    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   * Introduced an Implementation class, permitting specialised node creation.
    65   * Added SVG-specific document support.
    66 
    67 New in libxml2dom 0.3.6 (Changes since libxml2dom 0.3.5)
    68 --------------------------------------------------------
    69 
    70   * Added cloneNode almost as a synonym for importNode (which, unlike in the
    71     DOM specification, is present on all nodes).
    72   * Introduced Debian stable package details - suggested by Robert Siemer.
    73   * Changed libxml2mod import details to try libxmlmods - suggested by Lucian
    74     Wischik.
    75 
    76 New in libxml2dom 0.3.5 (Changes since libxml2dom 0.3.4)
    77 --------------------------------------------------------
    78 
    79   * Fixed nodeType for HTML document elements - reported by Robert Siemer.
    80   * Fixed string results from XPath expressions - reported by Robert Siemer.
    81 
    82 New in libxml2dom 0.3.4 (Changes since libxml2dom 0.3.3)
    83 --------------------------------------------------------
    84 
    85   * Attempted to introduce generated prefixes for attributes having namespaces
    86     but whose names are unprefixed.
    87   * Added support for xmlns attribute retrieval (getAttributeNS) and detection
    88     (hasAttributeNS).
    89   * Added the length attribute to NamedNodeMap; renamed the length method on
    90     NodeList, adding a length attribute.
    91 
    92 New in libxml2dom 0.3.3 (Changes since libxml2dom 0.3.2)
    93 --------------------------------------------------------
    94 
    95   * Removed redundant weakref usage.
    96   * Added explicit copyright and licensing information to source files.
    97 
    98 New in libxml2dom 0.3.2 (Changes since libxml2dom 0.3.1)
    99 --------------------------------------------------------
   100 
   101   * Improved the xmlns attribute creation controls.
   102 
   103 New in libxml2dom 0.3.1 (Changes since libxml2dom 0.3)
   104 ------------------------------------------------------
   105 
   106   * Fixed empty namespace declarations on elements created with namespaceURI
   107     set to None. Previously, such declarations were missing.
   108   * Fixed attribute creation and introduced stricter controls over the
   109     construction of xmlns attributes.
   110 
   111 New in libxml2dom 0.3 (Changes since libxml2dom 0.2.4)
   112 ------------------------------------------------------
   113 
   114   * Imposed much stricter tests on strings used with the libxml2dom API.
   115     Strings given as arguments to methods and functions must now only contain
   116     ASCII characters; any other character data must be provided as Unicode
   117     objects. This change fixes various issues with XPath expressions, and
   118     quite probably various other things.
   119   * Fixed parentNode on Document objects (which caused xml.dom.ext.PrettyPrint
   120     to crash).
   121   * Added some support for the doctype attribute and related information.
   122   * libxml2dom is now licensed under the LGPL - see docs/COPYING.txt for
   123     details.
   124 
   125 New in libxml2dom 0.2.4 (Changes since libxml2dom 0.2.3)
   126 --------------------------------------------------------
   127 
   128   * Fixed Unicode conversions in the Node's xpath method.
   129 
   130 New in libxml2dom 0.2.3 (Changes since libxml2dom 0.2.2)
   131 --------------------------------------------------------
   132 
   133   * Fixed the parse function's docstring.
   134   * Added the owner element to obtained attribute nodes.
   135   * Fixed Debian package changelog distribution identifiers.
   136 
   137 New in libxml2dom 0.2.2 (Changes since libxml2dom 0.2.1)
   138 --------------------------------------------------------
   139 
   140   * Fixed exception raising in parseURI, adding a docstring to explain the
   141     current limitations around HTML parsing.
   142 
   143 New in libxml2dom 0.2.1 (Changes since libxml2dom 0.2)
   144 ------------------------------------------------------
   145 
   146   * Moved libxml2macro script to the tools directory.
   147   * Added getElementsByTagNameNS.
   148   * Added a normalize implementation.
   149   * Added HTML parsing support.
   150   * Added prettyprinting support.
   151   * Fixed parseURI.
   152   * Introduced better testing for Unicode objects, especially since things
   153     like rdflib like to subclass the unicode type, and it might be more
   154     convenient to detect such subclasses and convert their values
   155     automatically.
   156   * Improved some of the API documentation.
   157   * Introduced better suppression of warnings, network access, and other
   158     potentially intrusive libxml2 features.
   159   * Reorganised the documentation, expanding the README.txt file at the
   160     expense of the HTML documentation, but removing older, less relevant
   161     information.
   162   * Added Debian package support.
   163 
   164 New in libxml2dom 0.2 (Changes since libxml2dom 0.1.3)
   165 ------------------------------------------------------
   166 
   167   * Adopted libxml2macro code within the libxml2dom classes, removing any
   168     dependencies on the libxml2 module - this makes everything much faster
   169     and virtually removes any necessity to use libxml2macro.
   170   * Improved attribute and document node handling.
   171   * Introduced document reference management.
   172   * Introduced NodeList wrapper objects.
   173 
   174 New in libxml2dom 0.1.3 (Changes since libxml2dom 0.1.2)
   175 --------------------------------------------------------
   176 
   177   * Fixed createElement.
   178   * Introduced experimental libxml2macro tools, tests and libraries.
   179 
   180 New in libxml2dom 0.1.2 (Changes since libxml2dom 0.1.1)
   181 --------------------------------------------------------
   182 
   183   * Fixed getAttributeNode and getAttributeNodeNS.
   184   * Added comment node creation.
   185   * Fixed empty namespace usage with elements and attributes.
   186   * Introduced usage of the libxml2 file and memory parsing features.
   187   * Introduced suppression of DTD retrieval and validation as the default
   188     behaviour.
   189   * Added experimental XPath method support.
   190 
   191 New in libxml2dom 0.1.1
   192 -----------------------
   193 
   194   * Fixed text node creation.
   195   * Fixed setAttributeNS.
   196   * Added encoding parameters to convenience methods.
   197   * Added the missing previousSibling property.
   198   * Added release number to the package.
   199

   216 Making Packages
   217 ---------------
   218 
   219 To make Debian-based packages:
   220 
   221   1. Create new package directories under packages if necessary.
   222   2. Make a symbolic link in the distribution's root directory to keep the
   223      Debian tools happy; choose one of the following:
   224 
   225      ln -s packages/ubuntu-hoary/python2.4-libxml2dom/debian/
   226      ln -s packages/debian-stable/python2.3-libxml2dom/debian/
   227 
   228   3. Run the package builder:
   229 
   230      dpkg-buildpackage -rfakeroot
   231 
   232   4. Locate and tidy up the packages in the parent directory of the
   233      distribution's root directory.
