Processing issue.....

Hi,
I am having problems with an image string which prints the string to 
the screen instead of loading the image!

1. in my xsp page I first build up the image string as so:

<xsp:logic>
	String num = "39";
	StringBuffer sb = new StringBuffer()
	.append("&lt;img src=\"")
	.append(num)
	.append(".jpg\" border=\"0\" width=\"200\" height=\"200\" /&gt;");
	
	String artist1 = sb.toString();
</xsp:logic>

<page>
	<artists-photo1>
		<xsp:expr>artist1</xsp:expr>
	</artists-photo1>
</page>

2. In my XSL page I do the following(snippet....):
    ..........
	<tr>
		<td><xsl:apply-templates select="//artists-photo1"/></td>
	</tr>

	</table>
				
	</body>
	</html>		
</xsl:template>

<xsl:template match="artists-photo1">
<xsl:apply-templates />
</xsl:template>	

What am I doing wrong?

The XML output generated to the screen is (snippet..), which looks ok 
to me but doesn't process the image tag line!!!:

-
	<body>
-
	<table leftmargin="0" marginheight="0" cellspacing="0" cellpadding="0" 
border="0">
</tr>
-
	<tr>
-
	<td>

				<img src="39.jpg" border="0" width="200" height="200" />
			
</td>
</tr>
</table>
</body>
</html>


many thanks in advance...

Simple - a Cocoon pipeline is a pipeline of sax events.  Sax is an event 
based representation of pre-parsed xml, and so handles element events 
and character events separately.  The code you showed results in 
inserting character events into the sax stream which will never be 
interpreted as element events.  Look into xsp:element and xsp:attribute 
to accomplish what you are trying to do.
