Plain text from Cocoon

Hi!

I wan't plain text output from cocoon, but somehow it gives an
error message unless i include som html-tags. How can i get plain 
text without the tags ?

My XML page looks like this :
------------------------------------------------------------------------
-
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="phonebook-plain.xsl" type="text/xsl"?>
<?cocoon-process type="xslt"?>
<Personalia>
	<Navn><Fornavn>Ole<Initialer>O.O</Initialer>
		</Fornavn>
		<Etternavn>Olsen</Etternavn>
	</Navn>
	<Navn><Fornavn>Per<Initialer>P.P</Initialer>
		</Fornavn>
		<Etternavn>Person</Etternavn>
	</Navn>
</Personalia>
------------------------------------------------------------------------
-
And my XSL page looks like this :
------------------------------------------------------------------------
-
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format">

	<xsl:template match="Personalia">
				<xsl:for-each select="Navn">
	 <xsl:value-of select="Fornavn" /> 
					     		
				</xsl:for-each>
			</xsl:template>
</xsl:stylesheet>
------------------------------------------------------------------------
---
The ERROR message looks like this :
------------------------------------------------------------------------

I had to wrap the text-content in a dummy element. My root template
looks like:

  <xsl:template match="/">
    <bouh>
Bla bla
...
    </bouh>
  </xsl:template>

Add a <?cocoon-format type="text/plain"?> in your xml, and the
TextFormatter will ignore the root element (i.e. it will take the
string value of it, IIRC).

Hi,

You have to use a root tag in xsl, but it won't show in the resulting
document if you set the format to text/plain.
Try this stylesheet:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format">
<xsl:template match="Personalia">
 <xsl:processing-instruction
name="cocoon-format">type="text/plain"</xsl:processing-instruction>
 <plain-text>
  <xsl:for-each select="Navn">
   <xsl:value-of select="Fornavn" />
  </xsl:for-each>
 </plain-text>
</xsl:template>
</xsl:stylesheet>

I understand what you mean, but when you look at XSLT it is true what I am
saying, and like I said, it depends also on the program that interprets the
output. In this case the program is Cocoon, and Cocoon knows to strip the
root element if the type is text/plain probably.

Ofcourse this last thing I did not know :P.

That's not necessarily true.  Otherwise XSP and VRML won't work.  The
way it works in Cocoon, is you must have root tags.  Everything can be
translated to text inside the base tags.  The TextSerializer or
similar mechanism in Cocoon 1 will strip out the root tags.

Example:

<root>
This is plain text.

We can have some more text.

And even some more.
</root>

When put through the TextSerializer, will strip the root tags and you get:

"This is plain text.

We can have some more text.

And even some more."

(quotes included to show that it is one string).

You probably can't. Because of the simple reason that XSL(T) is ment for
transforming one XML file to another. So you always have to make a XML tree
with XSLT, whatever the program that interprets the output does with it is
up to the program (for example transform it to a PDF or HTML document), but
you cannot use XSLT to create a plain text file without at least some root
tag.
