xalan xsl

[thomas.porschberg]

Hi,
I have the following problem:
I want convert XML in the form:

<?xml version="1.0" encoding="UTF-8"?>
<dataset>

<row><value>1-String</value><value>2-String</value><value>3-String</value></row>

<row><value>r1-String</value><value>r2-String</value><value>r3-String</value></row>
</dataset>

to HTML for example

I wrote a small stylesheet:

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"/>
<xsl:template match="/">
<table border="1">
<xsl:apply-templates select="dataset/row"/>
</table>
</xsl:template>

<xsl:template match="dataset/row">
<tr>
<xsl:apply-templates select="value"/>
</tr>
</xsl:template>

<xsl:template match="value">
<td>
<xsl:value-of select='.'/>
</td>
</xsl:template>
</xsl:stylesheet>

The stylesheet works fine with my xsltproc.
The out put is:

<table border="1">
<tr>
<td>1-String</td>
<td>2-String</td>
<td>3-String</td>
</tr>
<tr>
<td>r1-String</td>
<td>r2-String</td>
<td>r3-String</td>
</tr>
</table>

However when I try to run this stylesheet with the Xalan library from
within a java application,
with a TransformerHandler I get from SAXTransformerFactory, the result
is only:

<table border="1"></table>

Can someone give me a hint ?

Your XML and XSLT are correct. Therefore the software is broken
and should be replaced with something that works.

I'd have to see the Java application. Make sure the source document is
being built as namespace-aware, with the namespace declaration attributes.

You may want to try your stylesheet with some of the simple drivers that
come with Xalan. If it works with those, compare them with your own code
and fix the latter.

The problem I have is that I programmed against the javax.xml.
interfaces.
In the code I say nowhere "take xalan".

The code looks like:

TransformerFactory transFact =
TransformerFactory.newInstance();

SAXTransformerFactory saxTransFact = (SAXTransformerFactory)
transFact;
TransformerHandler transHand = null;

transHand = saxTransFact.newTransformerHandler(new
StreamSource(xsltFileName));
transHand.setResult(new StreamResult(System.out));

javax.xml.transform.Result result =
new javax.xml.transform.stream.StreamResult(System.out );

StringArrayXMLReader saReader;
try {
saReader = new StringArrayXMLReader(transHand);
saReader.init();
saReader.parse(arr);
saReader.parse(arr2);
saReader.close();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

arr and arr2 are String-arrays.

I can run the code without xalan in my CLASSPATH and I get the wrong
result.
Apparently the SDK itself provides some xslt functionality.
The question is now how can I specify that xalan is used ?

When I run the example above without xsl-Stylesheet,

transHand = saxTransFact.newTransformerHandler();

I get my pure XML-output:

<?xml version="1.0" encoding="UTF-8"?>
<dataset><row><value>1-String</value><value>2-String</value><value>3-String</value></row><row><value>R1-String</value><value>R2-String</value><value>R3-String</value></row></dataset>
which is correct.

I tried the example from
http://www.topxml.com/java/articles/xslt/default.asp
with the 3 files: AbstractXMLReader.java CSVXMLReader.java
SimpleCSVProcessor.java

The example Example 5-9: csvToHTMLTable.xslt does not work when I
specify the stylesheet. It creates a output:

<table border="1"></table>

instead of a full table output.

Still any hint ?

It would help if the book's code wasn't broken. He's passing the
localname as "". That doesn't match SAX's design.

Start by changing all the SAX event calls to fix this -- eg, change
ch.startElement("","","line",EMPTY_ATTR);
to
ch.startElement("","line","line",EMPTY_ATTR);
and so on.

Moral: Don't assume that code is right just because it's been published.
That hopefully means it was tested on one implementation... but that
implementation may have been wrong, and I *have* seen code published
that wasn't tested at all.

Thanks a lot for your message ! It solved the problem and now I have
to read more about
the SAX design. And yes it is awkward to publish broken code as ad for
a book.
