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

[Ladhani, Dilip]

Thanks Kevin,
 
That seems to be a good strategy. 
I will definitely use it if there is no "getbyTagName()"" kinda method. Appreciate the quick response.
I am not worried about an element not being present as the vendor has a standadized xml.
 
 
Don't you think we should have a helper method like this.

	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.
