Question

xslt and xpath: match two node attributes

Answer 1

+1 A:

The problem is the whitespace:

<takes> CMPE351 </takes>

should be:

<takes>CMPE351</takes>

I'll try to compensate... example on the way... To avoid a lot of problems (and improve performance), I'll also use an xsl index...

Fixed (caveat - it won't work with course codes with multiple spaces in the middle of them, but that seems unlikely):

<xsl:variable name="code" select="normalize-space()"/>
<ul>
  <li>
    <xsl:value-of select="$code"/>
    <xsl:value-of select="key('courses',$code)/courseName"/>
  </li>
</ul>

with (at the top) the xsl index:

<xsl:key name="courses" match="/school/course" use="@courseCode"/>

You are right the problem spaces in takes node. Also I changed text() to current() then it worked properly thx. <xsl:value-of select = "../../course[@courseCode=current()]/courseName"/>But your code is also working with spaces thx very much.

Answer 3

A:

I worked up this example just before you already had a good answer. Since it's just a slightly different approach, I thought I'd post it anyways.


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

<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt;

  <xsl:output method="html" indent="no" encoding="UTF-8" omit-xml-declaration="yes" />

  <xsl:key name="courses" match="course" use="@courseCode"/>

  <xsl:template match="school">
      <html>
        <body>
          <p>Courses taken by:</p>
          <ul>
            <xsl:apply-templates select="student"/>
          </ul>
        </body>
      </html>
  </xsl:template>

  <xsl:template match="student">
    <li>
      <xsl:value-of select="name"/>
      <ul>
        <xsl:apply-templates select="takes"/>
      </ul>
    </li>
  </xsl:template>

  <xsl:template match="takes">
    <li>
      <xsl:value-of select="."/>
      <xsl:value-of select="key('courses', normalize-space(.))/courseName"/>
    </li>
  </xsl:template>

</xsl:stylesheet>

That isn't very different... the same use of normalize-space and xsl:key - the only difference is the use of xsl:variable, which isn't an important difference.

Marc Gravell 2009-05-16 21:15:56

True, but the slight difference I had in mind was the original use of xsl:for-each versus xsl:template here.
