    Problems using apply-templates to transform xml file - newbie

    I am a newbie at XML and really need some help.

    I'm having problems trying to create an XSLT style sheet to transform the xml file 'scene3.xml' (relevant code below):-

    Code:
    <?xml version="1.0" ?>
    <?xml-stylesheet type="text/xsl" href="scene3toXHTML.xsl"?>
    <PLAY>
    	<TITLE>The Tragedy of Macbeth</TITLE>
    		<ACT>
    		<TITLE>ACT I</TITLE>
    		<CHARACTERS>
    			<GROUP DESCRIPTION="Generals">
    				<PERSON>MACBETH</PERSON>
    				<PERSON>BANQUO</PERSON>
    			</GROUP>
    			<GROUP DESCRIPTION="Noblemen">
    				<PERSON>ROSS</PERSON>
    				<PERSON>ANGUS</PERSON>
    			</GROUP>
    			<GROUP DESCRIPTION="Witches">
    				<PERSON>FIRST WITCH</PERSON>
    				<PERSON>SECOND WITCH</PERSON>
    				<PERSON>THIRD WITCH</PERSON>
    			</GROUP>
    		</CHARACTERS>
    		<SCENE>
    			<TITLE>SCENE III.  A heath near Forres.</TITLE>
    			<STAGEDIR>Thunder. Enter the three Witches</STAGEDIR>
    The first portion of the desired output should look like the screenshot in the attached 'file1.png'. So far, I have managed to code the first 4 lines of code correctly, starting with 'The Tragedy of Macbeth, ACT 1, SCENE 111 A heath near Forres and Characters. After that, I can't get the list of characters to appear on separate lines. Also, I can get the 1st 'GROUP DESCRIPTION' title to appear, but the remaining two 'GROUP DESCRIPTION's don't appear at all.
    See XSLT code below:-

    Code:
    <?xml version="1.0"?>
    <xsl:stylesheet version="1.0"
    	xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    	
    <xsl:output method="xml" encoding="ISO-8859-1"
    	version="1.0" omit-xml-declaration="yes"
    	media-type="text/html" indent="yes" />
    	
    <xsl:template match="/">
    	
    	<html>
    	 <head>
    		<title>A Simple XSLT style sheet</title>
    		<meta http-equiv="content-type"
    		content="text/html; charset=iso-8859-1" />
    	    <link href="macbeth.css" rel="stylesheet" type="text/css" />
    	 </head>
    	<body>
    			<xsl:for-each select="PLAY">
    			
        <dl>
          <dt><xsl:apply-templates select="TITLE"/></dt>
    	  	<p></p>
    	  <dt><xsl:apply-templates select="ACT"/></dt>
    	  	<p></p>
    	  <dd><xsl:apply-templates select="ACT/SCENE"/></dd>
    	  	<p></p>
    	  	<hr />
    		<p></p>
    		<h3>Characters</h3><br />
    	  <dd><xsl:apply-templates select="ACT/CHARACTERS"/></dd>
    	</dl>
    	<dl>
        </dl>
    
    			</xsl:for-each>
    		
    		
    	</body>
    	</html>
    	
    </xsl:template>
    	
    <xsl:template match="TITLE">
      <xsl:value-of select="."/>
    </xsl:template>
     
    <xsl:template match="ACT">
      <xsl:value-of select="TITLE"/>
    </xsl:template>
    
    <xsl:template match="ACT/SCENE">
      <xsl:value-of select="TITLE"/>
    </xsl:template>
    
    <xsl:template match="ACT/CHARACTERS">
      <xsl:value-of select="GROUP/@DESCRIPTION"/>
      <xsl:value-of select="."/>
    </xsl:template>
    	
    </xsl:stylesheet>
    I would be very grateful for any help.
    Thanks.

    I,ve managed to get a bit further. For example, a section of the output looks as below:-

    Generals

    Macbeth Banquo

    What I want it to look like is:


    Generals

    Macbeth
    Banquo

    So, how do I get the line-space between Macbeth and Banquo. Below is my code and the relevant bit from where it starts is:-

    Code:
     <dd><xsl:apply-templates select="ACT/CHARACTERS/GROUP"/></dd>
    Code:
    <?xml version="1.0"?>
    <xsl:stylesheet version="1.0"
    	xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    	
    <xsl:output method="xml" encoding="ISO-8859-1"
    	version="1.0" omit-xml-declaration="yes"
    	media-type="text/html" indent="yes" />
    	
    <xsl:template match="/">
    	
    	<html>
    	 <head>
    		<title>A Simple XSLT style sheet</title>
    		<meta http-equiv="content-type"
    		content="text/html; charset=iso-8859-1" />
    	    <link href="macbeth.css" rel="stylesheet" type="text/css" />
    	 </head>
    	<body>
    			<xsl:for-each select="PLAY">
    			
        <dl>
          <dt><xsl:apply-templates select="TITLE"/></dt>
    	  	<p></p>
    	  <dt><xsl:apply-templates select="ACT/TITLE"/></dt>
    	  	<p></p>
    	  <dd><xsl:apply-templates select="ACT/SCENE/TITLE"/></dd>
    	  	<p></p>
    	  	<hr />
    		<p></p>
    		<h3>Characters</h3><br />
    	  <dd><xsl:apply-templates select="ACT/CHARACTERS/GROUP"/></dd>
    
        </dl>
    			</xsl:for-each>
    		
    		
    	</body>
    	</html>
    	
    </xsl:template>
    	
    <xsl:template match="TITLE">
      <xsl:value-of select="."/>
    </xsl:template>
     
    <xsl:template match="ACT/TITLE">
      <xsl:value-of select="."/>
    </xsl:template>
    
    <xsl:template match="ACT/SCENE/TITLE">
      <xsl:value-of select="."/>
    </xsl:template>
    
    <xsl:template match="ACT/CHARACTERS/GROUP">
      <p><xsl:value-of select="@DESCRIPTION"/></p>
      <p><xsl:value-of select="."/></p>
      <br />
    </xsl:template>
    	
    </xsl:stylesheet>
    Thanks

    Use apply-templates within apply-templates probably.
    I'm not sure why you're not associating everything with characters that belongs to characters. eg. like:
    Code:
    <dd><xsl:apply-templates select="ACT/SCENE"/></dd>
    	  	<p></p>
    	  	<hr />
    		<p></p>
                              <xsl:apply-templates select="ACT/CHARACTERS"/>
    	</dl>
    ...
    <xsl:template match="CHARACTERS">
    <h3>Characters</h3><br />
    <dd>
      <xsl:apply-templates/>
    </dd>
    </xsl:template>
    
    <xsl:template match="GROUP">
      <p><xsl:value-of select="@DESCRIPTION"/></p>
      <br />
      <xsl:apply-templates/>
      <br/>
    </xsl:template>
    <xsl:template match="PERSON">
      <p><xsl:value-of select="."/></p>
    </xsl:template>

    Thanks very much. I also have no idea as to why I didn't use 'template match = "PERSON" I'm learning a lot!

    Thanks again!
