Working with Expressions, Variables and xsl:for-each in XSLT - Working with xsl:for-each in XSLT

(Page 3 of 6 )

Let us consider that I would like to display all the employee details in the form of a table without using templates. 

The following is a simple solution to bring this about:

<?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 width="50%" cellspacing="0" cellpadding="0" style="font-
family:verdana;font-size:X-Small" border="1">

                  <tr bgcolor="#336699">

                        <th align="left">

                              <font color="White">ID</font>

                        </th>

                        <th align="right">

                              <font color="White">Name</font>

                        </th>

                        <th align="right">

                              <font color="White">Salary</font>

                        </th>

                        <th align="right">

                              <font color="White">Department</font>

                        </th>

                  </tr>

                  <xsl:for-each select="SQLData/Rows">

                        <tr>

                              <td align="left">

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

                              </td>

                              <td align="right">

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

                              </td>

                              <td align="right">

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

                              </td>

                              <td align="right">

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

                              </td>

                        </tr>

                  </xsl:for-each>

            </table>

      </xsl:template>

</xsl:stylesheet>

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

<table width="50%" cellspacing="0" cellpadding="0" style="font-
family:verdana;font-size:X-Small" border="1">

      <tr bgcolor="#336699">

            <th align="left">

                  <font color="White">ID</font>

            </th>

            <th align="right">

                  <font color="White">Name</font>

            </th>

            <th align="right">

                  <font color="White">Salary</font>

            </th>

            <th align="right">

                  <font color="White">Department</font>

            </th>

      </tr>

      <tr>

            <td align="left">1001</td>

            <td align="right">Jag</td>

            <td align="right">4400</td>

            <td align="right">10</td>

      </tr>

.

.

.    

</table>

The most important construct from the above XSLT is the following:

<xsl:for-each select="SQLData/Rows">

.

.

</xsl:for-each>

The above construct automatically iterates for every presence of “SQLData/Rows.”  The execution of that construct gets completed only if no more “SQLData/Rows” are available for processing.  We can even nest “xsl:for-each” constructs according to our requirements.
