Ordering XML Attributes with Hpricot?
in [Ruby]

From: Lance Pollard on 24 Sep 2009 17:08 Hey, 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. Thanks, Lance -- Posted via http://www.ruby-forum.com/.

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? Thanks, Lance -- Posted via http://www.ruby-forum.com/. |
