Hey All, While messing around with XML I became really frustrated at how unnatural it seemed to extract data out of documents. I ended up writing my own python class to do exactly what felt natural. The problem is the entire time I kept telling myself "this code has to already exist somewhere" I just could never find it. So if anyone is interested take a look at how this class works and tell me if 1) this seems useful 2) this is already supported by someone else A brief example of how it is used -------------- < collection > < comic issue="1"> < author > Stan Lee < /author > < /comic > < /collection > can be accessed as collection.comic.author.TEXT collection.comic.ATTR('issue') --------------- a more complete write-up w/source is available at http://www.people.hbs.edu/jgriffith/simplexmlobject.html Thanks! -Jeff Griffith

< collection > < comic issue="1"> < author > Stan Lee < /author > < /comic > < /collection >

collection.comic.author.TEXT collection.comic.ATTR('issue')
Nice idea, however what happens when you have multiple 'comic' tags at that point?

Perhaps you've addressed this shortcoming in your write up.. unfortunately, i don't have time to read it.. :(
Thanks! -Jeff Griffith
Have a better one, Curtis Maloney.

Re 2) I suspect something very similar you should look at is xml_objectify and xml_pickle explained in xml_matters_1.zip and 2.zip, all at: http://www.gnosis.cx/download/ via: http://gnosis.cx/publish/tech_index.html

Have you looked at ParsedXML? http://www.zope.org/Wikis/DevSite/Projects/ParsedXML/Releases It is a fully DOM level 2 compliant XML object. It'll let you access your XML via DOM calls. They may seem less convenient than your example, but will cover the cases where you have more than one 'comic' element. Your example could translate to: xmlDoc.documentElement.childNodes[0].childNodes[0].childNodes[0] xmlDoc.documentElement.childNodes[0].getAttribute('issue') or by using the tagname the first example would become: comic = xmlDoc.documentElement.getElementsByTagName('comic')[0] authorName = comic.getElementsByTagName('author')[0].getChildNodes(0) In future versions, XML id support is planned; if you have a DTD that tells the parser what attributes are Id's, you can traverse the tree using Id attributes for the same effect. Then you can use a document like: <collection> <comic issue="1" id="first_issue"> <author>Stan Lee</author> </comic> </collection> and code like: comic = xmlDoc.getElementById('first_issue') authorName = comic.getElementsByTagName('author')[0].getChildNodes(0) Hope this helps! -- Martijn Pieters | Software Engineer mailto:mj@digicool.com | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------
