Hey Charlie, what great news you give us!

Great work all the guys involved, now and the past on this project.

For the libxml2.dll requirement maybe we can build libxml statically instead, but I think the next step is worthy.

Again, great work!

Hi Luis,

I just read an interview with your earlier this year on Akita on Rails. Great work on the one-click installer. Ping me at my email (its on the about page) if you’d like to talk about it a bit more, I’ve gotten pretty good and this MSVC/MingW Windows Ruby stuff after doing it for a couple of years now.

Hi Luis,

About the libxml2.dll. It would be great if libxml-ruby could come in the one-click installer, and in that case, I’d put the dll into the Ruby bin directory like is done for other libraries. And if we’re doing that, how about adding libxslt-ruby also?

Hey Charlie,

Current VC6 One-Click Installer is a huge monolithic script and is kind of hard to maintain and test everything that is been bundled there.

We are working on the new rubyinstaller sandbox and build environment that uses Windows Installer and provide a smaller runtime (Ruby+RubyGems) to get you started and a Developer Kit (MinGW+MSYS) to build those gems that don’t come pre-built for Windows.

I’ve been thinking fix the binary files bundling of rubygems to allow .dll files be part of gems…

I’ll get in touch with you soon about libxml :-) (in any case, I invite you to rubyinstaller-devel mailing list):

Thanks again for your kind words!

I’d like to talk to you about possibly building a Java backend for the libxml library. Since so many people seem to be interested in a good XML library these days, and since XML libraries by and large look pretty much the same on the surface, I’m pretty sure we could map the libxml APIs onto JAXP for JRuby. That would allow people even more confidence to move to libxml for all XML purposes, since they wouldn’t be tied to the C impls. So hey, drop me a line or find me on FreeNode @ #jruby.

On Windows, you mentioned the extra step of copying the prebuilt libxml2.dll. Is there any place from where I can copy the prebuilt dll or I would need to build it?

Rajmohan,

A prebuilt libxml2.dll is already in the libxml/mingw directory. If you already have libxml installed on your system, you won’t have to do anything. If you don’t, then copy the dll to your ruby/bin directory or somewhere on your Windows path.

Also, I’ve updated the post to be a bit more clear on how to get things up and running on Windows.

Awesome work!! Anyone knows if this is “plug and play” for Rails or does it need adapting? For ActiveResource based apps this could mean a significant performance boost! Congrats!

First off, great work and thanks for taking up libxml-ruby.

Even after changing the search path to something that exists in the document I’m parsing, this example still doesn’t seem to work for me:

` doc.find(‘//root_node/foo/bar’).each do |node|

puts "Node path: #{node.path} \t Contents: #{node.content}"

end`

In fact, I can’t seem to get anything related to .find to work at all (.empty? always returns true). Got any suggestions?

http://saxon.sourceforge.net/saxon6.5.3/expressions.html

More specifically, if you look at the table at the bottom of that page, I can get things like ’’ and ’[last()]’ to work, but anything involving a literal string like ‘XXX’ or ‘//XXX’ will return a nil NodeSet.

Hi Dan,

Best to post issues to the libxml ruby forge tracker - better chance of getting a response.

My guess is your document has a default namespace (). In that case, refer to these Rdocs:

http://libxml.rubyforge.org/rdoc/classes/LibXML/XML/XPath.html

Aha. I figured the problem was most likely user error and not a bug, but I had no idea why. You were right about the namespace thing.

This link also helped solve my issue:

Currently I’am using REXML and ruby-xsl for a project, the code is ugly and slow. I’m going to rewrite the code to come back to libxml-ruby. Great work !

Comment on Resurrecting libxml-ruby by Charlie

Sounds good Alex. If you feel like doing the intermediate step, writing a wrapper for libxml with the same api as REXML, then do submit it to the libxml project and we’ll include it in the distribution (as long as it passes all REXML tests).

I am getting segmentation faults on 64-bit redhat fairly randomly and faily regularly while doing a large amount of data importing. I was using 0.5.4 and never once had a seg.fault. After upgrading, I am getting them alot. Any idea if seg. faults are an issue with 64-bit right now? I am currently versioning down to see if I can determine if this is truly related to the upgrade.

Hi Kurt,

Could you post to the libxml-devel mailing list, where we can try and work out the issue. Any additional information would be helpful - example XML file, example code, and best yet a stack trace, etc.

Hi,

First all : great work => the code is much much faster than with REXML…

I’m working on Windows system, and I have an error : “[BUG] Segmentation fault ruby 1.8.6 (2007-03-13) [i386-mswin32]”

I’ve found a discussion at http://www.mail-archive.com/libxml-devel@rubyforge.org/msg01049.html which gives a patch.

But, I don’t know how to apply this patch (http://www.acidlunchbox.com/bagby/ref_count.diff )…

Anyone can help me please ?
