Asp Forum - [ANN] LibXML-Ruby 0.3.6

LibXML-Ruby 0.3.6 is now available from Rubyforge. LibXML-Ruby is (as
you may have guessed) a C-language Ruby binding to the Gnome LibXML2
library, supporting a wide range of XML technologies and offering very
competitive performance across the board.

You can obtain LibXML-Ruby via Rubygems:

gem install libxml-ruby

Or as standard tarball/zip packages:

http://rubyforge.org/frs/?group_id=494&relea...

This release is essentially our 'ground zero' release after a recent
effort to revive the sleeping LibXML-Ruby project with the help of
original author Sean Chittenden. Although fixes for a number of bugs in
the build and the code are included, no new functionality has yet been
added. We are keen to gain feedback from the community, whether positive
or negative, with a view to fixing the direction of the project. Our
mailing list:

libxml-devel@rubyforge.org

You can find (a bit) more information, and API documentation, at the
project website on Rubyforge:

http://libxml.ruby...

(Please note, *not* xml-tools as was previously the case).

For more information on the XML technologies supported by LibXML2, or
for help obtaining or installing it, please see:

Will this library be renamed LibXML2-Ruby soon? The current name is
slightly misleading.

Yes, I have to agree. But the project was previously under the name
'libxml-ruby' and we wanted to get a release out quickly, with minimal
changes (beyond fixing things). This release should be completely
compatible with existing code, including the "require 'xml/libxml'"
part.

We're hoping to get feedback from this release and work that into the
next minor release, 0.4.0. Maybe between now and then we can slip a name
change in there ...

Tried to install it under windows and it failed because I didn't have Zlib.
This is with the ruby one click installer.

Thanks

Strange, because ZLib *is* included in the one-click installer.

(Wrong button, excuse the noise)

Does it include the zlib.h header ?

If so, OP could maybe try passing --with-zlib=<path> option to a manual
install, but I'm not sure yet how it could work with gems...

No, it just includes the executable. The release notes show the exact
version, so you could download the source and extract the header.

Great!

Could you please explain to us uninitiated the advantages (and
disadvantages) of this over REXML?

This sounds great. Thanks for producing these bindings. I am really
glad to see this as it adds a simple interface for validating against
an xml schema.

Sadly I'll eventualy need to get this compiled on windows, which I've
never had much luck with ;)
