C#: Sort xml node using attribute value

Question

Is there a way we can sort xmlnodes based on attribute values, consider I can\'t use linq. Since I\'m using .NET 2.0.

Example:

Answer 1

To sort use following:

var xml= xDoc.Element("Root")
                .Elements("I")
                .OrderByDescending(s => (int) s.Attribute("aa"));

Then to save it:

XDocument doc = new XDocument(new XElement("Root", xml));
doc.Save("C:\\Something.xml");

UPDATE

You can use XSLT for this:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:template match="/*">
        <xsl:copy>
            <xsl:for-each select="I">
                            <xsl:sort select="@aa" order="ascending"/>
                    <xsl:copy-of select="."/>
            </xsl:for-each>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

And invoke it (quoting How to apply an XSLT Stylesheet in C# ):

XPathDocument myXPathDoc = new XPathDocument(myXmlFile) ;
XslTransform myXslTrans = new XslTransform() ;
myXslTrans.Load(myStyleSheet);
XmlTextWriter myWriter = new XmlTextWriter("result.xml",null) ;
myXslTrans.Transform(myXPathDoc,null,myWriter) ;
