Question

I am currently working on a .net C# solution that returns 2 sibling nodes. Using Xpath 1.0

A small example of my xml doc is this:

<PLAY>
 <SCENE>
  <SPEAKER>
  </SPEAKER>
  <LINE>
  </LINE>
  </SCENE>
</PLAY>

I am using the following code to get the line and the speaker but i dont know why i get the entire xml doc being passed in instead of just the sibling (speaker)

I have :

List speakers = new List();

XmlDocument myDoc = new XmlDocument();
myDoc.Load(textXMLFile.Text.ToString());
// Clear the text box...
textResults.Text = "";

// ADD THIS...
XPathNavigator theNav = myDoc.CreateNavigator();
XPathNavigator theNav2 = myDoc.CreateNavigator();

//XmlNodeList theNodes =
//    myDoc.SelectNodes(textXPath.Text.ToString());

textXPath.Text = "//SPEECH/LINE";
string val = "//SPEECH/SPEAKER";
XPathNodeIterator theNodes = theNav.Select(textXPath.Text.ToString());
XPathNodeIterator theNodes2 = theNav2.Select(val);

StringBuilder output = new StringBuilder();

while (theNodes.MoveNext())
{
    if (theNodes.Current.InnerXml.ToString() == "Upon my sword.")
    {
        break;
    }
    else
    {
        speakers.Add(theNodes2.Current.InnerXml.ToString());
        speakers.Add(theNodes2.Current.InnerXml.ToString());
    }
}
for (int i =0; i < speakers.Count; ++i)
{
    output.Append (speakers[i]+" ");
}
MessageBox.Show(""+output);

theNodes.Current.InnerXml.ToString() works fine for returning the line but theNodes2.Current.InnerXml.ToString() seems to return the entire XML instead of the speaker.

Any comments or suggestions are appreciated.

After staring at this for awhile i totally missed that i needed to move theNodes2 also in the while loop like so


while(theNodes2.MoveNext())


Thanks All
