    <p>So using the advice found in my previous '<a href="https://stackoverflow.com/questions/8017667/using-nokogiri-to-search-through-xml-file-based-on-user-input-in-rails-app">question</a>', I have been able to get the results I want. </p> <p>I was wondering if anyone had an easy way to display these results in a Rails view that also has non XML content.</p> <p>I've looked into XSLT but don't know enough about it, especially not in relation to Rails, to know whether that is where I should spend my time. If so, I'd love some pointers on how I can use XSLT in Rails views.</p> <p>What I am looking for is to display a list of 'sdnEntry' results (see '<a href="http://www.treasury.gov/resource-center/sanctions/SDN-List/Documents/sdn.xsd" rel="nofollow noreferrer">XML Schema</a>' for details.)</p> <p>As you will see from the '<a href="http://www.treasury.gov/resource-center/sanctions/SDN-List/Documents/sdn.xsd" rel="nofollow noreferrer">XML Schema</a>', not all of the 'sdnEntry' items have the same elements. Therefore, I'd like to display the following information about each 'sdnEntry', omitting any empty elements where applicable.</p> <p>Please feel free to ask questions in comments. I really appreciate the help.</p> <p>EDIT #1: The XML file can be found <a href="http://www.treasury.gov/ofac/downloads/sdn.xml" rel="nofollow noreferrer">here</a>. (6MB)</p> <p>EDIT #2: I'd prefer something like a <code>&lt;dl&gt;/&lt;dt&gt;&lt;dd&gt;</code> list. Heck, I'd even settle for a plain old table. As for empty elements, you will see from the schema, that some child elements (like 'firstName' or 'address3', etc.) have 0 minimum occurrences, and are therefore not found for every 'sdnEntry'. If possible, I'd rather not show blank child elements. If that's a problem, I'd be fine with blanks in the end, if needed.</p> <p>EDIT #3: The results will always be a Nokogiri NodeSet of one or more 'sdnEntry' items. That's all I would need to display. I am confident that with enough guidance or example code, I could apply any provided solution to other needs down the line.</p>

    1. COWhen you say "display these results in a Rails view" do you mean that you want to display the raw XML in a 'pretty' format, like [this image](http://www.kirupa.com/net/images/xml_doc2.gif)? If so, is syntax coloring important? Or did you mean that you want to extract the information from the XML and display it in a pretty format (e.g. as a `<dl>/<dt><dd>` list custom labeled and formatted)? If so, did you need a generic solution (any XML snippet) or something tailored to the specific results you are getting?

    2. COI don't know what you mean in your next-to-last paragraph, _"I'd like to display the following information about each 'sdnEntry'"_. Did you intend to provide a list of specific elements you wanted to display? Or were you saying that even if there is no particular child element (e.g. if `<firstName>` is legally omitted) you still want to include an empty element in the output?

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
