I want to sort a XML-Document by attributes of an Child-Node. I am working with Windows Forms in Visual C++. I tried to use the solution proposed <a href="https://stackoverflow.com/questions/344737/sorting-xml-nodes-based-on-datetime-attribute-c-xpath">here on Stackoverflow</a>. But somehow it won't work. My unsorted XML-Doc looks like the following: <pre class="lang-xml prettyprint-override"><code><Message-List> <Message sendTime="0"></Message> <Message sendTime="20"></Message> <Message sendTime="5"></Message> </Message-List> </code></pre> My sorted XML-Doc should look like this: <pre class="lang-xml prettyprint-override"><code><Message-List> <Message sendTime="0"></Message> <Message sendTime="5"></Message> <Message sendTime="20"></Message> </Message-List> </code></pre> I tried following Code, but the checkme-String returned is 0205. So the sorting doesn't even work. <pre class="lang-cpp prettyprint-override"><code>System::Xml::XmlDocument^ sourceXmlDoc = gcnew XmlDocument; sourceXmlDoc->LoadXml("<Message-List><Message sendTime=\"0\"></Message><Message sendTime=\"20\"></Message><Message sendTime=\"5\"></Message></Message-List>"); System::Xml::XPath::XPathNavigator^ navigator = sourceXmlDoc->CreateNavigator(); System::Xml::XPath::XPathExpression^ selectExpression = navigator->Compile("Message-List/Message"); System::Xml::XPath::XPathExpression^ sortExpr = navigator->Compile("@sendTime"); selectExpression->AddSort(sortExpr, XmlSortOrder::Ascending, XmlCaseOrder::None, "", XmlDataType::Text); System::Xml::XPath::XPathNodeIterator^ nodeIterator = navigator->Select(selectExpression); String^ checkMe; while (nodeIterator->MoveNext()) { if (nodeIterator->Current->MoveToFirstAttribute()) { checkMe = checkMe + nodeIterator->Current->Value; } } </code></pre> Furthermore, I am stuck on how to proceed in the while-loop. How can I save the resorted xmlDoc as XmlDocument?

Guidance

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.
