My font type is stored in xml (Arial,Times New Roman) i want to read it in css it is possible?

You have an XML file containing layout data that you want transformed into HTML by your XSLT transform at runtime.

Yes, the .NET framework facilitates this. Here is a snipped from the sitemap on my web site that is transformed at run-time. Instead of having a manually maintained sitemap.xml for search engines.

My XML:

<site xmlns="http://redcell.ca/schema/sitemap.xsd" baseurl="http://two-red-cells.com/">
    <page id="services" type="category">
        <page id="3d modelling" type="content" />
        <page id="archiving" type="content" />
        <page id="ipad" type="content" />
        <page id="proofreading" type="content" />
        <page id="web" type="content" />
        <page id="writing" type="content" />
    </page>
    <page id="solutions" type="category">
        <page id="barcoding" type="content" />
        <page id="crowdsourcing" type="content" />
        <page id="intelligent forms" type="content" />
        <page id="nui" type="content" />
        <page id="rfid" type="content" />
        <page id="rtls" type="content" />
        <page id="social mining" type="content" />
        <page id="telemetry" type="content" />
    </page>
    <page id="information" type="category">
        <page id="sitemap" type="content" />
        <page id="contact" type="content" />
        <page id="articles" type="content" />
        <page id="mobile" type="link" />
        <page id="news" type="content" />
        <page id="surplus" type="content" />
        <page id="twitter" type="link" />
    </page>
</site>

My XSLT:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" xmlns:s="http://redcell.ca/schema/sitemap.xsd">
    <xsl:output method="xml" indent="yes" />

    <xsl:template match="/">
        <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
            <url>
                <loc><xsl:value-of select="s:site/@baseUrl" /></loc>
                <changefreq>daily</changefreq>
                <priority>1.0</priority>
            </url> 
            <xsl:for-each select="//s:page[@type='category']">
                <url>
                    <loc><xsl:value-of select="/s:site/@baseUrl" /><xsl:value-of select="@id" />/</loc>
                    <changefreq>daily</changefreq>
                    <priority>0.75</priority>
                </url> 
            </xsl:for-each>
            <xsl:for-each select="//s:page[@type='content']">
                <url>
                    <loc><xsl:value-of select="/s:site/@baseUrl" /><xsl:value-of select="parent::s:page/@id" />/<xsl:value-of select="@id" /></loc>
                    <changefreq>daily</changefreq>
                    <priority>0.50</priority>
                </url> 
            </xsl:for-each>
        </urlset>
        <xsl:apply-templates select="@* | node()" />
    </xsl:template>
</xsl:stylesheet>

The transformation code:

using System;
using System.IO;
using System.Web.UI;
using System.Xml.Xsl;

/// <summary>
/// Dynamically transforms our XML sitemap into a google sitemap.
/// </summary>
public partial class sitemap : Page
{
    private string _language;
    private const string Stylesheet = "sitemap.xml.xslt";

    protected override void Render(HtmlTextWriter writer)
    {
        // Load the stylesheet into a transformer.
        var xslt = new XslCompiledTransform();
        var path = Path.Combine(Globals.SitePath, @"sitemaps\" + Stylesheet);
        xslt.Load(path);

        // Transform!
        var args = new XsltArgumentList();
        var filename = "sitemap." + _language + ".xml";
        path = Path.Combine(Globals.SitePath, @"sitemaps\" + filename);
        xslt.Transform(path, args, writer);
    }
}
