Formatting REXML

Ruby
1

Hey all,

I posted a question on StackOverflow the other day that I thought would
be reasonably easy to answer, but actually, I got nothin’, zilch, nada.
Rather than repeat the question here, here’s the link:

http://bit.ly/tN7FK

I don’t mind if there’s a way of formatting the XML with something other
than REXML - whatever achieves the result is good with me. Any help
would be really welcome as I’ve spend ages now trying to do this one
stupid thing.

Many thanks,
Charles

Hi Robert, thanks for the link. I have already spent quite some time
looking over these formatters and I just can’t seem to get the
formatting I want. It’s probably me being stupid, but I can’t see how to
get the result I want.

I want the last 3 lines to look like this:

gutter
#282828

But I can only get this:

gutter#282828

or this:

gutter #282828

Many thanks.

Bte, your XML is invalid. The opening tag is missing.

And, apparently you did not read the docs properly:

irb(main):143:0> d = REXML::Document.new
“gutter#282828”
=> … </>
irb(main):144:0> f=REXML::Formatters::Pretty.new
=> #<REXML::Formatters::Pretty:0x1037b030 @indentation=2, @level=0,
@ie_hack=false, @width=80, @compact=false>
irb(main):145:0> f.compact=true
=> true
irb(main):146:0> puts f.write(d.root,“”)

gutter
#282828

=> nil
irb(main):147:0>

Cheers

FTFY

require ‘rubygems’
require ‘nokogiri’

doc = Nokogiri::XML(DATA.read) { |cfg| cfg.noblanks }

Nokogiri::XML::Builder.new do |xml|
xml.doc = doc
xml.parent = doc.at(‘dict’)

xml.key(‘gutter’)
xml.string(‘#282828’)
end

puts doc.to_xml

END

background
#FFFFFF
caret
#000000
foreground
#000000
invisibles
#BFBFBF
lineHighlight
#00000012
selection
#BAD6FD

Doesn’t use REXML, but does output the formatting you want. Hope that
helps!

Nokogiri looks super-nice. Much simpler than REXML from an initial
glance. I’m going to have a play with it shortly. Already loving the
CSS3 selectors which, for me, coming from a design background, are so
much easier to grok than XPath. Although having said that, I was kind of
getting into XPath since I started playing around with REXML. Cool how
you can mix-and-match in Nokigiri.

Thanks for the head-up!

Cheers,
Charles

Yeah, sorry, I didn’t give terribly clear background infomation. That
XML I posted was just a snippet from a full XML document. Example:

http://pastie.org/619068

I didn’t paste the whole thing because I didn’t want to clutter the post
too much. Sorry for not explaining that more clearly. :slight_smile:

irb(main):146:0> puts f.write(d.root,“”)

Awesome, this gave me the clue I needed. I was doing this:

puts out.write(tmtheme,“”)

Whereas I needed to do this:

puts out.write(tmtheme.root,“”)

Bingo! Thanks for your help Robert, it is very much appreciated.

Cheers,
Charles
