Hi. I''m working with XML and REXML and I could use some help in two
particular issues:
First, I want to display a REXML::Document object. I''m creating the
object from a string that contains a valid xml, something like:
<company>
<name>Gecamin</name>
<address>Paseo Bulnes 197</address>
<employees>
<employee>
<first-name>Fernando</first-name>
<last-name>Poblete</last-name>
</employee>
<employee>
.....
</employee>
</employees>
</company>
And I want to produce HTML as follows:
<div class=''company''>
<p>Name: Gecamin</p>
<p>Address: Paseo Bulnes 197</p>
<div class=''employees''>
Employees
<div class=''employee''>
<p>First Name: Fernando</p>
<p>Last Name: Poblete</p>
....
...
The second thing is that I''m working with two versions of a same
record,
each one in a different REXML::Document object. So I have
@old_record_xml and @new_record_xml and want to compare them in order to
indicate which fields has changed from old version to new version. So if
an employee''s first name has been changedn I want to produce HTML like
<p class=''updated''>First Name: Fer</p>
I know XPath is the best answer but I haven''t been able to figure it
out. Could anyone give me some tips? Thanks.

For your first problem, it sounds like you should be using XSLT: greg.rubyfr.net/pub/packages/ruby-xslt/files/README.html For your second, I''ve never heard of XPath being used for this, but I could be wrong. It sounds like you''ll just have to write your own compare function that will emit nodes that have changed. On May 5, 12:41 am, Fernando Poblete <rails-mailing-l...@andreas- s.net> wrote:> Hi.

You need to get either msxsl.exe by Microsoft or xsltproc by everyone else. Then pipe your XML thru an XSLT template to re-render everything in XHTML. Below my sig is a snip of code that detects which one you have and calls it correctly. To diff XML, you could google for "diff XML", "XMLunit", or "XSLTunit". I have not tried either, but as diffing content is a major aspect of testing, the XSLTunit ought to show how to do it. -- Phlip oreilly.com/catalog/9780596510657 "Test Driven Ajax (on Rails)" assert_xpath, assert_javascript, & assert_ajax $win32Exts = %w{.exe .com .bat} # Adapted from Michael Granger''s FileWhich on RubyGarden def which(prog, path=ENV[''PATH'']) path.split(File::PATH_SEPARATOR).each {|dir| # Windows checks against specific extensions if File::ALT_SEPARATOR ext = $win32Exts.find{|ext| if prog.include?(''.'') # Assume extension already included f = File.join(dir,prog) else f = File.join(dir,prog+ext) end File.executable?(f) && !File.directory?(f) } if ext # Use backslashes, not forward slashes if prog.include?(''.'') # Assume extension already included f = File.join( dir, prog ).gsub(/\//,''\\'') else f = File.join( dir, prog + ext ).gsub(/\//,''\\'') end return f end else f = File.join(dir,prog) # Avoid /usr/lib/ruby, for example if File.executable?(f) && !File.directory?(f) return File::join( dir, prog ) end end } nil end def callXsl(xslFile, xmlFile, param = {}) msxsl = which(''msxsl'') xsltproc = which(''xsltproc'') if xsltproc != nil then params = '''' param.each { |p,v| params += "--param #{p} \"''#{v}''\" " } xhtml = `#{xsltproc} #{params} #{xslFile} #{xmlFile} 2>&1` return xhtml elsif msxsl != nil then params = '''' param.each { |p,v| params += p params += ''="'' params += v params += ''" '' } msxsl.gsub!''\\\\'', ''/'' cmd = "#{msxsl} #{xmlFile} #{xslFile} #{params}" xhtml = `#{cmd} 2>&1` return xhtml else return ''please install either msxsl or xsltproc'' end end def _Transform(xmlFile, xslFile, param) return callXsl(xslFile, xmlFile, param = {}) end --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
