Thanks to allof u how have given pain to see my problem
i have an xml file having this tructure

<specifications>
      <row>
           <heading>MegaPixels(Effective)</heading>
           <data>6.0</data>
      </row>
      <row>
         <heading>MegaPixels(Total)</heading>
         <data>6.2</data>
      </row>
   </specifications>

the xslt file is this
   <table class="spec_item_table">

                <xsl:for-each select="specifications/row">
                  <tr class="spec_item_odd">
                    <td>
                      <xsl:value-of select="heading"></xsl:value-of>
                    </td>
                    <td>
                      <xsl:value-of select="data"></xsl:value-of>
                    </td>
                  </tr>
                </xsl:for-each>
              </table>

my problem is that for each row it should show different colors like
row1:grey color
row2.yellow

for that i used
<tr class="spec_item_odd">

bit it will have same for all the rows so i can achive this in xml .thanks

Usually a combination of the mod operator and the position() function will help. An easy way:

Code:

<tr class="spec_item_{(position() mod 2)}">

Then you need two CSS classes, spec_item_0 for even rows, spec-item_1 for odd rows.

Alternatively use xsl:call-template, or xsl:function in version 2.0 that returns odd or even:

Code:

  <xsl:template name="oddOrEven">
    <xsl:param name="position"/>
    <xsl:choose>
      <xsl:when test="$position mod 2 = 0">even</xsl:when>
      <xsl:otherwise>odd</xsl:otherwise>
    </xsl:choose>
  </xsl:template>

Then do:

Code:

<xsl:for-each select="specifications/row">
                  <tr>
<xsl:attribute name="class">
<xsl:text>spec_item_</xsl:text><xsl:call-template name="oddOrEven">
        <xsl:with-param name="position" select="position()"/>
      </xsl:call-template></xsl:attribute>
      <td>
      <xsl:value-of select="heading"></xsl:value-of>
      </td>
      <td>
      <xsl:value-of select="data"></xsl:value-of>
      </td>
      </tr>
    </xsl:for-each>
