RE: Lotus XSL extensions

["Kevin Jones" <kevinj@xxxxxxxxxxx>]

Scott,

thanks for the posts - I discovered my problem (which may be a feature of
the XSL parser)

I had this
<xsl:stylesheet
	...
      xmlns:lxslt="http://xsl.lotus.com";

as my namespace definition - I should have had this

<xsl:stylesheet
	...
      xmlns:lxslt="http://xsl.lotus.com/";

Spot the difference - it took me a while!

You need the trailing / to get script to work (everything else works fine).

Now another question - how do I get at a node value

I have some XML which looks like this

<weather>
  <city>
    <name>London</name>
    <temperature>55</temperature>
  </city>
...

and xsl -

  <xsl:template match="temperature">
    <td>
        <xsl:value-of select="temp:convert(.)"/>
    </td>
  </xsl:template>


  <lxslt:component prefix="temp" functions="convert">
    <lxslt:script lang="javascript">

CDATA[	
      function convert (nodes) 
      {
        if (nodes.getLength() > 0)
        {
          node = nodes.item(0);
          returnVal = ''+node.getNodeValue();
        }
        else
        {
          returnVal = "4242";
        }
        return returnVal;
      }
    ]]>
    </lxslt:script> 
  </lxslt:component>


but node.getValue returns null.

Any idea? Scott?

Sorry for the long post - 

Kevin

Kevin, here is an example:

==== input xml ====

<?xml version="1.0"?>

<doc>
<?a-pi some data?>
</doc>

=== xsl ===
<?xml version="1.0"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/XSL/Transform/1.0";
                xmlns:lxslt="http://xsl.lotus.com/";
                xmlns:extn1="http://foo.com";
                extension-element-prefixes="extn1">

<lxslt:component prefix="extn1" functions="getPIData">
  <lxslt:script lang="javascript">
    <![CDATA[
      function getPIData(nodes)
      {
        if (nodes.getLength() > 0)
        {
          node = nodes.item(0);
          returnVal = node.getData();
        }
        else
        {
          returnVal = "";
        }
        return returnVal;
      }
    ]]>
  </lxslt:script>
</lxslt:component>

  <xsl:template match="/">
    <out>
      <xsl:value-of
select="extn1:getPIData(doc/processing-instruction('a-pi'))"/>
    </out>
  </xsl:template>

</xsl:stylesheet>

The type passed into the function is a com.lotus.xpath.MutableNodeListImpl,
which implements the NodeList interface (but which is not a true NodeList
since the nodes it holds are not reparented, and it is not owned by an
element).
