XDK XSLT proccessor alternative

Question

Hi,
I'm using XSL transformation build in XDK, but there is a bug admitted by Oracle. They try to fix it but it takes too long.
My question is... Is there any alternative to XDK XSL processor? Something what can be called in PLSQL. ... Java, C++, whatever ?
Thanks.

Answer 1

From the XMLDB 11g Developers Manual:
XMLType instance can be transformed in the following ways:
- Using SQL function XMLtransform (or XMLType method transform()) in the database.
- Using XDK transformation options in the middle tier, such as XSLT Processor for Java.
XMLTRANSFORM and XMLType.transform():
Examples
The examples in this section illustrate how to use SQL function XMLtransform and XMLType method transform() to transform XML data stored as XMLType to various formats.
Example 10-1 Registering XML Schema and Inserting XML Data
This example sets up the XML schema and tables needed to run other examples in this chapter. (The call to deleteSchema here ensures that there is no existing XML schema before creating one. If no such schema exists, then deleteSchema produces an error.)
BEGIN
  -- Delete the schema, if it already exists; otherwise, this produces an error.
  DBMS_XMLSCHEMA.deleteSchema('http://www.example.com/schemas/ipo.xsd',4);
END;
BEGIN
-- Register the schema
DBMS_XMLSCHEMA.registerSchema('http://www.example.com/schemas/ipo.xsd',
'<schema targetNamespace="http://www.example.com/IPO"

DBURIType is described in Chapter 20, "Accessing Data Through URIs".
DROP TABLE stylesheet_tab;
CREATE TABLE stylesheet_tab(id NUMBER, stylesheet XMLType);
INSERT INTO stylesheet_tab
  VALUES (1,
          XMLType(
            '<?xml version="1.0" ?>
             <xsl:stylesheet version="1.0"
                             xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
               <xsl:template match="*">
                 <td>
                   <xsl:choose>
                     <xsl:when test="count(child::*) > 1">
                       <xsl:call-template name="nested"/>
                     </xsl:when>
                     <xsl:otherwise>
                       <xsl:value-of select="name(.)"/>:<xsl:value-of
                                                          select="text()"/>
                     </xsl:otherwise>
                   </xsl:choose>
                 </td>
               </xsl:template>
               <xsl:template match="*" name="nested" priority="-1" mode="nested2">
                 <b>
                   <!-- xsl:value-of select="count(child::*)"/ -->
                   <xsl:choose>
                     <xsl:when test="count(child::*) > 1">
                       <xsl:value-of select="name(.)"/>:<xsl:apply-templates
                                                          mode="nested2"/>
                     </xsl:when>
                     <xsl:otherwise>
                       <xsl:value-of select="name(.)"/>:<xsl:value-of
                                                          select="text()"/>
                     </xsl:otherwise>
                   </xsl:choose>
                 </b>
               </xsl:template>
             </xsl:stylesheet>'));
SELECT
  XMLtransform(x.xmlcol,
               DBURIType('/XDB/STYLESHEET_TAB/ROW
                            [ID=1]/STYLESHEET/text()').getXML()).getStringVal()
  AS result
  FROM po_tab x;
This produces the following output (pretty-printed here for readability):
RESULT
<td>
  <b>ipo:purchaseOrder:
    <b>shipTo:
      <b>name:Helen Zoe</b>
      <b>street:100 Broadway</b>

      <b>state:Wales</b>
      <b>country:UK</b>
      <b>zip:CF2 1QJ</b>
    </b>
    <b>billTo:
      <b>name:Robert Smith</b>
      <b>street:8 Oak Avenue</b>
      <b>city:Old Town</b>
      <b>state:CA</b>
      <b>country:US</b>
      <b>zip:95819</b>
    </b>
    <b>items:</b>
  </b>
</td>Example 10-3 Using XMLTRANSFORM and a Subquery to Retrieve a Style Sheet
This example illustrates the use of a stored style sheet to transform XMLType instances. Unlike the previous example, this example uses a scalar subquery to retrieve the stored style sheet:
SELECT XMLtransform(x.xmlcol,
    (SELECT stylesheet FROM stylesheet_tab WHERE id = 1)).getStringVal()
     AS result
   FROM po_tab x;Example 10-4 Using Method transform() with a Transient Style Sheet
This example uses XMLType method transform() to transform an XMLType instance using a transient style sheet:
SELECT x.xmlcol.transform(XMLType(
'<?xml version="1.0" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="*">
    <td>
    <xsl:choose>
      <xsl:when test="count(child::*) > 1">
        <xsl:call-template name="nested"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="name(.)"/>:<xsl:value-of select="text()"/>
      </xsl:otherwise>
    </xsl:choose>
    </td>
</xsl:template>
<xsl:template match="*" name="nested" priority="-1" mode="nested2">
    <b>
    <!-- xsl:value-of select="count(child::*)"/ -->
    <xsl:choose>
      <xsl:when test="count(child::*) > 1">
        <xsl:value-of select="name(.)"/>:<xsl:apply-templates mode="nested2"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="name(.)"/>:<xsl:value-of select="text()"/>
      </xsl:otherwise>
    </xsl:choose>
    </b>
</xsl:template>
</xsl:stylesheet>'
)).getStringVal()
FROM po_tab x;
So in short XMLTRANSFORM ;-) ?
