Examples of Using "for-each" Elements

This section provides a tutorial example on how to use 'for-each' elements to loop through a set of elements, attributes, text contents and comments.

Now we are ready to do more complex tests to see the power of XSLT loop statements. Let's revise our dictionary.xsl:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- dictionary.xsl, version 2.0
 - Copyright (c) 2014, HerongYang.com, All Rights Reserved.
-->
 <xsl:template match="dictionary">
  <pre>
d_dictionary
  <xsl:for-each select="word">
w__<xsl:value-of select="name()"/>
   <xsl:apply-templates select="."/>
  </xsl:for-each>
  </pre>
 </xsl:template>
 <xsl:template match="word">
  <xsl:for-each select="@*">
a___<xsl:value-of select="name(.)"/>=<xsl:value-of select="."/>
  </xsl:for-each>
  <xsl:for-each select="*">
e___<xsl:value-of select="name()"/>
   <xsl:apply-templates select="."/>
  </xsl:for-each>
 </xsl:template>
 <xsl:template match="name">
  <xsl:for-each select="text()">
t____<xsl:value-of select="."/>
  </xsl:for-each>
 </xsl:template>
 <xsl:template match="definition">
  <xsl:for-each select="text()">
t____<xsl:value-of select="."/>
  </xsl:for-each>
 </xsl:template>
 <xsl:template match="update">
  <xsl:for-each select="@*">
a____<xsl:value-of select="name(.)"/>=<xsl:value-of select="."/>
  </xsl:for-each>
 </xsl:template>

Opening dictionary_xsl.xml with Internet Explorer, I got:

d_dictionary
  
w__word
a___acronym=true
e___name
t____XML
e___definition
t____eXtensible Markup 
Language.
e___update
a____date=2002-12-23
w__word
a___symbol=true
e___name
t____<
e___definition
t____Mathematical symbol representing the "less than" logical 
operation, like: 1<2.
e___definition
t____Reserved symbol in XML representing the beginning of 
tags, like: 
t____<p>Hello world!</p>
