Re: [xsl] checking sequence inside processing-instruction

["Ganesh Babu N" <nbabuganesh@xxxxxxxxx>]

Dear All,

I am testing the saxon:get-pseudo-attribute() function in my xslt 1.0
style sheet to generate the HTML view.

My processing-instruction as follows:

<?PAGEBREAK id="PAGE0001" number="i"?>

I want to display the value in in the number attribute in the HTML view

My XSL is as follows:

<xsl:template match="processing-instruction('PAGEBREAK')">
<p><xsl:value-of select="saxon:get-pseudo-attribute('@number')"/></p>
</xsl:template>

this XSL is not generating any info related to number information.
even i tried with the @id then it is displaying the following message:

Warning: on line 162 of file:/D:/ganesh-schemas/xml/gae.xsl:
  The attribute axis starting at a processing-instruction node will never select
 anything

Please help me in getting the correct result.

Regards,
Ganesh
