Subject: Get the root node name

Hi All

I have the following xml
*************************************
<node cid="1" oid="2">
<node_name>India</node_name>
<node cid="11" oid="4">
<node_name>Maharashtra</node_name>

<node cid="22" oid="8">
<node_name>Mumbai</node_name>

<node cid="33" oid="8">
<node_name>Dadar</node_name>
</node>
*************************************
In this I want to retrieve the node_name at the root level which is India. But I do not want to retrieve by using relative path like ../node_name or ../../node_name as the number of sub nodes under some xml instance root node is not standard. In some cases the nodes could be 1 or 3 or 5.

What I want to do by processing (something like using ancestor ) get the topmost parent & then fetch the value for the same. I cannot use the parent or grandparent xpath command as this would fetch me only 1 or 2 nodes above & it would be rigid & not dynamic enough . So irrespective of any level in the hierarchy I want to fetch the topmost root node

Can someone help me in deriving a way to achieve the same

Regards

<xsl:value-of select="name(/*)"/>

Not sure if you're using xsl, but the xpath should work in most applications.

Hi ,

I tried quiet a few techinques but could not get the output as intended.

Here is the sample xml file which we get
*********************************

<node cid="1" oid="2">
<node_name>India</node_name>
<node cid="11" oid="4">
<node_name>Maharashtra</node_name>

<node cid="22" oid="8">
<node_name>Mumbai</node_name>

<node cid="33" oid="8">
<node_name>Dadar</node_name>
</node>
*********************************

Now when I am processing every node I need the reference to the root node everytime. Something like
when I m in "Dadar" I need to identify the top most root node value which is "India"

so its like

Root Parent is India for all the child elements under India.

Do post your thoughts

Perhaps:
<xsl:value-of select="/*//node_name"/>

If you're using apply-templates to process these nodes, you could have a parameter which keeps track of the 'root' node.

Hi James,

I tried this solution but it works only for the 1st parent.

Here is what my xml file looks like

****************************************
<node cid="11" oid="4">
<node_name>Maharashtra</node_name>

<node cid="22" oid="8">
<node_name>Mumbai</node_name>

<node cid="33" oid="8">
<node_name>Dadar</node_name>
</node> --------

****************************************

Now this is another node

<node cid="11" oid="4">
<node_name>Karnataka</node_name>

<node cid="22" oid="8">
<node_name>Bangalore</node_name>

<node cid="33" oid="8">
<node_name>MGRoad</node_name>
</node>

The problem is I am only getting Maharashtra as the topmost root for all the nodes where as in case of Karantaka, Bangalore & MGRoad the top most root node is Karnataka.
