[xsl] formatting not able to retain

Dear experts,
We are not able to retain formatting elements ie. bold, italic within following 
example. At the same time title text is also gets duplicate. Can anyone give me 
any clue regarding this. Thanks in advance

XSL
<xsl:template match="preformat">
 <literallayout type="programlisting">
  <xsl:apply-templates 
select="named-content[@content-type='list-head']/named-content[@content-type='label']"
 mode="list-label"/>
  <xsl:apply-templates select="named-content[@content-type='list-head']"/>
   <xsl:variable name="text" select="replace(., '  ', ' &#160;')"/>
   <xsl:analyze-string select="$text" regex="[\n\r]">
      <xsl:non-matching-substring>
       <line><xsl:value-of select="."/></line>
    </xsl:non-matching-substring>
   </xsl:analyze-string>
</xsl:template>

Input
<preformat id="list1">
<named-content content-type="list-head">
<named-content content-type="label">Listing 3.1</named-content> Listing 
Head</named-content>
01 <bold>public class</bold> Mitarbeiter {
02   <italic>// Attribute</italic>
03   private final String name;
04   private&ndash;final int personalNummer;
05   private double gehalt;}
</preformat>

Current output
<literallayout type="programlisting" id="list1">
<number>Listing 3.1</number><ti>Listing Head</ti>
<line>Listing 3.1 Listing Head</line>
<line>01 public class Mitarbeiter {</line>
<line>02 Â  // Attribute</line>
<line>03 Â  private final String name;</line>
<line>04   private–final int personalNummer;</line>
<line>05 Â  private double gehalt;}</line>
</literallayout>

Required output
<literallayout type="programlisting" id="list1">
<number>Listing 3.1</number><ti>Listing Head</ti>
<line>01 <b>public class</b> Mitarbeiter {</line>
<line>02 Â  <i>// Attribute</i></line>
<line>03 Â  private-final String name;</line>
<line>04   private–final int personalNummer;</line>
<line>05 Â  private double gehalt;}</line>
</literallayout>
