    <p>I have to transform xml file where i should check field id '0', field id '1' and sum field id '2'. For example I have:</p> <pre><code>&lt;document&gt; &lt;line id="0"&gt; &lt;field id="0"&gt;MAR&lt;/field&gt; &lt;field id="1"&gt;doc1&lt;/field&gt; &lt;field id="2"&gt;2&lt;/field&gt; &lt;/line&gt; &lt;line id="1"&gt; &lt;field id="0"&gt;MAR&lt;/field&gt; &lt;field id="1"&gt;doc2&lt;/field&gt; &lt;field id="2"&gt;3&lt;/field&gt; &lt;/line&gt; &lt;line id="2"&gt; &lt;field id="0"&gt;AAA&gt;&lt;/field&gt; &lt;field id="1"&gt;doc4&lt;/field&gt; &lt;/line&gt; &lt;line id="3"&gt; &lt;field id="0"&gt;MAR&lt;/field&gt; &lt;field id="1"&gt;doc1&lt;/field&gt; &lt;field id="2"&gt;4&lt;/field&gt; &lt;/line&gt; &lt;/document&gt; </code></pre> <p>result should be:</p> <pre><code>&lt;type-MAR&gt; &lt;document&gt;doc1&lt;/document&gt; &lt;sum&gt;6&lt;/sum&gt; &lt;/type-MAR&gt; &lt;type-MAR&gt; &lt;document&gt;doc2&lt;/document&gt; &lt;sum&gt;3&lt;/sum&gt; &lt;/type-MAR&gt; </code></pre> <p>there I should take all MAR lines, and show some results which are depends of field id '1'.</p> <p>My idea was, first off all do cycle(for each) and use condition(when). Maybe somebody offer more omptimal decision.</p> <p>I add new note, how to check if data comes like that:</p> <pre><code>&lt;field id="0"&gt;MAR999&lt;/field&gt; &lt;field id="1"&gt;doc1-1231&lt;/field&gt; </code></pre> <p>First field i try to use function contains 'MAR', others substring-before '-'. but I stuck when I try it use on Yours program. maybe you can take some advice for it?</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.
