Can any one tell how to dynamically change the style on td tag.
I have a code in XSLT file which should get the style and assign to td tag.

I have below code in XSLT, where I need style for td for $QuestionIndex+1 value in the code. Problem is how to dynamically generate td style.

XML

<xsl:when test ="../../@IsQID='True'">
                  <tr>
                    <td valign="top" width="1%" noWrap="yes" >
                        <xsl:if test="@QuestionType!='INS' and @QuestionType!='MAT'">
                        <xsl:if test="../../@IsQUnderline='True'">__</xsl:if>
                        <xsl:if test="../../@IsQNumber='True'">
                            <xsl:value-of select="$QuestionIndex+1" />.<!--plus 1 to include current questions-->
                        </xsl:if>
                      </xsl:if>
                    </td>
                    <td align="left" width="99%" class="tdNumCls">
                      <xsl:value-of select ="ID"/>
                    </td>
                  </tr>
                  <tr>
                    <td valign="top" width="1%" noWrap="yes" >
                    </td>
                    <td align="left" width="99%" class="tdNumCls">
                      <xsl:if test="../../@IsQStem='True'">
                        <xsl:value-of select="Stem/text()" disable-output-escaping="yes"/>
                      </xsl:if>
                    </td>
                  </tr>
                </xsl:when>

Nooo. I need style like Font-size:11 pt; Font-weight:Bold; Font-style:Arial. In below line of code @QuestionIndexFont actually is XMLDocument Attribute. Where I'm assigning Font style with Font-size:11 pt; Font-weight:Bold; Font-style:Arial

I tried with Font style like this shown below. But, not able to assign font to the questionIndex value

XML

<font style="{@QuestionIndexFont}">
                                <xsl:value-of select="$QuestionIndex+1" />.<!--plus 1 to include current questions-->
                            </font>

But, same code works with

XML

<font style="Font-size:11pt; Font-weight:bold">
                                <xsl:value-of select="$QuestionIndex+1" />.<!--plus 1 to include current questions-->
                            </font>

QuestionIndexFont changes. How should i assign font style ?

So you want to set the style attribute on a TD and you want to set it to something based on a numeric variable named $QuestionIndex? I'll assume this is the TD you want to apply that to:

XML

<td valign="top" width="1%" noWrap="yes" >
</td>

I'll assume that you want to set the font color to "Red" or "Green" depending on the value of $QuestionIndex:

XML

<td valign="top" width="1%" noWrap="yes">
	<xsl:attribute name="style">
		<xsl:choose>
			<xsl:when test="$QuestionIndex = 1">
				<xsl:value-of select="'color: Red;'" />
			</xsl:when>
			<xsl:otherwise>
				<xsl:value-of select="'color: Green;'" />
			</xsl:otherwise>
		</xsl:choose>
	</xsl:attribute>
</td>

EDIT: Your description is still confusing, but let me try again based on what I now think you want. So @QuestionIndexFont will have the style information (font size, font weight) stored as a string, and you want to apply that to the style attribute of a TD element which contains the value stored in $QuestionIndex + 1. So @QuestionIndexFont might contain "Font-size: 11pt; Font-weight: bold;" and $QuestionIndex might be equal to the number 3 (note: not the string "3"). When all is said and done, you want the HTML to look like this:

HTML

<td style="Font-size: 11pt; Font-weight: bold;">
    4
</td>

To do that, you'd use this XSLT:

XML

<td>
    <xsl:attribute name="style">
        <!-- Note: if this isn't the right way to select an attribute, let me know. -->
        <xsl:value-of select="@QuestionIndexFont" />
    </xsl:attribute>
    <xsl:value-of select="$QuestionIndex + 1" />
</td>

If that's not correct, then please try to explain what it is you really want. And don't post it as another answer that I will have to delete... post it as an update to your question then comment on this answer to let me know you made that update.

EDIT: Just a tip to help you debug. If you want to see what the XML input is in your output, you just do this:

XML

<xsl:copy-of select="." />

IIRC, that should give you a copy of the entire XML structure as it exist at that point in the code. You can use that to see if you're getting the expected data.
