Hi folks,

I am still on page 21. I typed a few lines into a file named example.xml, which looks like:

<?xml version='1.0' encoding='UTF-8'?>
<ListAllMyBucketsResult xmlns='http://s3.amazon.com/doc/2006-03-01/'>
<Owner>
<ID>1a2b3c4d5e6f1a2b3c4d5e6f1a2b3c4d5e6f1a2b3c4d5e6f1a2b3c4d5e6f1a2b</ID>

<CreationDate>2007-09-24T08:39:30.000Z</CreationDate>
</Bucket>
</Buckets>
</ListAllMyBucketsResult>


Then I typed a few lines like:

[tsakai]$ irb
irb(main):001:0> xml_text = File.new('example.xml','r').read
=> "<?xml version='1.0' encoding='UTF-8'?>\n<ListAllMyBucketsResult xmlns='http://s3.amazon.com/doc/2006-03-01/'>\n <Owner>\n <ID>1a2b3c4d5e6f1a2b3c4d5e6f1a2b3c4d5e6f1a2b3c4d5e6f1a2b3c4d5e6f1a2b</ID>\n <DisplayName>jamesmurty</DisplayName>\n </Owner>\n <Buckets>\n <Bucket>\n <Name>oreilly-aws</Name>\n <CreationDate>2007-09-24T08:20:49.000Z</CreationDate>\n </Bucket>\n <Bucket>\n <Name>my-bucket</Name>\n <CreationDate>2007-09-24T08:39:30.000Z</CreationDate>\n </Bucket>\n </Buckets>\n</ListAllMyBucketsResult>\n"
irb(main):002:0> require 'rexml/document'
=> true
irb(main):003:0> xml_doc = REXML::Document.new(xml_text)
=> <UNDEFINED> ... </>
irb(main):004:0>

What I don't understand is the response from my last line:
<UNDEFINED> ... </>

Can someone please tell me what this means?

Don't get too bogged down in the details. The main point of this section of the book is to demonstrate very quickly how XPATH queries can be used to search XML documents.

If you continue on, you will find that the sample works as expected.

The topic of XML document processing is a big one, and it isn't really addressed in any detail in this book

Thank you, James. It is a habit of mine that I get caught in details. I will charge on.

The Amazon Web Services (AWS) are a collection of remote computing services (also called web services) offered over the Internet by Amazon.com.

Launched in July 2002, Amazon Web Services provide online services for other web sites or client-side applications. Most of these services are not exposed directly to end users, but instead offer functionality that other developers can use. In June 2007, Amazon claimed that more than 330,000 developers had signed up to use Amazon Web Services.[1]

Amazon Web Services’ offerings are accessed over HTTP, using REST and SOAP protocols. All are billed on usage, with the exact form of usage varying from service to service.
