    Hi,

    Your code snippet for iterating over XML attributes to extract currency and rate looks solid overall. However, there are a few syntax and logic issues that may need attention:

    Suggestions:

    1. Syntax Correction:

      • The line if EvaluateRate, xmlAttr.Value) seems to have a typo. It should likely be:
     
    if Evaluate(Rate, xmlAttr.Value) then

    1. Variable Initialization:

      • Ensure TargetCurrency and Rate are properly declared and initialized before use.

    2. Currency Check Logic:

      • The condition TargetCurrencies.Contains(TargetCurrency) assumes TargetCurrencies is a collection. Make sure it's defined as such (e.g., a List or temporary table).

    3. CurrencyExchangeRate Handling:

      • The CurrencyExchangeRate.Get(...) call should be wrapped in a conditional block to avoid errors if the record doesn’t exist.

    Cleaned-up Version:

     
    for i := 1 to xmlAttrCol.Count do begin
        if xmlAttrCol.Get(i, xmlAttr) then begin
            if xmlAttr.Name = 'currency' then
                TargetCurrency := xmlAttr.Value;
     
            if xmlAttr.Name = 'rate' then
                if Evaluate(Rate, xmlAttr.Value) then begin
                    if TargetCurrencies.Contains(TargetCurrency) then begin
                        if CurrencyExchangeRate.Get('EUR', TargetCurrency, Today) then begin
                            CurrencyExchangeRate.Validate('Exchange Rate Amount', Rate);
                            CurrencyExchangeRate.Modify();
                        end else begin
                            CurrencyExchangeRate.Init();
                            CurrencyExchangeRate.Validate('Currency Code', TargetCurrency);
                            CurrencyExchangeRate.Validate('Starting Date', Today);

    Let me know if you'd like help testing or extending this logic!

    Best regards,
    Daniele
