How to insert an xml-tree stored in a string?

[Hans-Guenter Stein <Ha...@siteos.de>]

How to insert an xml-subtree generated via some Java-functions into an
xml-document?

like:

    <xsp:logic>
     String aaa = "<a><a1>this is a1</a1><a2>this is a2</a2></a>";
    </xsp:logic>
    <xsp:expr>aaa</xsp:expr>

such that a subsequent processing instruction could work with the
inserted nodes

I actually used the util-template code :-)

...probably still too slow (for me)

Actually Hans-Guenther got it working... I doubt
this template does it faster! But, well, prove
me wrong and I'll be happy ;-)

You should look at the util taglib and the file
src/org/apache/cocoon/processor/xsp/library/java/util.xsl
in cocoon archive.

There is an XSP template written to include an
URI as DOM in a document. Using a string instead
of fetching an URI should be easy.

I got it working but the solution is rather slow (see code below)

I wonder whether there is a solution that works a little faster. Any ideas??

    <xsp:logic>
     // the mysql.showTableXML returns a string containing
     // the contents of a table enclosed in xml-tags
     String out=mysql.showTableXML("spiele");
    </xsp:logic>

    <xsp:expr>
      this.xspParser.parse(
        new InputSource(
          new StringReader(
     String.valueOf(out)
          )
        )
      ).getDocumentElement()
    </xsp:expr>

That's exactly what I asked for in another thread.
As far as I know now... You can't without parsing the
String by yourself.

You can

1)add a single node with "xspCurrentNode.appendChild()"
2)or add a tree you build up by yourself
3)or use use the cocoon parser to do so (I guess)

See the XSPSqlLibary.java how it works...
I'm trying on this, too, because I don't like
the approach to have the sql string in my pages.
I'm thinking of a bean doing this and giving back
a tree which represents the query result.
