Answer 1

There's a dozen different ways to do this. Here's a very simple example using XSL :

mytransform.xsl:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
    <xsl:for-each select="items/item">
        <xsl:value-of select="@name" />, <xsl:value-of select="@id" />, <xsl:value-of select="filter/@value" />
    </xsl:for-each>
</xsl:template>

We load the XSL file into a transform object; specify an input XML and an output text file:

XslTransform xslt = new XslTransform();
xslt.Load("c:\\path\\mytransform.xsl");
xslt.Transform("c:\\path\\input.xml", "c:\\path\\output.txt");

Check out the documentation on XslTransform for more in-depth usage, like working in memory streams and XML objects instead of file paths. This demonstrates the core concepts though.

XDocument xml = XDocument.Load("foo.xml");
string csv = string.Join("\n",
    xml.Descendants("item").Select(item =>
        string.Format("{0}, {1}, {2}",
            (string)item.Attribute("name"),
            (string)item.Attribute("id"),
            (string)item.Elements("filter")
                        .Single(f => f.Attribute("name") == "itemLevel")
                        .Attribute("value")))
       .ToArray());
