Hi!  
Is there a way to deal with XML-files in Ruby? And further: is there a  
(existing) solution/way how to parse/validate XML-files against a XML-  
Schema (XSD)?

Thanks for any help!  
Dominik A.

REXML is the Ruby Library for parsing xml docs. Not sure if it  
validates though.  
[http://www.germane-software.com/software/rexml/](http://www.germane-software.com/software/rexml/) has a tutorial and the  
documentation. The documentation is also available with the standard  
RDoc.

There is also libxml-ruby:  
[http://libxml.rubyforge.org/doc/](http://libxml.rubyforge.org/doc/)

Also, I have used JRuby to use Java XML processing libraries.

I finally found (after I googled “libxml-ruby xsd”) a “Recipe” how to  
validate XML-files against DTD/XSD!  
Here is the link:  
[http://codeidol.com/other/rubyckbk/XML-and-HTML/Validating-an-XML-Document/](http://codeidol.com/other/rubyckbk/XML-and-HTML/Validating-an-XML-Document/)  
I think it’s using “libxml-ruby”, but (as I understood it) it is not a  
“pure-Ruby”-solution because it’s using a C library. But that’s no  
problem.

Thanks for your hints!
