Well, I feel a little bit annoyed about such recommendations like
"don't use what comes with ruby, get some much better stuff from xyz",
I'll expect ruby to come with working stuff.


The documentation of the libxml-ruby of current ubuntu (generated with
rdoc) is poor. Sometimes it referes to empty pages.

And something like

dc = xml.find("/document-content")

dc.each do |node|
puts "Node #{node}"
end



does not find anything either.

Ruby is a wonderful programming language, but should that not be a
reason not to have wonderful extensions and/or bindings.
It is completely normal that bindings to high class libraries as xml
will beat built in stuff like REXML.
I am sure that we all pointed out here is meaning if by any means
REXML does not do your job, no worries there are other solutions.
Maybe that was not clear.

So do I and AAMOF Ruby complies. And sorry for insisting but REXML is
not broken, just limited, mainly in performance.

If you provided the document one might be able to help.

I don't agree to that assessment of Michael. Whenever I have to deal
with XML in Ruby REXML is my first choice and it has worked out
remarkably well (if you ignore performance).

IIRC XPath notation this will only find element "document-content" at
root level. You probably rather want "//document-content".

I second Robert, please show the document and probably a bit more code.

Kind regards
