    <p>I am aware of SO question <a href="https://stackoverflow.com/questions/9008864/java-read-xml-attributes">Failing to get element values using Element.getAttribute()</a> but because I am java begginer, I have additional questions. What I am trying to build is simple application, which will read XML file and then compare it against "golden master." My problem is:</p> <ul> <li>I have lots of different XML files, which differ in attributes</li> <li>The XML files are relatively big. (810 lines of filed - hard to check it by human eye)</li> </ul> <p>Example of file:</p> <pre><code> &lt;DocumentIdentification v="Unique_ID"/&gt; &lt;DocumentVersion v="1"/&gt; &lt;DocumentType v="P81"/&gt; &lt;SenderIdentification v="TEST-001--123456" codingScheme="A01"/&gt; &lt;CreationDateTime v="2012-10-15T13:00:00Z"/&gt; &lt;InArea v="10STS-TST------W" codingScheme="A01"/&gt; &lt;OutArea v="10YWT-AYXOP01--8" codingScheme="A01"/&gt; &lt;TimeSeries&gt; &lt;Period&gt; &lt;TimeInterval v="2012-10-14T22:00Z/2012-10-15T22:00Z"/&gt; &lt;Resolution v="PT15M"/&gt; &lt;Interval&gt; &lt;Pos v="1"/&gt; &lt;Qty v="500"/&gt; &lt;/Interval&gt; &lt;Interval&gt; &lt;Pos v="2"/&gt; &lt;Qty v="500"/&gt; &lt;/Interval&gt; &lt;Interval&gt; &lt;Pos v="3"/&gt; &lt;Qty v="452"/&gt; &lt;/Interval&gt; ... ... &lt;Interval&gt; &lt;Pos v="96"/&gt; &lt;Qty v="891"/&gt; &lt;/Interval&gt; &lt;/Period&gt; &lt;/TimeSeries&gt; </code></pre> <p>Applying solution from the question mentioned above does not get me much further... I realised that I can cast attributes to <code>NamedNodeMap</code> but I dont know how to iterate through it programatically</p> <p>Yes, I know it sounds much like "do my homework" but what I really need is at least small kick to butt, moving me in correct direction. Thanks for help</p>

    1. COwhat exactly is the goal of comparing the two files? you might get away by doing things way easier depending on what exactly you need to achieve.

    2. COMy idea is: Read the file and compare to expected values: Especially the bits with InArea and OutArea, SendersIdentification - those codes are specific to each file and should be unique to that name

    3. COin that case you are able to go with what Andreas_D somewhat suggests, the namedNodeMap can be obtained from doing node.getAttributes(), then using getNamedItem("v") to get the attribute

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.
