Doubt in XPath Axis

[senthil rajan]

Hi Frnds,

I need to calrify a problem. The following two Axis gives the same result.

child::*
descendant::*

My question is, as it gives the same results, why do we have two separate Axis .Is there any other difference?

Thanks,
Senthil.

Lets take an example :-)

  
<book>
  <title>Understanding Child and Descendant ;-) </title>
  <name> 
          <last> peter </last>
          <first> Jhon </first>
  </name>
  <price>100</price>
</book>
 

And lets assume that we are considering the book node to be the selected node

child::*

will select only <title>, <name>, <price>

Originally posted by senthil rajan:


descendant::*

will select <title>, <name>, <first>, <last>,<price>

"child" will select only immediate child elements (that are directly under book element)

"descendant" will slect all elemnts under <book> irrespective of how deep they are nested !!

Hope that helps
