Do you know what a DTD is, and why do you need to use one? If you have the answers to these questions, you should know what to do.

hi all
This is to read the tag line by line.
using System.Xml;
...
...
...
XmlTextReader reader = new XmlTextReader ("reader.xml");
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Element: // The node is an element.
Console.Write("<" + reader.Name);
Console.WriteLine(">");
break;
case XmlNodeType.Text: //Display the text in each element.
Console.WriteLine (reader.Value);
break;
case XmlNodeType.EndElement: //Display the end of the element.
Console.Write("</" + reader.Name);
Console.WriteLine(">");
break;
}
}
Console.ReadLine();
How do i read the specific tag
if i just want to read all the tag that have this < big > tag?
thank you

This might help you get started:
reader.ReadToFollowing("big");
do
{
} while (reader.ReadToNextSibling("big"));

You can use XPath to simplify your work. For example:
XmlDataDocument xmlDoc = new XmlDataDocument();
xmlDoc.Load("yourfile.xml");
XmlNodeList xmlNodeList = xmlDoc.SelectNodes("roottag/big"); //XPath expression
More detail information pls. refer to Microsoft MSDN.

Unfortunately, our poster is using XmlTextReader. You don't use XPath with that.

Hi all,
Can you please let me know how to change the following XML so that i have HOME and SERVICES as parent node.At the moment HOME Contains SERVICES as a Sub Node.
What i want is When i click on Home the Service Link shouldnt be hidden.
<?xml version="1.0" encoding="utf-8" ?>
<siteMap>
<siteMapNode title="Home" >
<siteMapNode title="Services" >
<siteMapNode title="Training" url="~/Training.aspx"/>
</siteMapNode>

I don't know if anyone will understand your post, I know I don't. XML is text so when you click on it nothing is going to happen.
My guess is you left some stuff out of your post under the mistaken notion that we already know what you are thinking and doing, we don't, that's not really how internet forums work. Or perhaps you don't know anything about XML yourself. If that is the case try some of the tutorials at www.w3schools.com

I'm using an XMLDataSource to pull rss feeds into my site. Some of the feeds have really long descriptions, so I'd like to limit the length of the description fields, and then append a "..." to the end.
Is there any way to do that?

Found solution. Here's ASP.net code in case it helps anyone else:
<pre> <asp:DataList ID="DataList1" runat="server" DataSourceID="XmlDataSource1" BackColor="#333333"
BorderStyle="None" GridLines="Vertical" BorderColor="#333333" BorderWidth="0px">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%#XPath("pubDate")%>' Font-Names="Verdana" Font-Size="XX-Small"></asp:Label><br />
<asp:HyperLink ID="HyperLink1" runat="server" Text='<%#XPath("title")%>' NavigateUrl='<%#XPath("link")%>' Target="_blank" Font-Names="Verdana" Font-Size="Small"></asp:HyperLink><br />
<asp:Label ID="description_label" runat="server" Text='<%#XPath("description")%>'></asp:Label><br />
<br />
</ItemTemplate>
</asp:DataList>
Here's the code behind:
<pre> Protected Sub DataList1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles DataList1.ItemDataBound
Dim ShortDescriptionLabel As Label = CType(e.Item.FindControl("description_label"), Label)
If ShortDescriptionLabel.Text.Length > 200 Then
ShortDescriptionLabel.Text = ShortDescriptionLabel.Text.Substring(0, 200) & "..."
End If
ShortDescriptionLabel.Text = ShortDescriptionLabel.Text
End Sub

Your error has nothing to do with XML itself.
The call to DataNode.SelectSingleNode probably returns null. In fact, directly calling methods on method calls that are prone to return null is one of the worst coding habit someone can have.Here is what a good programmer would have done:
userid = DataNode.SelectSingleNode("Username");
if ((userid != null) && (!String.IsNullOrEmpty(userid.InnerText))
{
}
else
{
throw new NoUsernameNodeException();
}
Not checking for null values before using object references is one the worst thing to do, always leading to obscure error message "Object reference not set to an object".

Does anyone know how to write an XSLT to create this kind of grouping?
If you have any suggestions, I'd entertain any options.
Thanks

What kind of grouping? I'm not going to reverse engineer your XML to decipher the problem statement for you. If you understand your problem clearly, you should have no trouble stating it in a post.

Each record contains these elements: producttype, productname, productid, productprice
I want the elements to group under the producttype element, such as:
Original:
<products>
<item>
producttype
productname
productid
productprice
</item>
<item>
producttype
productname
productid
productprice
</item>
</products>
Desired:
<products>
<category>
<producttype></producttype>
<item>
productname
productid
productprice
</item>
<item>
productname
productid
productprice
</item>
</category>
<category>
<producttype></producttype>
<item>
productname
productid
productprice
</item>
<item>
productname
productid
productprice
</item>
</category>
</products>

The technique for this is known as the Muenchian Method (or Muenchian grouping[^]) and it involves the use of xsl:key in a rather clever way.
I just love Koalas - they go great with Bacon.

Hey all,
Are the following three XPath expression equivalent?
resolve-uri(@url)
resolve-uri(@url, base-uri(.))
resolve-uri(@url, static-base-uri())
Cheers!

I need to extract some results from a XML file. The XML sort of like the below (each day has a record). The results are expected to be imported into a table with four columns (Month, Total rain for each month, highest temp for each month, lowest tem for each month) and 12 rows (for each month).
Can anyone help to provide some solutions? how to retrive and do simply calculation for this scenario? Many thanks.

Hi guys!
I have a RelaxNG schema which defines a group of attributes called "common-attrs". Amongst these common attributes is the "xml:id" attribute which can be optionally applied to all elements within the schema.
Somehow, I need to make an exception to this rule. There is one element where all of the common attributes apply, but the "xml:id" attribute is required. How can I make an exception to this rule without having to manage to near identical common attribute groups?
Many thanks,
Lea Hayes

Hello,
I am developing quite complex workflow using SharePoint and Workflow foundation. The WF is started on a InfoPath form and through the process of the workflow values of fields are changed programaticaly in the infopath form.
So far I had only textboxes which I was changing using this method:
MemoryStream myInStream = new MemoryStream(lFile.OpenBinary());
XmlDocument myDoc = new XmlDocument();
myDoc.Load(myInStream);
XmlNode myRoot = myDoc.DocumentElement;
XmlNamespaceManager xmlNSManager = new XmlNamespaceManager(myDoc.NameTable);
XmlNode node = myRoot.SelectSingleNode("/my:fieldPath", xmlNSManager);
node.InnerText = "Text which I want to put in the textbox";
Now I have a Option button(Radio button), where you can swich from 3 values. I would like to be able to select one of these values programatically.
I've checked the XML definition of the InfoPath form and I thought that I could just use the InnerText property and insert the proper text(text of one of the choices). But that is not working.
I am new to InfoPath and I am not a member of any IP forums so I said I will try my luck here in CP 
thank you for any suggestions

Can anyone possibly let me know,
how can i use superscript and subscript in an xml.
I need to insert a chemical formula . eg; H2SO4 where 2 and 4 are subscript and show them in an xml.
How could i do it?
Is there tags such as "sub" and "sup" that we can use in an xml.
For eg;
<rss>
<chemical>Sulphuric Acid
<formula>H2SO4
If any one has the solution, pls let me know
Aspiring Techie,
Vishnu Nath

XML is just markup, it doesn't specify how things should look. It sounds as if you might need a markup language directed towards chemical formulas. I did a search and found CML - Chemical Markup Language: http://www.ch.ic.ac.uk/rzepa/cml/[^]. Maybe that's what you're looking for.
