i tried all this variations b4 i post this problem, but i'd like to ask somthin, why its tricky ? no standard ? thanx for reply :)

Its tricky for me as I rarely use it, and tend to forget the exactly syntax. XPath is simply Regular Expressions for XML. The is a complete standard for it. .NET supports version 1.1 I think. The easiest way to test things is just to start with "*" and continue up to "*/*/*" and see what is really being matched, from there is should be easy, except if you are using XmlNamespaces (which u are not). Your problem looks like a context problem, iow you are starting at the wrong node, like I mentioned in my previous post. top secret

Why do you have the in you xml file? Check if xElement is empty I use something like this and see if sId has some value XmlNode node; node = xml.FirstChild; while (node.Name != "Ticket" & !(node == null)) { node = node.NextSibling; } string sId; sId = node.Attributes("id").Value;

while (node.Name != "Question" & !(node == null)) { node = node.NextSibling; }

This type of code is exactly what XPath prevents you from having to do :p top secret

The XPath is fine, that is not where your problem lies. I just made your XML valid and tested it. If I have trouble with an XPath, I use XSLerator or something similar to test it, and build it one step at a time.

i think i caught where the problem lies, the problem is me, damn, sorry guys, i didn't paste the exactly code as in my project , its my first time using xml so don't blame me, i think i'm using a namespace, and heres my exactly xml file

i didn't think that will be a diffrent while using namespace, so now, what should i change in my C# code to let XPath work ? sorry guys again and thanx :)

[Ahmed Galal]

the file may be large and that way may take a long time to select the node i need, do u think that XPath using this way to select nodes ? i dunno

If speed becomes an issue, look into storing the data in database. top secret
