XSL - blank attribute

["Kazmír, Jaroslav" <ja...@joanneum.at>]

Hello,
I have a XSL stylesheet like this:
 
...
<xsl:template match="table">
      <table>
         <xsl:attribute name="width">
            <xsl:value-of select="@width" />
         </xsl:attribute>
 
         <xsl:attribute name="height">
            <xsl:value-of select="@height" />
         </xsl:attribute>
 
         <xsl:attribute name="cellspacing">
            <xsl:value-of select="@cellspacing" />
         </xsl:attribute>
 
         <xsl:attribute name="cellpadding">
            <xsl:value-of select="@cellpadding" />
         </xsl:attribute>
 
         <xsl:attribute name="bordercolor">
            <xsl:value-of select="@bordercolor" />
         </xsl:attribute>
 
         <xsl:attribute name="class">
            <xsl:value-of select="@class" />
         </xsl:attribute>
 
         <xsl:for-each select="row">
            <tr>
                <xsl:attribute name="bgcolor">
                   <xsl:value-of select="@bgcolor" />
                </xsl:attribute>
 
               <xsl:for-each select="data">
                  <td>
                     <xsl:attribute name="valign">
                        <xsl:value-of select="@valign" />
                     </xsl:attribute>
 
                     <xsl:attribute name="class">
                        <xsl:value-of select="normalize-space(@class) " />
                     </xsl:attribute>
 
                     <xsl:attribute name="height">
                        <xsl:value-of select="@height" />
                     </xsl:attribute>
 
                     <xsl:attribute name="width">
                        <xsl:value-of select="@width" />
                     </xsl:attribute>
 
                     <xsl:apply-templates />
                  </td>
               </xsl:for-each>
            </tr>
         </xsl:for-each>
      </table>
   </xsl:template>
...
My problem is, that the output looks like with empty attributes:
 
<table .. height="" width="" ...>
 <tr ...bgcolor="">
   <td valign="center" class="">
    .... Some text ...
   </td>
 <tr>
<table>
 
Do you anyone know how could I erase all emty attributes in the output? I
don't want to write conditions into XSL file for every attibute.
Output will be better to see like:
 
<table>
 <tr>
  <td valign="center">
   ... Some text ...
  </td>
 <tr>
</table>
 
Thanx a lot for your help and advice.
