Breaking larger xml document into smaller ones

Hi All,
I have a problem which I think is sure easy enough that it would have been
solved already. I am looking for some pointers here -

I have an XML document like this:

<root>
<child>
<element1>value1</element1>
<element2>value2</element2>
</child>
<child>
<element1>value1</element1>
<element2>value2</element2>
</child>
....
....
</root>

The <childsection like the one above, might repeat for hundreds of
thousands of times. Since I am going to process this XML later for some
other thing, I want to break it in smaller chunks, say XML documents of 5000
child records each.

Is there a reasonable way to achieve this? I am using C# .Net 2.0 and Visual
Studio 2005.

Thanks in advance,
Abhishek

Use a combination of XmlReader and XmlWriter where you pull in the input
XML with XmlReader and create a new document with XmlWriter for each
chunk of 5000 child records.
XmlWriter has a method WriteNode that takes an XmlReader
http://msdn.microsoft.com/en-us/library/1wd6aw1b.aspx
so you can simply copy those 'child' elements from the XmlReader to the
XmlWriter.

Thanks Martin,
I will try to experiment with these and then come back if I have more
questions.
