprinting support.
   153   * Fixed parseURI.
   154   * Introduced better testing for Unicode objects, especially since things
   155     like rdflib like to subclass the unicode type, and it might be more
   156     convenient to detect such subclasses and convert their values
   157     automatically.
   158   * Improved some of the API documentation.
   159   * Introduced better suppression of warnings, network access, and other
   160     potentially intrusive libxml2 features.
   161   * Reorganised the documentation, expanding the README.txt file at the
   162     expense of the HTML documentation, but removing older, less relevant
   163     information.
   164   * Added Debian package support.
   165 
   166 New in libxml2dom 0.2 (Changes since libxml2dom 0.1.3)
   167 ------------------------------------------------------
   168 
   169   * Adopted libxml2macro code within the libxml2dom classes, removing any
   170     dependencies on the libxml2 module - this makes everything much faster
   171     and virtually removes any necessity to use libxml2macro.
   172   * Improved attribute and document node handling.
   173   * Introduced document reference management.
   174   * Introduced NodeList wrapper objects.
   175 
   176 New in libxml2dom 0.1.3 (Changes since libxml2dom 0.1.2)
   177 --------------------------------------------------------
   178 
   179   * Fixed createElement.
   180   * Introduced experimental libxml2macro tools, tests and libraries.
   181 
   182 New in libxml2dom 0.1.2 (Changes since libxml2dom 0.1.1)
   183 --------------------------------------------------------
   184 
   185   * Fixed getAttributeNode and getAttributeNodeNS.
   186   * Added comment node creation.
   187   * Fixed empty namespace usage with elements and attributes.
   188   * Introduced usage of the libxml2 file and memory parsing features.
   189   * Introduced suppression of DTD retrieval and validation as the default
   190     behaviour.
   191   * Added experimental XPath method support.
   192 
   193 New in libxml2dom 0.1.1
   194 -----------------------
   195 
   196   * Fixed text node creation.
   197   * Fixed setAttributeNS.
   198   * Added encoding parameters to convenience methods.
   199   * Added the missing previousSibling property.
   200   * Added release number to the package.
   201

   218 Making Packages
   219 ---------------
   220 
   221 To make Debian-based packages:
   222 
   223   1. Create new package directories under packages if necessary.
   224   2. Make a symbolic link in the distribution's root directory to keep the
   225      Debian tools happy; choose one of the following:
   226 
   227      ln -s packages/ubuntu-hoary/python2.4-libxml2dom/debian/
   228      ln -s packages/debian-stable/python2.3-libxml2dom/debian/
   229 
   230   3. Run the package builder:
   231 
   232      dpkg-buildpackage -rfakeroot
   233 
   234   4. Locate and tidy up the packages in the parent directory of the
   235      distribution's root directory.
