[xml] XML newbie question

["Gopi Rajagopal" <gopi_rajagopal hotmail com>]

Hello,

I am trying to generate a XML file that corresponds to a DTD and which looks 
like this:

<!DOCTYPE cfgdata SYSTEM "1ca.dtd">
<config>
<!-- Host data -->
 <host>
    <hname>
      <hcmnd1>uname</hcmnd1>
      <hostname>solhost</hostname>
      <osname>Solaris</osname>
      <osver>10</osver>
    </hname>
    <proc>
      <hcmnd2>psrinfo</hcmnd2>
      <procname>Sparc sun4u</procname>
    </proc>
 </host>
...
...
</config>

My C code is as follows:
....
   xmlresp = xmlNewDoc ("1.0");

   node = xmlNewDocNode(xmlresp, NULL, "config", NULL);
   xmlCreateIntSubset(xmlresp, "config", NULL, "1ca.dtd");
   xmlresp->children = node;


   hchild = xmlNewChild (node, NULL, "host", NULL);
   hchild1 = xmlNewChild (hchild, NULL, "hname", NULL);
   hchild2 = xmlNewChild (hchild, NULL, "proc", NULL);

   xmlSetProp(hchild1, "hcmnd1", hostdata->command1);
   xmlSetProp(hchild1, "hostname", hostdata->hname);
   ...
   ...
  xmlSetProp(hchild2, "hcmnd2", hostdata->command2);
  xmlSetProp(hchild2, "procname", hostdata->procname);
  ...
  ...

  When I compile this program and run it, the xml generated is as follows:

<?xml version="1.0"?>
<config><host><hname hcmnd1="uname" hostname="solhost" osname="Solaris" 
osver="10"
/><proc hcmnd2="psrinfo" procname="sparcv9"/></host></config>

My question is this:

Why is my opening tag wrong and my closing tag missing?
Why do I see
<hname hcmnd1="uname" hostname="solhost" ... />
instead of
<hname> hcmnd1="uname" hostname="solhost" ...</hname>

Thanks

Gopi
