string.search() function cannot parse string from XML response

Question

I'm using someresponse.getBody(); to store the XML response I'm getting back from a webservice. When I pass this to the below function, it's not able to be parsed corrected using search() or indexOf(). Both return a start and end pos of 10 and -1.

However, when I pulled the body of the response from the execution logs and hard coded the variable with that value. When I pass that value to the same function, it is processed as I expect.

This looks to be a format issue. Any idea what I can do here? I'm restricted to just using Javascript or NetSuite API's and the code runs server side.

I call the function using: var xmlCCConnote = getValue('CCConnote', response);

function getValue(tag,xmlString){
    var value;  
    var tempString;  
    var startTag,endTag;  
    var startPos,endPos;  
    startTag = "<"+tag+">";  
    endTag = "</"+tag+">";  
    tempString=xmlString;
    startPos = tempString.indexOf(startTag) + startTag.length;
    nlapiLogExecution('DEBUG', 'startPos = ', startPos);
    endPos = tempString.indexOf(endTag);
    nlapiLogExecution('DEBUG', 'endPos = ', endPos);
    value = tempString.slice(startPos,endPos);  
    return value;  
}

Answer 1

The xmlstring I was passing into the function was escaped. The following fixed the issue:

startTag = '<'+tag+'>';
endTag = '</'+tag+'>';
