Need help with command - trying to target selected html in document

Question

Hi,
I am very new to working with JS. I can do simple stuff but when it comes to manipulating the dom, I don't know very much. So, I am trying to develop this command for Dreamweaver that will find all occurances of an abbreviation. Ex. GOC (Government of Canada) and wrap the text with <abbr> tags that include the title attribute. I have been using the change case example on the web that details how to go about setting up a DW command.
My JS file looks like this:
function canAcceptCommand(){
    var theDOM = dw.getDocumentDOM(); // Get the DOM of the current document
    var theSel = theDOM.getSelection(); // Get start and end of selection
    var theSelNode = theDOM.getSelectedNode(); // Get the selected node
    var theChildren = theSelNode.childNodes; // Get children of selected node
    return (theSel[0] != theSel[1] && (theSelNode.nodeType == Node.ELEMENT_NODE
    || theSelNode.hasChildNodes() && (theChildren[0].nodeType ==
    Node.ELEMENT_NODE)));
function abbr(){
  var theDOM = dw.getDocumentDOM();
          // Get the outerHTML of the HTML tag (the entire contents of the document).
          var theDocEl = theDOM.documentElement;
          var theWholeDoc = theDocEl.outerHTML;
          //while the position of a double space is not equal to -1, so there is one
          while(theWholeDoc.search("FSWEP") != "-1"){
                    //use reg exp to replace all spaces, which is useful for processing multiple lines at once
                    theWholeDoc = theWholeDoc.replace(/(FSWEP)/g, "<abbr>ASAP<\/abbr>");
          //loop back around until there are no double spaces
          theDocEl.outerHTML = theWholeDoc;
          theDOM.formatRange(0, theWholeDoc.length);
          window.close(); // close extension UI
In it's current state, it will do a replacement of FSWEP anywhere it shows up in the document. What I need it to do is only replace those occurances that are part of the selected HTML block and are part of a text node.
If there is anybody out there who can help me with this, I would really appreciate any assistance you might provide. At a very minimum, could you point me to some helpful resources that will help me figure out how to target chuncks of code in a DW HTML file.
Thanks,
Rob
