Looping элементов XML по конкретному значению атрибута

В моей JavaScript я пытаюсь траверс XML элементы, которые имеют атрибут PlanId = «5» ONLY, а затем назначить переменные для каждого элемента плана к другим атрибутам, указанным ниже в моем коде цикла, однако я не могу получить только те элементы PlanId = "5" (LAST 5 lines) в моем XML выше. Любая помощь/направление будут оценены. Вот моя попытка цикла при получении на это:

planId = 5; 

for (var i = 1; i <= planIdCount; i++) { 

    // Get Plan attributes for affordability calculations 
    tierID = Provenir.getValue("/Data/Request/Plan[" +i+ "]/PlanId="+planId+"/@*[name()='TierId']"); 
    prov.log(0, "tierID: " + tierID); 
    tierMultiplier = Provenir.getValue("/Data/Request/Plan[" +i+ "]/PlanId="+planId+"/@*[name()='TierMultiplier']");    
    prov.log(0, "tierMultiplier: " + tierMultiplier); 
    config.Global_Variables.CalculatedAffordabilityLines[0].TierMultiplier.setValue(tierMultiplier); 
    monthlyRate = Provenir.getValue("/Data/Request/Plan[" +i+ "]/PlanId="+planId+"/@*[name()='MonthlyRate']"); 
    prov.log(0, "monthlyRate: " + monthlyRate); 
    config.Global_Variables.CalculatedAffordabilityLines[0].MonthlyRate.setValue(monthlyRate); 
    roundDown = Provenir.getValue("/Data/Request/Plan[" +i+ "]/PlanId="+planId+"/@*[name()='RoundDown']"); 
    config.Global_Variables.CalculatedAffordabilityLines[0].RoundDown.setValue(roundDown); 
    prov.log(0, "roundDown: " + roundDown); 
    maxDrawAmount = Provenir.getValue("/Data/Request/Plan[" +i+ "]/PlanId="+planId+"/@*[name()='MaxDrawAmount']"); 
    config.Global_Variables.CalculatedAffordabilityLines[0].MaxDrawAmount.setValue(maxDrawAmount); 
    prov.log(0, "maxDrawAmount: " + maxDrawAmount); 
    termMax = Provenir.getValue("/Data/Request/Plan[" +i+ "]/PlanId="+planId+"/@*[name()='TermMax']"); 
    config.Global_Variables.CalculatedAffordabilityLines[0].setColumn("gbeb23b1191604f5eb919d11192d5caf6", termMax); 
    prov.log(0, "termMax: " + termMax);   

    // Affordability calculations 
    maxLoan = config.Business_Logic.Scripts.Calculations.CalculateMaxLoan(mdi, termMax, monthlyRate); 
    // ***** 23012015 - MS - Per Robert, round to 2 decimal places. ***** 
    maxLoan = Number(Math.round(maxLoan + "e+2") + "e-2").toFixed(2); 
    prov.log(0, "maxLoan: " + maxLoan); 
    config.Global_Variables.CalculatedAffordabilityLines[0].MaxLoan.setValue(maxLoan); 
    affordabilityLine = Math.floor(maxLoan/roundDown)*roundDown; 
    prov.log(0, "affordabilityLine: " + affordabilityLine); 
    config.Global_Variables.CalculatedAffordabilityLines[0].AffordabilityLine.setValue(affordabilityLine); 
}
