Dear friends
 I am in big problem with geting index of a children. I am using JDOM parser. My XML document's format is like as follows----

<names>
  <name>
     <first>Hassanur</first>
     <last>Rahman</last>
  </name>
  <name>
     <first>Mofizur</first>
     <last>Rabbani</last>
  </name>
</names>


I can't get the index of 'name' children. I need this index to insert and delete operation in JDOM parser. Somebody please help me

Hassanur,

one thing you have to bear in mind is that when inserting/deleting in any DOM parser, the index values will change, so if you're doing this in a FOR loop, and you do an insert and on the next iteration you delete, you're pretty much not doing anything, not to mention if you do a delete, you'll get an out of bounds error when trying to reference what you thought was your last node.

that said, I don't know the specifics about JDOM, but if you do:

documentElement.selectNodes ("names/name")

you'll get a reference to all the names node, now if you do

myNodes = documentElement.selectNodes ("names/name[first='Hassanur']")

you'll get a reference to all the name nodes whos first text = 'Hassanur'
then you get the first one by doing myNodes.item(0)

Hope this helps, though I'm not sure if it answers your question


thanks

if I add an attribute in name node like <name id="1"> or a chile node under every name node like "<id>1</id>" and this id will work as a primary key then how can I get the corresponding name node's index in JDOM parser. This is my original problem and for your kind information I am weak in Java coading.
