I'm trying yo access the customer Options within an asp.net web services application. I can't figure out how to go through the Item node set using an XPath expression to get all Items including the Customer Options nodeset. I want the PartNo, Description, UnitPrice,Quantity, TotalCost and then customeroptions if there is any for an item. The tricky part is I get an exception because obviously I end up eventually try storing data that isn't listed for customer options in to a struct I made. This is what I have in my function for web services.
[WebMethod]
public lab3 GetItemListForOrder(int OrderID)
{
string strFileName = Server.MapPath("~\\XML_OrderInfo_Lab3.xml");
XPathDocument xDoc = new XPathDocument(strFileName);
//XPathNodeIterator NodeIter;
XPathNavigator nav;
XPathNodeIterator NodeIter;
nav = xDoc.CreateNavigator();
string searchstring = "//OrderFeed/Order[ " + OrderID + "]/Items//Item";
NodeIter = nav.Select(searchstring);
StringBuilder sb = new StringBuilder();
while (NodeIter.MoveNext())
{
lab3 lab = new lab3();
XPathNavigator Items = NodeIter.Current;
lab.PartNO = Items.SelectSingleNode("PartNo").ToString();
lab.Description = Items.SelectSingleNode("Description").ToString();
lab.UnitPrice = Items.SelectSingleNode("UnitPrice").ToString();
lab.TotalCost = Items.SelectSingleNode("TotalCost").ToString();
lab.Size = Items.SelectSingleNode("Size").ToString();
sb.Append(Items.SelectSingleNode("Color").ToString() + Environment.NewLine);
return lab;
}
}
between the lab. TotalCost line and lab.Size, should be some kind of check to see if there is a customeroption available. I just can't figure it out and how to make it display correctly afterwards.
