Specifying Patterns for the match Attribute (6)

Testing with []

• Test whether a certain condition is true, for example:
• student element with a child name element
  <xsl:template match="student[name]">
• Any element that has a name element
  <xsl:template match="*[name]">
• student element that has either hw1 or hw2 element
  <xsl:template match="student[hw1 | hw2]">

Example:   Name of the student with id 'js'

XSL Style Sheet:

   <?xml version="1.0"?> 
   <xsl:stylesheet version="1.0" 
                   xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
      <xsl:template match="course">
         <NAME>
            <xsl:apply-templates select="student"/>
         </NAME>
      </xsl:template>

      <xsl:template match="text()">
      </xsl:template>

      <xsl:template match="student[@id = 'js']">
         <xsl:value-of select="name"/> 
      </xsl:template>
   </xsl:stylesheet>
