    <p>I am working on a JavaScript library that is supposed to be used by different applications targeting various platforms such as Web/iOS/Android. </p> <p>In this, the application would need to make REST-calls to retrieve and parse a large multilevel XML data(with namespace). Planning to use jQuery here.</p> <p>The large-XML can contain data that may not be useful at times. </p> <p>For example, depending on the Locale-setting in the application that uses this library, only a subset of a meta-data need to be parsed.</p> <pre><code> &lt;meta&gt; &lt;data&gt; ... ... ... &lt;/data&gt; &lt;component local="EN-US"&gt; ... &lt;/component&gt; &lt;component local="EN-UK"&gt; ... &lt;/component&gt; &lt;component local="EN-AU"&gt; ... &lt;/component&gt; &lt;/meta&gt; </code></pre> <p>So, parsing all the data received in the Ajax-response seems to be a waste of effort.</p> <p>Keeping this in mind, I wonder if the following is a good way to approach this problem: 1. Store the "responseXML" received in the JQuery's Ajax success callback. 2. When the application requests the data for say "EN-US", parse the appropriate sub-nodes from the stored "responseXML" document, and return the result. (If the user changes the Locale-setting, no problem, we can go and parse the appropriate section of the XML-Data).</p> <p>I do understand that, parsing on the go will add a delay to the application, but it seems to me that, overall application performance will be better. No need to parse all the data upfront and use only portion of it.</p> <p>Please share your thoughts/ideas.</p> <p><strong>EDIT:</strong> Server is controlled by a different team with different priorities. So, changing the server-side code to return appropriate data is not an option at the moment. </p> <p>Thanks in Advance,</p>

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.
