Hi, im havinf some trouble creating a Generator in XSP and after that
aplying a transformer in XSL, the problem is, that i am not able to parse
the XML returned by the generator with the transformer.

Generator code
<xsp:page language="java" xmlns:xsp="http://apache.org/xsp";>

    <xsp:structure>
        <xsp:include>pt.laseeb.dae.xmlDbApi.daeXmlDbApi</xsp:include>
        <xsp:include>org.xmldb.api.base.ResourceIterator</xsp:include>
        <xsp:include>org.xmldb.api.base.Resource</xsp:include>
        <xsp:include>org.xmldb.api.base.XMLDBException</xsp:include>
    </xsp:structure>
 <document>
        <xsp:logic>
            try
            {
                Resource res = null;
                String resStr = null;
                daeXmlDbApi daeApi = new daeXmlDbApi();
                ResourceIterator results;
                results = daeApi.getArticleSection("1").getIterator();
                while (results.hasMoreResources())
                {
                    res = results.nextResource();
                    <contents><xsp:expr>
(String)res.getContent()</xsp:expr></contents>
                }
            }
            catch(Exception e)
            {
            }
        </xsp:logic>
 </document>
</xsp:page>
Here you have <document/> as root element.

daeAPI is a API created by me to access to an XINDICE database that contains
XML following the current syntax:
<article>
  <title></title>
  <text></text>
  <image></image>
</article>
----------------------------------------------------------------------------

Transformer code
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:output indent="no" method="html" omit-xml-declaration = "yes" />

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

    <xsl:for-each select = "/article" >

                    <titulo><xsl:value-of disable-output-escaping = "yes"
select = "/title" /></titulo>
                    <imagem><xsl:value-of disable-output-escaping = "yes"
select = "/image" /></imagem>
   </xsl:for-each>

</xsl:template>

</xsl:stylesheet>
Here you match on <contents/> as root element. Try to remove the line 
<xsl:output/> or at least make it correct: you don't want html as result 
of this transformation. Furthermore does the XSP code return XML or a 
string of the database content, that should be XML. Fix it there. Don't 
use disable-output-escaping.

and the problem is that what i get in the view source of the browser is
something like,
&lt;?xml version="1.0"?&gt;
&lt;article id="1" rating="2" sectionid="1"
xmlns:src="http://xml.apache.org/xindice/Query"; src:col="/db/daeDocuments"
src:key="1"&gt;
        &lt;title&gt;Titulo com rating 2&lt;/title&gt;
    &lt;text&gt;Texto&lt;/text&gt;
&lt;/article&gt;&lt;?xml version="1.0"?&gt;
&lt;article id="2" rating="1" sectionid="1"
xmlns:src="http://xml.apache.org/xindice/Query"; src:col="/db/daeDocuments"
src:key="2"&gt;
                                &lt;title&gt;Titulo do artigo com rating igual a 
1&lt;/title&gt;
                                &lt;text&gt;texto do artigo com rating igual a 
1&lt;/text&gt;
                                &lt;image&gt;img1.jpg&lt;/image&gt;
&lt;/article&gt;&lt;?xml version="1.0"?&gt;
&lt;article id="3" rating="2" sectionid="1"
xmlns:src="http://xml.apache.org/xindice/Query"; src:col="/db/daeDocuments"
src:key="3"&gt;
                                &lt;title&gt;Titulo do artigo com rating igual a 
2&lt;/title&gt;
                                &lt;text&gt;texto do artigo com rating igual a 
2&lt;/text&gt;
                                &lt;image&gt;img1.jpg&lt;/image&gt;
                        &lt;/article&gt;&lt;?xml version="1.0"?&gt;
&lt;article id="4" rating="2" sectionid="1"
xmlns:src="http://xml.apache.org/xindice/Query"; src:col="/db/daeDocuments"
src:key="4"&gt;
                                &lt;title&gt;Titulo do artigo com rating igual a 
2&lt;/title&gt;
                                &lt;text&gt;texto do artigo com rating igual a 
2&lt;/text&gt;
                                &lt;image&gt;img1.jpg&lt;/image&gt;
                        &lt;/article&gt;
and i con't parse it in my transformer.

If anyone could give a look at the code and see what i am doing wrong i
would apreciate it :)
Thanks id advance
