Creating New Attributes

• Create new attributes using <xsl:attribute>

For example, given this XML document (animals.xml):

   <?xml version="1.0"?> 
   <animals>
      <animal name="dog" class="mammal" legs="4"/>
      <animal name="shark" class="fish" legs="0"/>
      <animal name="chicken" class="bird" legs="2"/>
   </animals>

Transform it to this XML document (pets.xml):

   <?xml version="1.0" encoding="UTF-8"?>
   <pets>
      <mammal name="dog" legs="4"/>
      <fish name="shark" legs="0"/>
      <bird name="chicken" legs="2"/>
   </pets>

We use this XSL Style Sheet:

   <?xml version="1.0"?> 
   <xsl:stylesheet version="1.0"
                   xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
      <xsl:output indent="yes"/>
      <xsl:template match="animals">
         <pets>
            <xsl:apply-templates select="animal"/>
         </pets>
      </xsl:template>

      <xsl:template match="animal">
         <xsl:element name="{@class}">
            <xsl:attribute name="name">
               <xsl:value-of select="@name"/>
            </xsl:attribute>
            <xsl:attribute name="legs">
               <xsl:value-of select="@legs"/>
            </xsl:attribute>
         </xsl:element>
      </xsl:template>
   </xsl:stylesheet>
