Node Types

4.4 Node Types

XPath recognizes only the following types of nodes:
- Root
- Element

- Processing instruction
The other types of nodes are assumed to be already processed into the DOM tree.

node()	any node of any type

/	root

*	any element node

@*	any attribute node

text()	any text node

comment()

processing-instruction()
processing-instruction(’target’)

<article title="red"
         canvas="yellow">
  <section>
    <title>First
       section</title>
    <sentence>Some
       text.</sentence>
    <sentence>More
       text.</sentence>
    
    <?pi a?>
    <?pia b?>
  </section>
  <ns:appendix xmlns:ns="none"/>
</article>

//*/text()	First section Some text. More text.

//comment()	comment

//processing-instruction()	a b

//processing-instruction(’pi’)	b

The test program can be employed for the above examples (it requires java 5.0)
