    <p>I recently reviewed a bunch of XML libraries specifically for generating XML code. </p> <p>Executive summary: I chose to go with <a href="http://code.google.com/p/ticpp/" rel="nofollow noreferrer">TinyXML++</a>. </p> <p>TinyXML++ has decent C++ syntax, is built on the mature <a href="http://www.grinninglizard.com/tinyxml/" rel="nofollow noreferrer">TinyXML</a> C libraries, is free &amp; open source (MIT license) and small. In short, it helps get the job done quickly. Here's a quick snippet:</p> <pre><code>Document doc; Node* root(doc.InsertEndChild(Element("RootNode"))); Element measurements("measurements"); Element tbr("TotalBytesReceived", 12); measurements.InsertEndChild(tbr); root-&gt;InsertEndChild(measurements); </code></pre> <p>Which produces:</p> <pre><code>&lt;RootNode&gt; &lt;measurements&gt; &lt;TotalBytesReceived&gt;12&lt;/TotalBytesReceived&gt; &lt;/measurements&gt; &lt;/RootNode&gt; </code></pre> <p>I've been quite happy with it.</p> <p>I reviewed many others; here's some of the better contenders:</p> <p><a href="http://xerces.apache.org/xerces-c/" rel="nofollow noreferrer">Xerces</a>: The king-daddy. Does <em>everything</em> (especially when combined with <a href="http://xml.apache.org/xalan-c/" rel="nofollow noreferrer">Xalan</a>) but is heavyweight and forces memory management onto the user. </p> <p><a href="http://rapidxml.sourceforge.net/" rel="nofollow noreferrer">RapidXML</a>: Great for parsing (it's an in-situ parser and is <em>fast</em>) but not good for generation since adding nodes to the DOM requires memory management.</p> <p><a href="https://svn.boost.org/svn/boost/sandbox/xml/" rel="nofollow noreferrer">Boost.XML</a> (proposal): Looks <em>great</em> - powerful, excellent C++ syntax. However it hasn't yet gone through the review process, is unsupported and the interface may well change. Almost used it anyway. Looking forward to it's acceptance into Boost.</p> <p><a href="http://xmlsoft.org/" rel="nofollow noreferrer">Libxml</a>(<a href="http://libxmlplusplus.sourceforge.net/" rel="nofollow noreferrer">++</a>): Very good; powerful, decent syntax. But it's large-ish if all you're doing is <em>generating</em> XML and is tied to the glibmm library (for ustring). If we were <em>only</em> on Linux (like yourself?) I would seriously consider.</p> <p><a href="http://ximol.sourceforge.net/" rel="nofollow noreferrer">XiMOL</a>: Unique stream-based library. This was a little too simplistic for our needs but for basic XML generation you may find it quite useful. The stream syntax is quite neat.</p> <p>Hopefully there's something in there of some use!</p>

    1. COLooking at the TinyXML++ issues page, it appears that it has some memory leaks. Have you experienced that?

    3. COHm, looking at the innermost element I doubt that the output and the code match. :-)

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.
