Hi Everyone,
I´m trying to develop a control for display XmlNodes. the attributes of the actual node and his leave-nodes (<a>DATA</a>) will be display in textboxes, so that the user can change them. All other child-nodes (with more children or attributes) should be displayed as linkbuttons. So far so good. But when am trying to compute the actual XmlNode a got some problems. Most of the time my code works fine, but when there is some special kind of xmlcode I get an Exception. I-man have located the problem. Sometimes myXmlNode.attributes.Count is null! Does anyone know a solution?
Here is the "sinister" XmlCode:
<Person groesse="20" gewicht="90" >
<Nachname geschlecht="Mann">Arnold</Nachname>
<Vorname>Schwarz</Vorname>
<Hobbys>
<Hobby>Capoeira</Hobby>
<Hobby>Musik</Hobby>
</Hobbys>
<Alter>54</Alter>
<sport />
</Person>
Here is my method:
public void ShowXmlNode(XmlNode myXmlNode)
{
// Set the Attributes
this.NodeAttributes = GetAttributes(myXmlNode);
// Create the ArrayLists which will later catain the leaves / children
ArrayList myChildren =new ArrayList();
ArrayList myLeaves = new ArrayList();
XmlNodeList myChildNodes = myXmlNode.ChildNodes;
foreach (XmlNode myWorkerNode in myChildNodes)
{
if (myWorkerNode.ChildNodes.Count > 1 || myWorkerNode.Attributes.Count >0) myChildren.Add(myWorkerNode.Name.ToString());
else
// No Attributes, No Children => Leave
myLeaves.Add(new Pair(myWorkerNode.Name, myWorkerNode.InnerText));
}
this.Leaves = myLeaves;
this.Children = myChildren;
}
The porblem occurs, when the node passed to the method, is this part of the xmldocument:
<Nachname geschlecht="Mann">Arnold</Nachname>
The Exception is thrown at :
... myWorkerNode.Attributes.Count >0)
Thanks
Klaus
