include specific element with cinclude

["Schultz, Gary - COMM" <GS...@commerce.state.wi.us>]

I have cinclude working so that I can get all of the specific elements from
an XML file. What I have not found a way to do is get the 2nd, 3rd, 4th,
etc. element or get an element by attribute value. I have found nothing in
Cocoon wiki to explain how one uses cinclude to include only a part of the
XML file. 

For example, I can use the following to get all paragraph elements in an xml
file:

<cinclude:include xmlns:cinclude="http://apache.org/cocoon/include/1.0" 
  src="http://localhost/something.xml"
select="//*[local-name()='paragraph']/."/>

But what I want is to get a specific paragraph element from the file. Any
direction on this is greatly appreciated.

You need to be more precise in your xpath expression:

 //paragraph[@var='ABC123']

chooses all paragraphs with an attribute var that equals 'ABC123'.

 paragraph[1]

chooses the first occurence of paragraph.
