Pretty good news for a project born only two months ago:
&lt;p&gt;
Page views: 1.421&lt;br/&gt;
Downloads: 243&lt;br/&gt;
Last 30 days we've had a steady rate of increase in page views of 200% a day, and 150% in downloads.&lt;/p&gt;&lt;img src ="http://weblogs.asp.net/cazzu/aggbug/119940.aspx" width = "1" height = "1" /&gt;</description></item><item><dc:creator>Daniel Cazzulino</dc:creator><title>Reading XML fragments with XmlTextReader</title><link>http://weblogs.asp.net/cazzu/archive/2004/04/23/119263.aspx</link><pubDate>Fri, 23 Apr 2004 21:51:00 GMT</pubDate><guid>http://weblogs.asp.net/cazzu/archive/2004/04/23/119263.aspx</guid><wfw:comment>http://weblogs.asp.net/cazzu/comments/119263.aspx</wfw:comment><comments>http://weblogs.asp.net/cazzu/archive/2004/04/23/119263.aspx#Feedback</comments><slash:comments>4</slash:comments><wfw:commentRss>http://weblogs.asp.net/cazzu/comments/commentRss/119263.aspx</wfw:commentRss><trackback:ping>http://weblogs.asp.net/cazzu/services/trackbacks/119263.aspx</trackback:ping><description>		&lt;p&gt;Back at the &lt;a href="http://mvp.support.microsoft.com/default.aspx?scid=fh;en-us;mvpsmt2004"&gt;
				2004 MVP Global Summit&lt;/a&gt;, I met fellow XML fan &lt;a href="http://weblogs.asp.net/kaevans"&gt;
				Kirk&lt;/a&gt;, who was seeking a solution to the following problem: you have a 
			(several) megabytes file containing multiple XML fragments, and you want to 
			read it (in &lt;a href="http://weblogs.asp.net/kaevans/archive/2004/04/24/119508.aspx"&gt;his case&lt;/a&gt; specially through the &lt;a href="http://www.gotdotnet.com/Community/UserSamples/Details.aspx?SampleGuid=B90FDDCE-E60D-43F8-A5C4-C3BD760564BC"&gt;SgmlReader&lt;/a&gt;). The problem is, of course, that the &lt;code&gt;XmlTextReader&lt;/code&gt; will 
			throw an exception as soon as it finds the second fragment, unless you use the special ctor. overload that takes an &lt;code&gt;XmlParsingContext&lt;/code&gt;.&lt;a href="http://www.25hoursaday.com/"&gt;
				Dare&lt;/a&gt; &lt;a href="http://msdn.microsoft.com/xml/default.aspx?pull=/library/en-us/dnxmlnet/html/largexml.asp"&gt;
				shows&lt;/a&gt; an alternate solution based on XML inclusion techniques, either DTD external 
			entities or &lt;a href="http://workspaces.gotdotnet.com/xinclude"&gt;XInclude&lt;/a&gt;.
		&lt;/p&gt;
		&lt;P&gt;These techniques effectively expose a fully well-formed document to your application, which has a number of 
benefits, including the ability to transform it if you need to, for example. But I was thinking more along the lines of providing a class that could actually read the fragments without resorting to those mechanisms. I couldn't cheat the &lt;code&gt;XmlTextReader&lt;/code&gt;, so I 
			decided to go one step lower. The result is the &lt;code&gt;XmlFragmentStream&lt;/code&gt;, 
			a class that wraps any &lt;code&gt;System.IO.Stream&lt;/code&gt; and fakes the missing root 
			element, so that an &lt;code&gt;XmlTextReader&lt;/code&gt; layered on top of it, will think
