Default passing attribute info while traversing nodes

I imagine this is really easy, but I can't seem to figure things out. I'm using code from Chapter 11 of Professional ASP 3.0 to build this page. What I'm trying to do is build SQL statements from an XML file, but one pieces of the data that I need to be put in the statements is an attribute value of the node's parent.

I also want to know how I can determine the type of data, if it's string or integer, so that I can properly build the SQL statements.

Here's the code as is:

function parseXML()
  // check there were no parsing errors
  var domXMLData = dsoData;
  if (domXMLData.parseError.errorCode != 0)
    alert('Invalid XML file: ' + domXMLData.parseError.reason);

  // traverse the nodes
  txtData.innerHTML = showChildNodes(domXMLData, 0);

function showChildNodes(nodNode, intLevel)
  var strNodes = '';
  var intCount = 0;
  var intNode = 0;
  var nodAttrList;

  // check there are some attributes
  nodAttrList = nodNode.attributes;
  if (nodAttrList != null)
    intCount = nodAttrList.length;
    if (intCount > 0)
      strNodes += 'INSERT INTO Members (';

      // for each attribute, display the attribute information
      for (intAttr = 0; intAttr < intCount; intAttr++)
        strNodes += nodAttrList(intAttr).nodeName + ',';

      strNodes += ')';
      strNodes = strNodes.replace(",)",")");
      strNodes += ' VALUES (';

      // for each attribute, display the attribute information
      for (intAttr = 0; intAttr < intCount; intAttr++)
        strNodes += nodAttrList(intAttr).nodeValue + ',';

      strNodes += ')';
      strNodes = strNodes.replace(",)",")");
      strNodes += '<br>';

  // check for any child nodes
  intCount = nodNode.childNodes.length;
  if (intCount > 0)
    // for each child node, display the node, attributes and its child node information
    for (intNode = 0; intNode < intCount; intNode++)
      strNodes += showChildNodes(nodNode.childNodes(intNode), intLevel + 1);

  return strNodes;

So, I'm getting a nice little output so far that looks like this:

INSERT INTO Members (name,title,level,gender,species,xp_passed_up,num_ vassals) VALUES (Silver Dragon,Count,50,Male,Lugian,0,7)
INSERT INTO Members (name,title,level,gender,species,xp_passed_up,num_ vassals) VALUES (Mithoron,Baron,50,Male,Tumerok,165768770,7)

What I need to figure out is how to make it do this:

INSERT INTO Members (name,title,level,gender,species,xp_passed_up,num_ vassals,patron_name) VALUES ('Silver Dragon','Count',50,'Male','Lugian',0,7,null) <-- This guy is the topmost person
INSERT INTO Members (name,title,level,gender,species,xp_passed_up,num_ vassals,patron_name) VALUES ('Mithoron','Baron',50,'Male','Tumerok',165768770, 7,'Silver Dragon')

If you didn't catch it, I just added one more field, "patron_name", to the list of INSERT fields and need the "name" attribute from the parent passed on to the child record so it knows what to put in that field.

Hi Ashley,

Each node has a "parentNode" attribute which you can use to get at the attribute you want. OTMH I think the syntax goes like this:

nodNode.parentNode.attributes.getNamedItem("name") .text
