JDOM,
 I've found the problem and it happens to be with JDOM itself.
If you read in an XML document into JDOM and then output it to a new
file without modifying the structure of the XML Document while in JDOM,
it adds extra characters to the file. Here's an example:

Here is my document as is on file:

<?xml version="1.0" encoding="UTF-8"?>
<!--DBPirate Configuration File-->
<dbpirate>
 <connections>
   <connection>
     <name>Oracle</name>
     <user>cbuser</user>
     <password>cbpass</password>
     <hostname>localhost</hostname>
     <port>1521</port>
     <timestamp>345678</timestamp>
     <class>org.mysql.jdbc.Driver</class>
     <url>jdbc:mysql@(protected)>
     <sid>cookbook</sid>
   </connection>
   <connection>
     <name>MySQL</name>
     <user>scott</user>
     <password>tiger</password>
     <hostname>localhost</hostname>
     <port>1521</port>
     <timestamp>12345888</timestamp>
     <class>oracle.jdbc.OracleDriver</class>
     <url>jdbc:oracle:thin@(protected)>
     <sid>orcl</sid>
   </connection>
 </connections>
</dbpirate>

And here it is after reading it into JDOM and then directly writing it
back out to another file without modifying it:

<?xml version="1.0" encoding="UTF-8"?>
<!--DBPirate Configuration File-->
<dbpirate>

 
<connections>
 
   
  <connection>
   
     
   <name>Oracle</name>
   
     
   <user>cbuser</user>
   
     
   <password>cbpass</password>
   
     
   <hostname>localhost</hostname>
   
     
   <port>1521</port>
   
     
   <timestamp>345678</timestamp>
   
     
   <class>org.mysql.jdbc.Driver</class>
   
     
   <url>jdbc:mysql@(protected)>
   
     
   <sid>cookbook</sid>
   
   
  </connection>
 
   
  <connection>
   
     
   <name>MySQL</name>
   
     
   <user>scott</user>
   
     
   <password>tiger</password>
   
     
   <hostname>localhost</hostname>
   
     
   <port>1521</port>
   
     
   <timestamp>12345888</timestamp>
   
     
   <class>oracle.jdbc.OracleDriver</class>
   
     
   <url>jdbc:oracle:thin@(protected)>
   
     
   <sid>orcl</sid>
   
   
  </connection>
 
 
</connections>


</dbpirate>


You can see my dilemma. It messes everything up when I try to delete a
portion of the document and then recreate it as needed and then output
it to a file. Anyone got any idea why this happens and how to fix it?
Thanks, Jeremy

JDOM,
 I’m trying to clear all nodes of a particular type so here is my
code:

Try
{
 SAXBuilder builder = new SAXBuilder();
 InputStream ins =
ClassLoader.getSystemResourceAsStream("testlogins.conf"); // was
dbpirate.conf
 Document doc = builder.build (ins);
 Element rootElement = doc.getRootElement();
 Element connElement = rootElement.getChild("connections");
 List children = connElement.getChildren("connection");
 Iterator iterator = children.iterator();
     
 rootElement.getChildren("connections").clear();
 rootElement.addContent(new Comment("Testing"));
 rootElement.addContent(new Element("connections"));
 try
 {
   XMLOutputter outputter = new XMLOutputter(" ", true);

 
   outputter.output(doc, System.out);
 }
 catch (java.io.IOException e)
 {
   e.printStackTrace();
 }
}

and I get output like this:

<?xml version="1.0" encoding="UTF-8"?>
<!--DBPirate Configuration File-->
<dbpirate>

 

<!--Testing-->
<connections />
</dbpirate>

You’ll notice about 3 lines of white space before the comment in the
<dbpirate> element. Is there any way to get rid of this or a better way
to get rid of nodes so that I can keep the white space out? Thanks,
