 Bob,
Using our latest production release 2.0.2.7,
the following test program does what you're
trying to do, but I get the correctly re-sorted
data formatted by the final XSLT stylesheet into
HTML with the order of the <a> cells sorted.
Hope this helps find what might be awry in your
environment. (P.S. If you've got a database, why
not let *it* do the ORDER BY instead of doing
DOM tree surgery?)
thanks.
import oracle.xml.parser.v2.*;
import org.w3c.dom.*;
import java.io.*;
public class Bob {
private static DOMParser dp = null;
private static XMLDocument getXML(String name) throws Throwable {
if (dp==null) dp = new DOMParser();
dp.parse(new FileInputStream(name));
return (XMLDocument)dp.getDocument();
}
public static void main(String[] args) throws Throwable {
// setup (overall question: Why not let database do the sorting?)
XMLDocument xmlsrc = getXML("Bob.xml");
XMLDocument xml2htmlsrc = getXML("xml2html.xsl");
XMLDocument bobsortsrc = getXML("identitysort.xsl");
XSLStylesheet xml2html = new XSLStylesheet(xml2htmlsrc,null);
XSLStylesheet bobsort = new XSLStylesheet(bobsortsrc,null);
XSLProcessor p = new XSLProcessor();
// remember <rowset> element
Node whereRowsetIs = xmlsrc.selectSingleNode("//rowset");
// Transform orig sort to get "sorted" <rowset> data.
DocumentFragment df = xmlsrc.transformNode(bobsort);
// Find the <rowset> in the sorted document
Node sortedRowset = ((XMLNode)df.getFirstChild()).selectSingleNode(".//rowset");
// Insert the new sorted <rowset> and remove the old one
whereRowsetIs.getParentNode().insertBefore(sortedRowset,whereRowsetIs);
whereRowsetIs.getParentNode().removeChild(whereRowsetIs);
// Transform original doc with surgically inserted sorted <rowset> to HTML
p.processXSL(xml2html,xmlsrc,System.out);
}
}
Produces the expected (sorted) HTML results of:
<html>
<body>
<table>
<tr>
<td>11</td>
<td>Bob</td>
</tr>
<tr>
<td>12</td>
<td>Steve</td>
</tr>
</table>
</body>
</html>
When fed the following three files:
<!-- Bob.xml -->
<resultset>
<rowset>
<row><a>12</a><b>Steve</b></row>
<row><a>11</a><b>Bob</b></row>
</rowset>
</resultset>
<!-- IdentitySort.xsl -->
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match='rowset'>
<xsl:copy>
<xsl:apply-templates select='row'>
<xsl:sort select='a' data-type='number'/>
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
<!-- xml2html.xsl-->
<xsl:stylesheet xmlns:xsl='http://www.w3.org/1999/XSL/Transform' version='1.0'>
<xsl:output method="html"/>
<xsl:template match="/">
<html><body><table>
<xsl:for-each select="//rowset/row">
<tr>
<td><xsl:value-of select="a"/></td>
<td><xsl:value-of select="b"/></td>
</tr>
</xsl:for-each>
</table></body></html>
</xsl:template>
</xsl:stylesheet>

Subject: inconsistent results from stylesheet
| I am using the Oracle XSLT processor to translate XML into HTML. My
| XML is pulled from an Oracle DB as a DOM document, then I apply my
| parsed XSL stylesheet. Works fine the first time.
|
| When the user requests that the results be sorted, I apply a second
| stylesheet with little more than an xsl:sort command to sort the data
| section of my document (all other nodes are simply copied from the
| source tree to the result tree). The sort operation leaves me with a
| document-fragment. I find the node in my original XML DOM document
| that matches the root of the sorted document-fragment and I replace
| that node with the sorted data.
|
| Then I re-apply my XML-to-HTML stylesheet again to the sorted data.
| But the second time I apply my stylesheet, it does not work.
|
| My XML looks like this:
| <RESULTSET>
| <COLUMNLIST>...</COLUMNLIST>
| <ROWSET>
| <ROW>
| <C1>...</C1>
| <C2>...</C2>
| <C3>...</C3>
| </ROW>
| ...
| </ROWSET>
| </RESULTSET>
|
| What could be simpler? I have a template for the data section that
| matches on the <ROWSET> tag.
|
| <xsl:template match="ROWSET">
| <xsl:message>
| Inside ROWSET template...
| </xsl:message>
| <xsl:for-each select="ROW[position() = ($SkipRows+1)]">
| ...
| </xsl:for-each>
| </xsl:template>
|
| The first time I apply my stylesheet, I see this message and I know
| that the template is being applied as expected. But the second time
| I apply this stylesheet, this template does not fire. Instead, I see
| the default template fire for the <ROWSET> node:
|
| <xsl:template match="*|/">
| <xsl:message>
| Applying templates from default "*|/" template,
| node:<xsl:value-of select="name()" />!!
| </xsl:message>
| ...
| </xsl:template>
|
| This puts a console message of:
| Applying templates from default "*|/" template,
| node:ROWSET!!
|
| I have worked around this problem by naming my "ROWSET" template and
| explicitly calling my ROWSET template from the "*|/" template as
| follows:
| <xsl:if test="name()='ROWSET'">
| <xsl:call-template name="insert-rowset"/>
| </xsl:if>
|
| This works, but shouldn't the template fire based on the
| match="ROWSET" attribute?
| <xsl:template match="ROWSET" name="insert-rowset">
| ...
| </xsl:template>
|
| Is this a bug in the Oracle processor?
|
| ..Bob.
