RE: processing-instruction()

Thanks, Joerg. I still have the PIs in the output with the following
Stylesheet. I do have the
specific matchings for the PIs. I'm using xalan. Are PIs in node()? My
impression from a book is that node() only matches elements. 

Thanks.

       </xsl:copy>
  </xsl:template>
  
  <xsl:template match="processing-instruction('Eqn')">
      <!-- do nothing now -->
  </xsl:template>
  
  <xsl:template match="processing-instruction('Pub')">
      <!-- do nothing now, but want to keep -->
  </xsl:template>

processing-instruction() is included in node(), so if you do

<xsl:apply-templates select="node()" />

and if you have a template matching on node(), you don't need the special 
<xsl:apply-templates/> and <xsl:template/> for the processing instructions. 
If you remove every pi-stuff they will be simply copied to output. If you 
add a template matching on the special processing-instruction, this one will

not be copied to output.

Joerg
