Someone correct me if I'm wrong, but I don't think this can be done with a single XPath expression. The concat function returns a single text result, not a list. I suggest you run multiple XPath expressions and construct your results from that, or run a single XPath expression to get the <code>settings</code> elements you need, then take the <code>description</code> attribute from it and concatenate it with the <code>xml:id</code> attribute from the parent element if that's a <code>control</code> one. Nodes keep references to their parents. Use method <code>getParentNode()</code> to obtain it. Here's an alternative: run this XPath expression... <pre><code>//control[settings[@description!='-']]/@xml:id | //control/settings[@description!='-']/@description </code></pre> ... and then concatenate the text of the alternating results in the returned node list. In other words, text from item 0 + item 1, text from item 2 + item 3 etc. The above XPath expression will return this node list: <pre><code>0_0 text 1 0_1 text 2 1_0 text 3 1_1 text 4 </code></pre> You can then parse through that list and construct your results. Be careful. This will only work if there's at most 1 <code>settings</code> element per <code>control</code> element. Also, you may find that on evaluation the XPath engine throws an error for that <code>xml:</code> prefix. It may say that it's unknown. You might have to bind that prefix to the correct namespace first. Since the <code>xml</code> prefix is reserved and bound by default to a specific namespace, this might not be needed. I'm not certain as I haven't used it before. I've tested the expression in XMLSpy. It's not entirely impossible that the XPath engine used in Java (or the one you set for use) returns the nodes in another order. It might evaluate both parts of the "or" (the pipe symbol) separately and then dump the results into a single node list. I don't know what the XPath spec mandates regarding result ordering.

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.
