[jdom-interest] direct access to an arbitrary element----can I do this??

[Kevin.Bedell at sunlife.com]

I'd do that like this:

            Element     root = doc.getRootElement();

            Element     pqr_Element = root.getChild("def").getChild("ghi").getChild("mno").getChild("pqr");
            Element     rst_Element = root.getChild("def").getChild("ghi").getChild("mno").getChild("rst");
            Element     uvw_Element = root.getChild("def").getChild("ghi").getChild("mno").getChild("uvw");

Not sure about XPATH support - it may be cleaner. Not sure if it's supported.

Be careful - if one of the intermediate getChild() calls returns null, you'll throw NullPointerException.

FWIW-
Kevin

Hey guys,

I have a simple operation to do. I am not sure how I can do this using
Jdom. I have an XML that I get from on of our vendors. It kinda looks like
this
<?xml version="1.0" encoding="ISO-8859-1" ?>
<abc>
     <def>
           <ghi>
               <jkl>
                      <mno>
                                <pqr>1111</pqr>
                                <rst>2222</rst>
                                <uvw>3333</uvw>
                       </mno>
               </jkl>
           </ghi>
     </def>
</abc>

Can I directly read the data in the tags pqr, rst, uvw etc or do I have to
keep doing getchild() until I reach the tag mno to do anything meaningful.
In short how can I access a tag somewhere in the xml tree by tag name.


Thanks, Your help is appreciated.
