SharePoint 2010 Data View Webpart Displying URL Field

In SharePoint 2010, while displaying URL columns/fields, We can use @FiledName.desc.

Below is the example.

<xsl:choose>

      <xsl:when test="@OtherUrl1 != '' ">

           <div ><a  target="_blank"  href="{@OtherUrl1}">

                   <xsl:value-of select="@OtherUrl1.desc"/>

                </a>

          </div>

       </xsl:when>

     <xsl:otherwise>

     </xsl:otherwise>

</xsl:choose>

The below code doesn't work, if you have tried already.

<a href="{substring-before(@OtherUrl1,',')}" style="border:none !important;">

            <xsl:value-of select="substring-after(@OtherUrl1,',')"/>

 </a>
