problem simply stated

[S lakum]

Hi,
I just need to know how to move from node 'table-name' to node 'data-element', to node 'column-name'
My purpose here is to get the nodevalue of 'column-name' when i know the 'table-name' nodevalue(simply put- i need the column names of a table)
<table-name>hist_client</table-name>
<data-element>
<column-name>camp_id</column-name>
<column-name>ccl_id</column-name>
</data-element>
Help would be so appreciated!
Thanx

Please look at the below psuedo code to get an idea as to how to achieve your object using the DOM API.
I'm assuming that you have the <table-name> Node with you. The following is something what you need to do -
Node nextSibling = tableName.getNextSibling();
// make sure that this is an element node
if(nextSibling.getNodeType == nextSibling.ELEMENT_NODE)
{
if("data-element".equals(nextSibling.getNodeName())
{
// get the child nodes using getChildNodes()
// loop on the list of child nodes
// make sure that they are element nodes
// make sure their name is "column-name"
// AS SHOWN ABOVE
Node columnNameTextNode = columnNameElementNode.getFirstChild();
String wantedColumnName = columnNameTextNode.getNodeValue();
}
.........

Please look at the following link for more details on the DOM spec.

Hi Jayadev,
Thanks for ur help.
But I'm not able to work out the solution you've given. This is my DTD structure:
<!ELEMENT table-name (#PCDATA)>
<!ELEMENT data-element (column-name)+>
<!ELEMENT column-name (#PCDATA)>
when I'm comparing:
nextSibling.getNodeType==nextSibling.ELEMENT_NODE
i get the first as 1 and other as 3rd, ie text and element. Have I defined the dtd wrong?
Thanx
