RE: Convert String to (node-set)

Thank you so much, it works! (of course it does...). Now I am moving to the
next step. I am trying to integrate my XSL (with a Saxon extension
function) in my Java program which uses a the XALAN processor. I know I
should just switch everything to Saxon, unfortunately, I do not have
complete access now to do it.

So, the obvious Q is, how do I integrate a SAXON extension fn. when I want
to use XALAN (LAtest release, 2.0) from my JAVA program. This is what I
have tried so far:

XSL code snippets:

1. Eg.1
<xsl:stylesheet version="1.0" xmlns:xsl
="http://www.w3.org/1999/XSL/Transform"  xmlns:saxon="http://icl.com/saxon"
exclude-result-prefixes="saxon">

  <xsl:template match ="/">
   <xsl:value-of select="saxon:evaluate(some str)" />
  </xsl:template>
</xsl:stylesheet>

This works perfectly fine with the SAXON 6.1 processor from command line.
However, I get an error when I try to run it from XALAN.

2. Eg. 2
<xsl:stylesheet version="1.0" xmlns:xsl
="http://www.w3.org/1999/XSL/Transform"  xmlns:saxon="http://icl.com/saxon"
exclude-result-prefixes="saxon">

  <xsl:template match ="/">
   <xsl:value-of select="saxon:functions.Extensions.evaluate(some str)" />
  </xsl:template>
</xsl:stylesheet>

Same error as in 1.

3. Eg. 3
<xsl:stylesheet version="1.0" xmlns:xsl
="http://www.w3.org/1999/XSL/Transform"  xmlns:saxon
="http://icl.com/saxon.functions.Extensions" exclude-result-prefixes
="saxon">

  <xsl:template match ="/">
   <xsl:value-of select="saxon:evaluate(some str)" />
  </xsl:template>
</xsl:stylesheet>

same error as in 1 and 2.

4. Eg. 4
<xsl:stylesheet version="1.0" xmlns:xsl
="http://www.w3.org/1999/XSL/Transform"  xmlns:saxon
="xmlns:saxon=http://icl.com/saxon" exclude-result-prefixes="saxon">

  <xsl:template match ="/">
   <xsl:value-of select="saxon:evaluate(some str)" />
  </xsl:template>
</xsl:stylesheet>

same error as in 1,2,3 above.

Any suggestions? I know I need to make the proper reference to the
extension fn. from Xalan, but how?

Thanks for all the help.

I think you want something like:

>     <xsl:for-each select="$node/Node_path">
        <xsl:variable name="xpath" select="."/>
        <xsl:for-each select="$chandoc">
>       <xsl:text>The Value retrieved from doc 2 is:
> </xsl:text><xsl:value-of
> select="saxon:evaluate($xpath)" />
        </xsl:for-each>
>     </xsl:for-each>

The inner for-each is just to change the context node to the $chandoc
document, so that the evaluate() applies the path expression to this
document.
