RE: [xsl] Re: Finding position of a node relative to the roo

This solution is more succinct and it works in the sablotron
configuration I have currently. I see why the parenthesis are necessary,
to keep referencing the movie nodes at a global level.

Thank you for your help!

instead of the parent node


Your problem is that in your code you have expressions like this:

    //movie[position() &lt;=  number($thisMany)]

When actually you want this expression instead:

    (//movie)[position() &lt;=  number($thisMany)]


Investigate this problem (e.g. look into the XSL FAQ) and try to
understand the difference between the two XPath expressions. This is a
FAQ about using the abbreviation //

So, you have to make just two changes in your code:

1. Change:

>       <xsl:for-each select="//movie[position() &lt;= 
> number($thisMany)]">


to:

     <xsl:for-each select="(//movie) [position() &lt;=
number($thisMany)]">


2. Change:

>       <xsl:for-each select="//*[name()='movie'][position() &gt; 
> number($thisMany)]">

to:

     <xsl:for-each select="(//*[name()='movie']) [position() &gt;
number($thisMany)]">



The corrected code now produces a nice 2-column table.
