    xml node attributes are automatically being converted to lower case

    Hi,

    I am new to hacking javascript and this forum.

    I am trying to build a jsTree engine that parses an XML file, allows the user to modify the attribute values and then write this back to the server.

    I have building the function across several different scripts to get a understanding if what's going on.

    I am currently having an issue with the case of an attribute when I break out my xml node list. It always seems to be automatically set to lowercase.

    On the w3schools site I found this property styles.textTransform = "none", but I cant seem to apply it, in the correct place (see comments for where I tried).

    Is this what I should be using?

    I have attached my example code, it should be a complete example. It should produce an output that looks like the following,

    Starting here
    .OBJECTS.PGEXE1.REF.enablecomms="0"
    .OBJECTS.PGEXE1.REF.objtype="pglite"
    .OBJECTS.PGEXE1.REF.objectstate="initial"
    .OBJECTS.PGEXE1.REF.startupsleep="10"
    .OBJECTS.PGEXE1.REF.COMMAND.targetid="1"
    ......
    .OBJECTS.PGEXE1.REF.COMMAND.COMMS.STATUSREBOOT.pgcontroller=""
    .OBJECTS.PGEXE1.REF.COMMAND.COMMS.STATUSREBOOT.rebootcount="0"
    .OBJECTS.PGEXE1.REF.COMMAND.COMMS.STATUSREBOOT.rebootenable="1"
    .OBJECTS.PGEXE1.REF.COMMAND.COMMS.STATUSREBOOT.rebootthreshold="3"
    .OBJECTS.PGEXE1.REF.COMMAND.COMMS.STATUSREBOOT.reboottimeout="0"

    Ending here

    I am using Chrome as my browser, is there a way I can search all the properties of the xml2 variable, using the inbuilt debugging features?

    thanks

            html.push('+++'+$(this).attr()+ '<br>');
            } else {
              if(this.attributes.length > 0){
                //html.push('==='+this.nodeName + ': ' + this.attributes.length + ' ~ <br>');
                for( var iCnt = 0; iCnt < this.attributes.length; iCnt++){
                  //this.attributes[iCnt].nodeName.styles.textTransform = "none";
                  //this.textTransform = "none";
                  //html.push(printString + iCnt + '  ' + this.attributes[iCnt].nodeName + ' ' + this.attributes[iCnt].nodeValue + ' ~ <br>');
                  html.push(printString + '.' + this.attributes[iCnt].nodeName + '="' + this.attributes[iCnt].nodeValue + '"<br>');
                }
              }
              traverse(this, printString);
            }
          } 
       });
    }
    
    
    function createPage(obj) {
      html.push('Starting here');
      html.push('<br>');
    	
      //xml2.styles.textTransform = "none";
    
      traverse(xml2, '');
    	
      html.push('<br>Ending here');
      html.push('<br>');
      $('body').append(html.join(""));
    }
    window.onload = createPage();
    </script>
    </body>
    </html>

    I appear to have solved this by actually treating the string as XML. I am not sure how it was being treated before

    Code:
    function createPage(obj) {
      html.push('Starting here');
      html.push('<br>');
      
      if (window.DOMParser)
        {
        parser=new DOMParser();
        xmlDoc=parser.parseFromString(xml2,"text/xml");
        }
      else // Internet Explorer
        {
        xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async=false;
        xmlDoc.loadXML(xml2); 
        } 
    
      traverse(xmlDoc, '');
    	
      html.push('<br>Ending here');
      html.push('<br>');
      $('body').append(html.join(""));
    }
    The output looks much better

    .root.objects.pgExe1.REF.enablecomms="0"
    .root.objects.pgExe1.REF.objType="pglite"
    .root.objects.pgExe1.REF.objectState="initial"
    .root.objects.pgExe1.REF.startupSleep="10"
    .root.objects.pgExe1.REF.command.TargetId="1"
    .root.objects.pgExe1.REF.command.buoyId="001"
    .root.objects.pgExe1.REF.command.dspExePath="../v2.13/pg_dsp.out"
