Is there a way to organize/print out the xml attributes using Hpricot,
or do I have to run through the xml file again and replace patterns?
I would like to be able to say "put this attribute first, put this
attribute next ...", so I can say, I want this:
<node id="name" property="value"/>
not this:
<node property="value" id="name"/>
Since the attributes are kept in a hash there's no order to them, so
they appear in seemingly random order, but it's the same random order
consistently.
Any ideas how to do that?
And is there a way to say "after two attributes, make a new line". So I
can print out xml that can be edited by humans like code.

a Hash can be sorted to give an Array with Hash#sort :

This means though I have to do two passes on the XML:
1) Modify the nodes with data the way nokogiri or hpricot do it (xpath
and whatnot)
2) Format the xml using regular expression on pure strings, not using
the xml parsing engines.

Is that correct?
Lance,
I remember that Hpricot and Nokogiri both have pretty_print methods, but I have never used them. Also, I don't know whether "pretty" can be defined so that everybody agrees
I would not work on the output XML via String replacements. I would
rather adjust the output process. For example, if you would be
working with REXML you could implement a Formatter which outputs
attributes in a particular order. I don't know whether this can be
done with Nokogiri or Hpricot as well or as easily.
Kind regards

require 'rexml/document'
class OrderedAttributes < REXML::Formatters::Pretty
def write_element(elm, out)
att = elm.attributes
class <<att
alias _each_attribute each_attribute
def each_attribute(&b)
to_enum(:_each_attribute).sort_by {|x| x.name}.each(&b)
end
end
