Does JAXP support XSLT 2.0

Question

1. My ${java.home} is C:\\Program Files\\Java\\jdk1.7.0_51.
2. I extracted saxonHE9-6-0-6J.zip in C:\\Program Files\\Java\\jdk1.7.0_51\\jre\\lib\\ext
3. and add saxonhe9.jar to my classpath variable.

4. Then I created a jaxp.properties file under C:\\Program Files\\Java\\jdk1.7.0_51\\jre\\lib and add the following lines:

   javax.xml.transform.TransformerFactory = net.sf.saxon.TransformerFactoryImpl javax.xml.xpath.XPathFactory","net.sf.saxon.xpath.XPathFactoryImpl

For testing I use in my stylesheet the following lines

<xsl:for-each select="//*[@type='Usage']/@name">
  <xsl:value-of select="." separator="', '"/>
</xsl:for-each>

But the output of

StreamResult result = new StreamResult(System.out);
transformer.transform(source, result);

is a string withoput commas.

Answer 1

JAXP is an interface, not an implementation; and it embraces schema processing and XPath processing as well as XSLT processing.

There are several implementations of the JAXP transformation interface, including the built-in XSLT processor in the JDK, the two versions of Xalan that come in the Xalan-J product from Apache, the Oracle XSLT processor, and Saxon. Of these the only one that supports XSLT 2.0 is Saxon.

Answer 2

I think you simply want <xsl:value-of select="//*[@type='Usage']/@name" separator=", "/> instead of

<xsl:for-each select="//*[@type='Usage']/@name">
  <xsl:value-of select="." separator="', '"/>
</xsl:for-each>

as the latter obviously will never output a separator given that you have the value-of inside of the for-each that ensures that . is a single item for the value-of .

Online sample at http://xsltransform.net/6qVRKx4 outputs name 1, name 3 for input sample

<root>
    <foo type="Usage" name="name 1"/>
    <foo type="Nonsense" name="name 2"/>
    <foo type="Usage" name="name 3"/>
</root>
