#1152 — XML VFS 1.0.1 for Midnight Commander

Hello!

I'm pleased to announce an XML Virtual FileSystem for Midnight Commander
version 1.0.1.


WHAT IS IT
   View an XML file in Midnight Commander as a filesystem.


WHAT'S NEW in version 1.0.1 (2013-11-24)
   Fixed a few minor bugs.

WHAT'S NEW in version 1.0.0 (2013-11-23)
   With lxml.etree-based implementation show only child namespaces
   (calculated as combined namespaces minus parent's namespaces).

WHAT'S NEW in version 0.6.0 (2013-11-22)
   Refactored _list() and attrs2text() to be completely generic.

WHAT'S NEW in version 0.5.0 (2013-11-19)
   Added lxml.etree-based implementation.

WHAT'S NEW in version 0.4.0 (2013-11-19)
   Added ElementTree-based implementation.

WHAT'S NEW in version 0.3.0 (2013-11-16)
   Initial release. Implementation based on minidom.


WHERE TO GET
   Home page: http://phdru.name/Software/mc/xml.html
   Download:  http://phdru.name/Software/mc/xml
    git clone http://git.phdru.name/extfs.d.git
     git clone git://git.phdru.name/extfs.d.git

   Installation instructions: http://phdru.name/Software/mc/INSTALL.html


The VFS represents tags as directories; the directories are numbered to
distinguish tags with the same name; numbering also helps to sort tags by their
order in XML instead of sorting them by name. Attributes, text nodes and
comments are represented as text files; attributes are shown in a file named
"attributes", attributes are listed in the file as name=value lines (I
deliberately ignore a small chance of newline characters in values); names and
values are reencoded to the console encoding. Text nodes and comments are
collected in a file named "text", stripped and reencoded. The filesystem is
read-only.

Implementation based on minidom doesn't understand namespaces, it just shows
them among other attributes. ElementTree-based implementation doesn't show
namespaces at all. Implementation based on lxml.etree shows namespaces in a
separate file "namespaces".

It is useful to have a top-down view on an XML structure but it's especially
convenient to extract text values from tags. One can get, for example, a
base64-encoded image - just walk down the VFS to the tag's directory and copy
its text file to a real file.

The VFS was inspired by a FUSE xmlfs: https://github.com/halhen/xmlfs
