I have a problem between XML and XSL files. In XML file, there are some elements such as
*<school>
<student studentID="12345">
<name>Stud I</name>
<takes>CMPE471</takes>
<takes>CMPE412</takes>
<takes>CMPE100</takes>
</student>

<student studentID="67890">
<name>Stud II</name>
<takes>CMPE471</takes>
<takes>CMPE412</takes>
</student>

<course courseCode="CMPE471">
<courseName>NAME I </courseName>
<description>DESC I </description>
</course>

<course courseCode="CMPE412">
<courseName>NAME II </courseName>
<description>DESC II </description>
</course>

<course courseCode="CMPE100">
<courseName>NAME III </courseName>
<description>DESC III </description>
</course>

In XSL file,I want to reach "description" element which I specified "courseCode".
Output should be like this,
1. Stud I
     a. CMPE471 Desc I
     b. CMPE412 Desc II
     c. CMPE100 Desc III

2. Stud II
     a. CMPE471 Desc I
     b. CMPE412 Desc II

In XSL file, I tried to write something :

<ol>
<xsl:for-each select="/school/student">
<xsl:sort data-type="text" order="ascending" select="name"/>

<li><xsl:value-of select="name"/>

<ol type="a">
<xsl:for-each select="takes">
<xsl:sort data-type="text" select="text()" order="ascending"/>
<li>

<xsl:for-each select="/school/course">//PROBLEM
<xsl:value-of select="description [@courseCode = text()]"/>//PROBLEM
</xsl:for-each>//PROBLEM

</li> </xsl:for-each> </ol> </xsl:for-each> </ol>
Thanks.
