I have code that loops through a web service to pull information in, and inserts it into a master detail section.  I have filters on the master detail section to keep each inserted row organized and unique based upon id's.  Here is my code and I was wondering if there was any way I could speed this up.  Thanks for your input

 function getDefaultFindingsOS(elementID, summary)
{
       XDocument.View.DisableAutoUpdate();
    var recMasterTableCtrlID = "CTRL388";
    var ws = XDocument.GetDOM("GetDefaultFindings");
    ws.setProperty("SelectionNamespaces", "xmlns:dfs=\"http://schemas.microsoft.com/office/infopath/2003/dataFormSolution\" xmlns:ns4=\"http://test.com/\"");
    var oMasterTable = XDocument.DOM.selectSingleNode("/my:IC3/my:Enc");
    var iRow = XDocument.GetNamedNodeProperty(oMasterTable, "CTRL1083", 1);
    var curEnc = XDocument.DOM.selectNodes("/my:IC3/my:Enc/my:EncRepeat");
    var summaryField = curEnc.item(iRow-1).selectSingleNode(summary);    
    var Finding = ws.selectNodes("/dfs:myFields/dfs:dataFields/ns4:GetDefaultFindingsResponse/ns4:GetDefaultFindingsResult/ns4:WSDefaultFinding[ns4:ElementID='" + elementID + "'][ns4:Eye='OS']");
    var blankSpace = /\s+$/g;
    summaryField.text = summaryField.text.replace(blankSpace, "");
