Working with Both xsl:if and xsl:choose in XSLT - Nesting xsl:if within another

(Page 2 of 6 )

In the previous section, I already introduced "xsl:if."  And now, I want to nest "xsl:if" within another and make things a bit complicated.  To do that, we may have to modify our business need. 

Let us modify our business need in such a way that I would like to have all the employee details listed with:

• salary in red, if earnings are more than 4000
• salary in blue, if earnings are more than 3000 and less than 4000
• salary must not be shown for the employees working in department 10

The entire XSLT code for the above business need is as follows:

<?xml version="1.0" encoding="utf-8"?>

<xsl:stylesheet version="1.0"

    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">

      <table border="1">

      <xsl:apply-templates select="SQLData/Rows" />

      </table>

</xsl:template>  

<xsl:template match="SQLData/Rows">

      <tr>

            <td>

                  <xsl:value-of select="Empno"/>

            </td>

            <td>

                  <xsl:value-of select="Ename"/>

            </td>

            <xsl:apply-templates select="Sal" />

            <td>

                  <xsl:value-of select="Deptno"/>

            </td>

      </tr>

</xsl:template>

<xsl:template match="Sal">

      <xsl:if test="./following::Deptno[1]/text() != '10'">

            <xsl:if test="text() &gt; '4000'">

                  <td style="color: red">

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

                  </td>

            </xsl:if>

            <xsl:if test="text() &gt; '3000' and text() &lt; '4000'">

                  <td style="color: blue">

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

                  </td>

            </xsl:if>

            <xsl:if test="text() &gt; '0' and text() &lt; '3000'">

                  <td>

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

                  </td>

            </xsl:if>

      </xsl:if>

      <xsl:if test="./following::Deptno[1]/text() = '10'">

            <td>

                  NA

            </td>

      </xsl:if>

</xsl:template>

</xsl:stylesheet>

When the above code gets executed, you are likely to get the following transformation:

<table border="1">

      <tr>

            <td>1001</td>

            <td>Jag</td>

            <td>

                  NA

            </td>

            <td>10</td>

      </tr>

      <tr>

            <td>1002</td>

            <td>Chat</td>

            <td>2800</td>

            <td>20</td>

      </tr>

      <tr>

            <td>1003</td>

            <td>Winner</td>

            <td>

                  NA

            </td>

            <td>10</td>

      </tr>

      <tr>

            <td>1004</td>

            <td>Dhan</td>

            <td style="color: red">5000</td>

            <td>20</td>

      </tr>

</table>

Within the above XSLT code, the most confusing issue will be the following:

xsl:if test="./following::Deptno[1]/text() != '10'">

That tests whether the next sibling node named "Deptno" does or does not equal 10. If you are new to this, I suggest you to refer my second article in this series.
