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.

Ehm tena sakai,
how do you charge the details?
maybe you can give me a tipp or tell me how do you charge it?
