In this example I will generate a XML site-map that complies with the sitemap-protocol XML schema.
[code:c#]
//create datasource
List<string> blogPosts = new List<string>{
"http://blog.newguid.net/mypost1.aspx",
"http://blog.newguid.net/mypost_about_Net.aspx",
"http://blog.newguid.net/morePosts.aspx",
"http://blog.newguid.net/andEvenMorePosts.aspx"
};
//Create namespace for sitemap-protocol
XNamespace xmlNS = "http://www.sitemaps.org/schemas/sitemap/0.9";
XDocument xmlDoc =
new XDocument(
new XDeclaration("1.0", "UTF-8", null),
new XElement(xmlNS + "urlset",
from blogPostUrl in blogPosts
select
new XElement(xmlNS + "url",
new XElement(xmlNS + "loc", blogPostUrl))
));
//Show output
Response.Write(xmlDoc);
[/code]
This example will give the following output:
[code:xml]
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <url> <loc>http://blog.newguid.net/mypost1.aspx</loc> </url> <url> <loc>http://blog.newguid.net/mypost_about_Net.aspx</loc> </url> <url> <loc>http://blog.newguid.net/morePosts.aspx</loc> </url> <url> <loc>http://blog.newguid.net/andEvenMorePosts.aspx</loc> </url></urlset>
[/code]
To keep the example as simple as possible I only use the LOC element of the URL node. In the real world you can implement the lastmod, changefreq and priority node.

I was using some web-services that returned there values in an XmlElement. I needed to convert this XmlElement to something that I can use with LINQ. I didn't find good solutions on the internet. So I started building my own convert logic. After all kinds of solutions I ended up with creating an new XmlDocument, adding the XmlElement to the XmlDocument and then convert the innerXml of the XmlDocument to an XElement. Not really nice but it does the trick.
I've rewritten the code into a Extension Method for the XmlElement.
public static XElement ToXElement(this XmlElement xml)
{
XmlDocument doc = new XmlDocument();
doc.AppendChild(doc.ImportNode(xml, true));
return XElement.Parse(doc.InnerXml);
}
You use the Extension Method like this:
XmlElement xmlElement = wsClient.DoWebServiceRequest();
XElement xml = xmlElement.ToXElement();
Please tell me if you have a better way of doing this!
Cheers,
Pieter

Because every eveloper needs to have a New Guid generator and .Net info search iGoogle widget ;-). It was time for me to create one!
I had no idea where to start, try searching Google no good results. But after clicking along on iGoogle I found the Google Gadgets developer site. After reading some documents and playing with some examples I found out that it is to easy to create a iGoogle widget. Here is a ... step guide to create a iGoogle widget.
In this guide where going to load an external website (http://www.newguid.net/iGoogle_CreateGuid.aspx) in the widget (the most easy way to build a widget).
Step 1:
Go to the Google getting started document and scroll down to the Google Gadgets Editor. Here you can try out some examples or insert your own code.
Step 2:
Insert the following code to the Gadgets Editor
[code:html]
<?xml version="1.0" encoding="UTF-8"?><Module> <ModulePrefs title="[Widget Title]" height="100" author="[Author Name]" author_email="[Author Email]" description = "[Widget Description]" screenshot = "[Link to a Screenshot]" thumbnail = "[Link to a thumbnail]" author_link = "[Link to author website]"><Require feature="dynamic-height"/> </ModulePrefs> <Content type="url" href="http://www.newguid.net/iGoogle_CreateGuid.aspx"/></Module>
[/code]
Press the Preview tab. You will see that the New Guid widget is already working. The widget just loads the website within an Iframe. The best thing is that you only have to design an build your widget once on your own server. It is a normal page so there aren't any design limits.
Step 3:
Save and Publish your widget. You have to change all properties (eg. title, author, author_email, etc.) in de code before you save and publish your widget. After you've changed the properties you can just save and then publish your widget. You can either publish your widget on your webpage (just by linking to it) or publish it into the Google Directory or both.
Publish your gadget in the editor by going to File > Publish. This button is only clickable if your syntax is correct.
Your gadget will be validated before the real publish. Fix all the issues that show in popup (see image below). And retry.
Like I told you to easy. Ofcourse you can do mutch more with it, but this will do for most of your widgets.
