Re: [xsl] How to convert a whold result tree to a string?

[Joerg Heinicke <joerg.heinicke@xxxxxx>]

If the XML fragment is the input, the data type is "node set". If you 
use string() on a node set as in your example template, the result will 
be the concatenation of all descendant text nodes (in your case only " 
kkkk"). Hmm, now it's difficult to guess, what you really want. Not a 
node set, but a string "<test>...</test>"? But why? You can't "operate" 
on a string. But if you really want:

<xsl:template match="*">
  <xsl:text/>&lt;<xsl:value-of select="name()">
    <xsl:apply-templates select="@*"/>
    <xsl:text>&gt;</xsl:text>
    <xsl:apply-templates select="node()"/>
  &lt;/<xsl:value-of select="name()">&gt;
</xsl:template>

<xsl:template match="@*">
  <xsl:text> </xsl:text>
  <xsl:value-of select="name()"/>
  <xsl:text>="</xsl:text>
  <xsl:value-of select="."/>
  <xsl:text>"</xsl:text>
</xsl:template>

You can add further templates e.g. for comments and so on. If you only 
want a HTML view like IE offers, have a look at 
http://cvs.apache.org/viewcvs.cgi/xml-cocoon2/src/webapp/samples/common/style/xsl/html/simple-xml2html.xsl.
