Hello everyone. I have a problem using Linq To Xml.
A simple code. I have this XML:
<?xml version="1.0" encoding="utf-8" ?>
<data xmlns="http://www.xxx.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.xxx.com/directory file.xsd">
<contact>
<name>aaa</name>
<email>
[email protected]</email>
<birthdate>2002-09-22</birthdate>
<telephone>000:000000</telephone>
<description>Description for this contact</description>
</contact>
<contact>
<name>sss</name>
<email>
[email protected]</email>
<birthdate>2002-09-22</birthdate>
<telephone>000:000000</telephone>

<contact>
<name>bbb</name>
<email>
[email protected]</email>
<birthdate>2002-09-22</birthdate>
<telephone>000:000000</telephone>
<description>Description for this contact</description>

<contact>
<name>ccc</name>

<birthdate>2002-09-22</birthdate>
<telephone>000:000000</telephone>
<description>Description for this contact</description>
</contact>
I want to get every contact mapping it on an object Contact. To do this I use this fragment of code:
XDocument XDoc = XDocument.Load(System.Web.HttpRuntime.AppDomainAppPath + this.filesource);
XElement XRoot = XDoc.Root;
//XElement XEl = XElement.Load(this.filesource);
var results = from e in XRoot.Elements("contact")
select new Contact((string)e.Element("name"), (string)e.Element("email"), "1-1-1", null, null);
List<Contact> cntcts = new List<Contact>();
foreach (Contact cntct in results) {
cntcts.Add(cntct);
}
Contact[] c = cntcts.ToArray();
// Encapsulating element
Elements<Contact> final = new Elements<Contact>(c);
Ok just don't mind that all: focus on this:
When I get the root node, it is all right, I get it correctly.
When I use the select directive I try to get every node saying: from e in
XRoot.Elements("contact")
OK here's the problem: if I use: from e in XRoot.Elements() I get all contact nodes, but if I use: from e in XRoot.Elements("contact") I GET NOTHING: Empty SET.
OK you tell me: Use the other one:
OK I DO SO, let's use:
from e in XRoot.Elements(), I get all nodes anyway, THAT's RIGHT BUT HERE COMES THE OTHER PROBLEM:
When Saying: select new Contact((string)e.Element("name"), (string)e.Element("email"), "1-1-1", null, null); I Try to access <name>, <email>... I HAVE TO USE .Element("name") AND IT DOES NOT WORK TOO!!!!!!!!WHAT THE HELL IS THIS????????????? IT SEEMS THAT I DOES NOT MATCH THE NAME I PASS But how is it possible. I know that Elements() function takes, overloaded, one argument that is an XName which is mapped onto a string. Please consider that the code I wrote come from an example, It should work.
Please somebody help me.
THANKS IN ADVANCE
