Re: msxsl:script and selectSingleNode problem

Your Javascript function is:

> function init(itemNode)
> {
> if( !itemNode.length) return "";
>
> var val = itemNode.item(0).selectSingleNode('book');
>
> //var val = itemNode.item(0).firstChild;
>
> if(val!=null)
> return val.text;
>
> return "Error";
> }


and it is called from:

> <xsl:template match="/">
> <xsl:call-template name="callInit">
> <xsl:with-param name="itemNode" select="."/>
> </xsl:call-template>
> </xsl:template>

This statement:

> var val = itemNode.item(0).selectSingleNode('book');

evaluates the XPath expression "book" and assigns the result to the variable
"val".

because "itemNode" is the root node (/), the XPath expression will not
select anything. The only element child of the root is the "items" element.

Change:

> <xsl:with-param name="itemNode" select="."/>

to:

  <xsl:with-param name="itemNode" select="*"/>


Now you'll get the wanted result.

is printing "Error". It seems like it is not able to get to "book" node when
I use selectSingleNode("book"). But variety is when ever I access it as
.firstChild, it is recognizing  the node  and printing the correct value.
