Did you try? 
As quick look at MSDN shows it (System.Array) has [Serializable] attribute, so I guess answer is YES.

Here's my code:
try
{
_strContent = "<Employees><Employee id=\"1\"><Name>Ethan</Name></Employee></Employees>"
_xmlDoc.Load(".\\EMP.xml");
_docFrag = _xmlDoc.CreateDocumentFragment();
_docFrag.InnerXml = _strContent;
_xmlDoc.DocumentElement.AppendChild(_docFrag);
_xmlDoc.Save(".\\EMP.xml");
}
catch(Exception exc)
{
MessageBox.Show(exc.ToString());
}
The EMP.xml is already existing. I just used the above block of code to add new nodes into an existing EMP.xml file. But, I received this exception:
This is an unexpected token. The expected token is 'EndElement'
Unlikely though, the code performs its function. When I check the file, I saw that the node I am trying to add was there, its just that the error keeps on prompting. Will anyone help me? Thanks in advance!

well I don't know what exactly is problem there, maybe you already solved it (?).

That means syntax error in your XML. Surprisingly.

Strange.
Could you post small examples of input/output? Or at least where exactly exception raises? I mean what statement? _xmlDoc.Load(), _xmlDoc.Save(), AppendChild?
Funny how can be debugging something about 10 lines difficult. I just failed test cuz of the same

How could i convert XML file to STRING?
Here's my sample file...
Books.xml
<Books>
<Book>
<Title>Angels and Demons</Title>
<Author>Dan Brown</Author>
</Book>
</Books>

hmmm. Could you delete your next "posts"? I mean you should MODIFY this one, not to post it again. If you didn't notice, there is magical "modify" link that allows you to edit your post. "delete" is right next to it  Thank you.
As for your question... How do you want output to look like? If you have XML file and you want to have string with ALL markup, simple solution is to load it with System.IO.TextReader.
If you want to get only "Dan Brown", you should use classes from System.XmlNamespace. You can use XmlTextReader (similar way as TextReader, bt it reads XML nodes not characters or lines like TextReader) or XmlDocument (easy - it has Load(filename) method). To get "Dan Brown" text, you have to read <Author> element - with XmlTextReader use
this link cuz I just realized that I have lot of work now... sorry[^]

Hi David, thanks for your help, I think i'll prefer the use of TextReader.

I am not a C# person nor am I a XML person.
But I have enough skills I can fake it. Could you suggest a C# book that has a basic
1. Read an XML file
2. Determine that it is well formated.
3. Validate the scheme.
4. Write the result.
thanks

hi,
first could you please edit your post and check "Do not thread <'s as HTML tags"?
Sylesh wrote:

Does it mean you get empty NodeList? According to MSDN docs[^] you don't have to (or maybe you CAN'T) include whole path as argument.
Simple
XmlNodeList _NodeList = _Document.GetElementsByTagName("myListGrid");<br />
should be enough.
Sylesh wrote:
List.Add(_Node.Attributes.GetNamedItem ("value").InnerText);
Or does it fail there?

I take in a xsl file the data from a xml file: <xsl:value-of select="name">. How do i do so that the "name" apears as a link to "name". (for ex.:if name is "www.codeproject.com" the i want ro appear as a link to it's own text).
Thanks!
|
|
|
|

oh I don't undestand what is your goal. Plz try to edit your post (modify) so we can see <xsl:value-of select="name"> - I don't think everybody looks at source code to see what you indended to write - you have to check "do not treat..." or escape all < and >.
Do you have XML like <name>www.codeproject</name> and you want to do what with it? transfrom it to hyperlink?
One way is:
<br />
<a><br />
<xsl:attribute name="href"><br />
<xsl:value-of select="name" /><br />
</xsl:attribute><br />
<xsl:value-of select="name" /><br />
</a><br />
Or do you want something else?

ok,
first, do you know that you can edit your (non-anonymous) post? There is no need to post it again.
and second, if I understand correctly that problem is with editing some (configuration?) file - portal.xml, so you should seek help at DiGIR website...

Hello,
I am trying to create a webservice that will enable me to retrieve rows from a database in sql. I would like the service to return the datatable filled with the records. So that the consumer can display in a datagrid. But l am not sure if l am going about it correctly.
This is my code below.
[WebMethod (Description="This will get retrieve customers' orders")]<br />
public DataTable RetrieveOrders()<br />
{<br />
SqlConnection cnn = new SqlConnection("Server = Steves-pc; Database = northwind; Integrated Security = yes");<br />
cnn.Open();<br />
SqlDataAdapter da = new SqlDataAdapter();<br />
SqlCommand cmd = new SqlCommand();<br />
DataTable dt = new DataTable("Orders");<br />
<br />
string getOrders = "SELECT OrderID,CustomerID,ShipName,ShipCountry FROM Orders";<br />
cmd = cnn.CreateCommand();<br />
cmd.CommandType = CommandType.Text;<br />
cmd.CommandText = getOrders;<br />
da.SelectCommand = cmd;<br />
<br />
dt.Clear();<br />
da.Fill(dt);<br />
<br />
cnn.Close();<br />
<br />
return dt; <br />
}
Many thanks in advance,
Steve

Here's a quick code diagnosis:
steve_rm wrote:
cnn.Open();
This line is not needed since you are using an SqlDataAdapter. The SqlDataAdapter automatically calls the SqlConnection.Open() and SqlConnection.Close() methods.
steve_rm wrote:
SqlCommand cmd = new SqlCommand();
You don't need to initialize this variable since you are re-assigning it later in your code:
steve_rm wrote:
cmd = cnn.CreateCommand();
You should set SqlCommand cmd = null;.
This call is not needed since the DataTable is empty after creation:
steve_rm wrote:
dt.Clear();
As previously stated, this line is not needed (see above).
steve_rm wrote:
cnn.Close();
Hope this helps!
